Introduction

     Originally developed at the Massachusetts Institute of Technology (MIT) in 1993, Three- Dimensional Printing technology (3DP™) forms the basis of Z Corporation’s prototyping process. 3DP technology creates 3D physical prototypes by solidifying layers of deposited powder using a liquid binder. By definition 3DP is an extremely versatile and rapid process accommodating geometry of varying complexity in hundreds of different applications, and supporting many types of materials. Z Corp. pioneered the commercial use of 3DP technology, developing 3D printers that leading manufacturers use to produce early concept models and product prototypes. Utilizing 3DP technology, Z Corp. has developed 3D printers that operate at unprecedented speeds, extremely low costs, and within a broad range of applications. This paper describes the core technology and its related applications.

How does Z Corp.’s technology work?

     Z Corp.’s 3D printing technology leverages 3D source data, which often takes the form of computer-aided design (CAD) models. Mechanical CAD software packages, the first applications to create 3D data, have quickly become the standard for nearly all product development processes. Other industries such as architectural design have also embraced 3D technologies because of the overwhelming advantages they provide, including improved visualization, greater automation, and more cost-effective reuse of 3D data for a variety of critically important applications. Due to the widespread adoption of 3D-based design technologies, most industries today already create 3D design data and are capable of producing physical models with 3D printers from Z Corp. The software that drives Z Corp.’s 3D printers accepts all major 3D file formats, including .stl, .wrl, .ply, and .sfx files, which leading 3D software packages can export. In addition to mainstream applications in mechanical and architectural design, 3D printing has expanded into new markets including medical, molecular, and geospatial modeling. Additional sources of data include CT/MRI diagnostic data, protein molecule modeling database data, and digitized 3D-scan data. As designing and modeling with 3D technologies has become more pervasive, developers have created a large number of software packages tailored for use in specific industries. A small sampling of 3D software packages that are directly compatible with Z Corp.’s 3D printers appear in the table below.

Mimics

     After exporting a solid file from a 3D modeling package, users can open the file in ZPrint™, the desktop interface for Z Corp.’s 3D printers. The primary function of ZPrint is to cut the solid object into digital cross sections, or layers, creating a 2D image for each 0.1016mm (0.004”) slice along the z axis. In addition to sectioning the model, users can utilize ZPrint to address other production options, such as viewing, orienting, scaling, coloring, and labeling multiple parts. When a user decides to print the job, ZPrint software sends 2D images of the cross sections to the 3D Printer via a standard network, just as other software sends images or documents to a standard 2D printer. Setup takes approximately 10 minutes.

3D Printing

     Z Corp. 3D printers use standard inkjet printing technology to create parts layer-by-layer by depositing a liquid binder onto thin layers of powder. Instead of feeding paper under the print heads like a 2D printer, a 3D printer moves the print heads over a bed of powder upon which it prints the cross-sectional data sent from the ZPrint software. The Z Corp. system requires powder to be distributed accurately and evenly across the build platform. 3D Printers accomplish this task by using a feed piston and platform, which rises incrementally for each layer. A roller mechanism spreads powder fed from the feed piston onto the build platform; intentionally spreading approximately 30 percent of extra powder per layer to ensure a full layer of densely packed powder on the build platform. The excess powder falls down an overflow chute, into a container for reuse in the next build.

     Once the layer of powder is spread, the inkjet print heads print the cross-sectional area for the first, or bottom slice of the part onto the smooth layer of powder, binding the powder together. A piston then lowers the build platform 0.1016mm (0.004”), and a new layer of powder is spread on top. The print heads apply the data for the next cross section onto the new layer, which binds itself to the previous layer. ZPrint repeats this process for all of the layers of the part. The 3D printing process creates an exact physical model of the geometry represented by 3D data. Process time depends on the height of the part or parts being built. Typically, Z Corp.’s 3D printers build at a vertical rate of 25mm – 50mm (1” – 2”) per hour. When the 3D printing process completes, loose powder surrounds and supports the part in the build chamber. Users can remove the part from the build chamber after the materials have had time to set, and return unprinted, loose powder back to the feed platform for reuse. Users then use forced air to blow the excess powder off the printed part, a short process which takes less than 10 minutes. Z Corp. technology does not require the use of solid or attached supports during the printing process, and all unused material is reusable.

Z Corp.’s 3D printing is fast

     Z Corp. 3D printing is the fastest additive technology commercially available on the market.Other companies often refer to their equipment as 3D printers, however these systems rely onprocesses using a vector approach or single-jet technology to deposit all build material. Z Corp.uses inkjet print heads with a resolution of 600 dpi (dots per inch), focuses on a drop-on-demand approach, and manufactures the only true 3D inkjet printers available. The technology allows printing of multiple parts simultaneously, while only adding a negligible amount of time to the print time for one part.

     In printing, especially 3D printing, the accuracy of the models depends on the ability to jet when and where required. This is a function of jet size and motion control. Z Corp.’s precise inkjet implementation results in high-definition, quality parts.

     Also contributing to the overall speed of the 3D printing process is the method used to distribute material. Z Corp. uses a spreading method for depositing more then 90 percent of the material, which is extremely efficient and fast. Z Corp.’s 3D printers dispense only a small percentage of the build material, the binder, through the print heads. Other additive prototyping technologies deposit 100 percent of the build material through a nozzle, resulting in very slow print speeds and lengthy prototyping turnaround times.

     The fundamental inkjet approach is the primary contributor to greater speed, although there are several other reasons why Z Corp. systems are the fastest. ZPrint software processes data in parallel with the printing of the part. While the 3D printer deposits the first layer, the software slices and processes the fifth layer. Some additive technologies process all tool paths before the job begins. Although the processing time may seem to be fast, it is often only a fraction of the total time it takes to build the part. It can actually take up to an hour to prepare a job with multiple parts using some additive technologies.

     Z Corp.’s 3D printers enable the stacking of parts vertically because they do not require rigid support structures. Producing parts with other types of additive technologies requires structural supports along the vertical axis, limiting the ability to stack or nest parts. With Z Corp.’s 3D printers, users can utilize the entire build area and produce multiple parts with only one set-up procedure, further reducing the total number of builds and processing time.

Z Corp.’s 3D printers produce high-resolution models

     Z Corp. first introduced high-resolution 3D Printing (HD3DP™) in 2005. The HD3DP concept is the result of a combination of print-head technology, materials advancement, firmware, and mechanical design. Z Corp.’s highly engineered inkjet print heads, with 600-dpi, high-resolution capabilities, are the product of years of research. Z Corp. leverages the engineered print heads in combination with proprietary firmware to control the print head during the printing process,accurately and precisely depositing colored binder in the areas indicated by the ZPrint software.

     Additionally, Z Corp.’s 3D printers control the print head movement while positioned extremely close to the powder, reducing inaccuracies related to fanning of the binder spray.

Z Corp.’s 3D printers are easy to use

     The straightforward user interface and simple part-making process make Z Corp.’s 3D printers accessible to everyone involved in product design. The materials used are non-toxic, completely safe, and do not require specialized operating environments such as a lab or a shop. Users can operate Z Corp.’s 3D printers right in an office rather than in a designated space with specialized requirements. Because of the intuitive ZPrint software interface and simple set-up procedures,anyone can efficiently operate one of Z Corp.’s 3D printers, eliminating the need for a dedicated machine operator. Z Corp.’s reliable technology allows its 3D printers to run unattended during the printing process, reducing user interaction to the simple setup and part removal steps, which generally take less than one hour.

Affordable printing solutions for you.

     Z Corp.’s 3D printers produce very little waste. The unprinted powder surrounds and supports complex parts during printing. Users can recycle all unused support powder.

     Thus, printed-part volume becomes the basis for all part-creation costs. Other additive processes require the building of solid support structures to support complex geometries during the printing process.

     Users have to discard these support structures after use, and the wasted material contributes significantly to the cost of additive technologies.

     Z Corp.’s 3D printers are dependable and a very user-friendly product, resulting in low operating costs. Modular design and standard ink jet printing technology combined to produce a reliable system that is straightforward to operate and easy to maintain.

     The use of an “off-the-shelf” print head allows for inexpensive, quick replacement of the system’s primary consumable component. The application of modular design techniques to the printer’s electronics, printing, and maintenance components makes the printers efficient to maintain with minimum downtime, further reducing costs.

     As it leverage the stereotype ink jet printers, it is also the lowest-cost of 3D printer, precised output, detailed surfaces and reliable. The approach results in material usage costs that are a fraction of other rapid prototyping technologies; finished parts cost $0.10 USD per cubic centimeter in materials. A hand held part can be produced for about $10 USD in material costs.

Color Models

    Z Corp. applies the proven 2D color inkjet methodology to 3D printing and produces the only 3D printers with 24-bit, full-color capabilities. When printing 2D images from digital files, computers convert the RGB values (Red, Green, and Blue colors displayed on the monitor) to CMYK colors (Cyan, Magenta, Yellow, and Black).

    Typically, a 2D color desktop printer will have a print head with three of the color channels, CMY, and another for black, K. Using these four inks, the printer combines several dots in each printed pixel though the use of ordered dither patterns to create the appearance of thousands of colors. The same principle applies to 3D printing. Z Corp.’s 3D printers use four colored binders: cyan, magenta, yellow and clear, to print colors onto the shell of the part. ZPrint software communicates color information to the printer within the slice data.

    Full-color 3D printing produces prototypes with the same coloring as the actual product. Users also use color to represent analysis results directly on the model or to annotate and label design changes to further enhance the communication value of the model.

    While color can be an essential communications tool, many 3D software packages do not provide a simple way to produce 3D files that include color data. To address this challenge, Z Corp. developed ZEdit™ software, a Microsoft® Windows® based program that facilitates the addition of color data to 3D part files. ZEdit is a tool for part coloring, markup, labeling, and texture mapping. Users also utilize it to map .jpeg files onto 3D part geometries. ZEdit software works with files from any of the leading 3D software packages.

Versatility

    Z Corp.’s initial focus was to produce a 3D printer for conceptual models but as adoption of 3D printing grew, so did the number of 3D printing applications. Z Corp.’s 3D printers have become versatile because of the natural flexibility of their delivery mechanism. The bonding process of loose powder into solid parts can be achieved, using variety of material. While the 3D printer remains literally same, users can change the building material to produce parts that suits their objective.

Z Corp. offers five type of materials:

1.High - Performance Composite Material
High-Performance Composite Material makes strong, high-definition parts and is the material of choice for printing color parts. It consists of plaster materials and additives that maximize surface finish, and feature resolution.

2.Direct Casting Metal Material
Direct Casting Metal Material creates sand-casting molds for non-ferrous metals.Users can use this process to create prototype castings without having to pay for labour work.

3.Investment Casting Material
Investment Casting Material fabricates parts that users dip in wax to produce investment casting patterns without molds. Users can utilize investment casting material to create high-quality castings with excellent surface finishes in a number of industries.

4.Snap-Fit Material
Snap-Fit Material creates parts with plastic-like, flexural properties, which are parts that can be curved or bent. Users can utilize snap-fit material to create plastic-like parts that snap into other components and assemblies.

5.Elastomeric Material
Elastomeric Material creates parts with rubber-like properties. Users utilize elastomeric material to produce accurate parts that are capable of absorbing the elastomer, which gives the parts their rubber-like properties.

    One of the important advantages of Z Corp.’s 3D printing systems is the array of material properties that are available for a 3D printed part. Users can infiltrate liquid resins to allow the part to take on the physical properties of a harden resin. This capability provides users with greater versatility without having to change out the primary materials in the 3D printer. Users can also use 3D printed molds for prototype blow molding and thermoforming, saving valuable time and prototype tooling costs.

ENGBusiness, that's how I call it !

     After dealing with so many subjects, I can see that this particular subject is actually what an individual needs. This class has taught me on methods of dealing with professional people, company and proper ways of dealing with real life workplace situation and also proper manners when communication with different level of people.

     So far upon finishing forth chapter, I can see that communications is not solely based on written and verbal but also through visual images, multimedia, facial expression and body gestures. From the last few chapters, we (students of ENGB213, class of Mr Ng Yu Jin) were taught about few ways of writing letters and paperwork and few methods like KISS(Keep It Simple & Short) and ABC(Accurate, Brief, Clear). We were also taught on ways to write about ourselves to impress others. Mr Ng Yu Jin also taught us that we need our own characteristic to be special or different from others.

     However, based on my own personal opinion, these don’t affect much on my english performance or any types of communication. So far, the most precious thing I have learnt from this class is doing presentation in a proper way. Every class, we as a group have to do a presentation just to sharpen our presentation skills. In the presentation, all the methods in the book are implemented into the presentation. It’s not the learning that I take notes of instead it’s the presentation skills that I have learnt so far that I will take notes for the rest of my life. It’s now not a fear factor to me anymore. Thanks to Mr Ng Yu Jin who have been sarcastically teaching us on ways to deal with real life working condition.

UNITEN EXPERIENCE

The time April of the year 2008, The place Malaysia. Its a chance to upgrade life to become successful and make my parents proud, first impression its going to be tough moving to new country and meeting new people, at first i felt like a n outsider, no friends no family no joy of being here.
To me UNITEN was normal, good example of a formal university i would say where there is no fun what so ever no parties, no frat houses to join, not even a basketball team so that made it more boring for me.
New semester began, now I am telling myself "sit in the front MO you have to understand everything the only thing you can do here is study no more fun".
Than life got really boring i wanted to move back to my friends family I didn't wanna study anymore, than I met my new friends Sakyer, Ken, and Bamband they were very nice and friendly they always asked me to eat with them, try to teach me Malay, and ask me to study with them. Now life is lot better now i have lots of friends witch i prefer to call family because we do everything together as a family, so i thank god for giving me them to help me on my quest, and hopefully we will all succeed on our mission, to graduate and become successful people in life.

Sorry i am late this weekend was my birthday and i got little busy.

Experiencing UNITEN

     It was July 2007 when my application to continue my studies in UNITEN got accepted. I have followed my sister’s footstep as I’ve seen UNITEN before when I was still in early age. After a few months of observation, I can see that UNITEN has good environment and the university does has a standard compared to other universities I’ve seen so far. So I was excited when I received the offer letter from UNITEN to further my studies after SPM. I never doubt UNITEN for its potential to provide good certificates to the students. As we all know, UNITEN is known well for it’s recognized certificates and professional study environment. So now it has been two years since I entered UNITEN. So far, I can see that most of the students and lecturers are working professionally.

     Surrounded by professional people, they thought me how to live in a real world, considering life in university is just one step away from dealing with real life situation and professional jobs. I have overcomed my fear of talking in English, doing presentation and communicate with people at different level. The course outline provided by the university tend to teach me ways of dealing with people, programs and also machines.

     It has been a great pleasure being a UNITEN student. I’m glad I was accepted by the university and I will make sure that I will do something for the community and let people know that it’s not me but it’s the UNITEN. “UNITEN generates professional” is not just a slogan but a true fact. Thanks for the wonderful two years and I hope that the following years will be just as great as it is now.

me, uniten and ........

I further my studies again in this place call UNITEN. Yeah for me UNITEN is great to students spend their money and more money to further their study.Currently I am taking Systems & Networking course and this is my first year of studies. So far so good. I have a lot of freind here and all my friend like me very much because I'm realy realy cool person. Hahahaha just kidding. One of my best friend in here is Najib. Hey Najib thanks because be one of my friend and help me everything. And also Mo, my foreigner friend from....... ,hey I dont know where is Mo from. He always pretending and act like me to look cool, maybe because I'm really really cool person. Oops!... i did it again, just kiding. Hey Mo i know you cool. At the college we've done many interesting work,work and work. I hope that I can learn something important while I’m studying at UNITEN. I agree with Najib that UNITEN can boost our chances in succeeding in our ambition and life and also to achieve many great things in life.

My take on business communication

If I was asked this question, "What is your thought on Business Communication". I would answer "Just what I was looking for, to prepare myself for the fierce and demanding working world".
Business communication teaches me the 5 methods of communication: written,verbal,visual images,multimedia and gestures, and its importance in gaining the attention of the receipient. In this modern era, the use of conventional method of communication,like verbal, is not enough. We now have to take advantage of advancement achieved in computer field, the multimedia.
Business communication that im learning right now in uniten, also gives me the opportunity to speak in front of a crowd,which was declined to me during my primary and secöndary school days. Without the valuable experiences, like all my other friends, I grew along with a "tumor", called, "stage fear ophobia". I was diagnosed with that "disease" during my muet test. Thank god it wasn't critical.
Business communication also taught me the importance of cover letter in promoting myself to the human resources of a company. Also the "TEN COMMANDMENTS" of reaping success in communication. I also learned to kiss, not kissing but k.i.s.s ,which means keep it short and simple.
I can go on and on about business communication because of it's praticality in real world, but like any good subject it need to be taught effectively, so that it's content can be absorbed by students. This job of teaching is done perfectly by my lecturer, Mr. YJ. His mix of sarcasm and profesionalisme, helps us to enjoy the his lecture. Thank you, sir.
Again, "what is my thought on business communication?". My answer, "just what i was looking for"

UNITEN

July 2007, I got accepted to University Tenaga Nasioanal (UNITEN) to further my studies on Foundation in Computer Science. Before that I also received many offers from other universities such as from Multimedia University(MMU) and Limkokwing but I choose UNITEN because UNITEN is one of the best university in Malaysia. In UNITEN, I have met many new friends not just from Malaysia but from other countries too. There are some international students from Indonesia, Arab Saudi, Iran, Sudan, and from Africa. After 1 year, I got accepted to continue my studies on Degree in System and Networking. Now I have 2 more years before I graduated from UNITEN. I hope that I can learn something important while I’m studying at UNITEN.

What I've learnt so far in my english class..

I've just complete up to the fourth chapter. The class is fun! I like it so much, now I know about effective communications, how to speak well, how to get peoples attention, using the right words, gestures, facial expressions etc. I like this class because I don't have to write that much, the lecturer will always encourage us to speak by having presentations, public speaking and so much more. Maybe some of my friends don't really like the class, I can see that because they felt like being tortured when they had to do the public speaking. After the last class, it seems like they've got the message that the lecturer want to expose ourselves with English and to have a very good and effective communication skills in the future.

Thank you Mr. YJ!!

regards & thanks,
Ahmad Najib

campus life..

It was last year, July 2008 i got accepted to further my studies in degree level here at UNITEN. Currently I am staying at the campus apartment and I am taking Systems & Networking course and this is my first year of studies. I've met many new friends with differences in their previous education background. We shared many new information, ideas and experiences. I've also met some foreign friends, they came from the middle east like Jordan, Iran, Iraq, Saudi Arabia even some of the came from Africa too. It a good thing because they have big interest in knowing our country, cultures, peoples and foods! I enjoy all those physical activities with my friends, we have a mini stadium, pool, golf driving range, paintball and many more. At the college we've done many interesting projects, presentations, public speaking, quiz etc. It was fun and that what makes my campus life is interesting and unforgettable life experience. I met many lecturers and lab instructors, i like to be taught by some of them because they are kind hearted and friendly, but not to say that the other lecturers are not the same like them. I am hoping that UNITEN can boost our chances in succeeding in our ambition and life and also to achieve many great things in life.

regards & thanks,
Ahmad Najib

My interesting uniten experience

It has been two years, since I first set my foot in uniten. I choose to join uniten because of uniten's track record of producing competitive and profesional graduates. Although I choose to evolve in uniten, I still need 2 be approved by the uniten's student enrollment department, in order for me,to get a seat in uniten.
Trust me when I say it, I got my place in uniten, the hard way.Strings of poor result in my SPM and STPM didn't help my ambition of joining uniten. I still dared to dream of joining this prestige university and it took an "appeal letter" and few trips to the registar's office, for me to convince them, I'm both serious and ambitious.
I won the "battle of will", but still left with a bad taste in my mouth. The reason for that was because I was offered, foundation in computer science instead of, degree in mechanical eng. Finally, I decided to take the course offered to me with a heavy heart and promise myself to do my level best.
Im doing rather well, for a guy, who once got "0" for mathematics and chemistry, a guy who once was last in his class. Over the 2 years in uniten, I've had to deal with uniten's staff and official, in more than one ocassion. They have always been polite and helpful to the students. They don't spoon feed you, instead they point you to the right direction, we still "have to do the walking".
I still have 2 years to go and i'm still evolving, thanks to the platform that has been laid infront of me by uniten. Every new semester is different and more challenging than the previous semester, which makes it more exciting.
Overall, I can only say that, it has been a life changing experience studying in uniten. . .
