3D Modeling: Using the Latest Innovations in Print

As Jay Leno once said, 3D printing technology is “pretty amazing.” Now, more and more people are becoming fascinated and interested in learning more about it. But what exactly is involved in 3D modeling, and moreover, how can printers get in on this latest technology craze?

Z Corp., located in Burlington, Mass., develops and manufactures printers and scanners that produce 3D models from computer-aided design (CAD), building information modeling (BIM), and other digital data. Companies use Z Corp.’s 3D printers to make prototypes ranging from toys for market feedback to fan blades for functional testing. Similar to how conventional desktop printers provide a paper output of documents, 3D printers provide 3D CAD and BIM users a physical prototype of objects such as a mobile phone, a camera, or a scale model building.

Companies including MTV, Nike, Converse, and Electronic Arts Inc.—creators of the video game Spore—use Z Corp.’s 3D technology for product design and prototypes.

How Is it Done?

“What’s involved in the 3D process itself is the software that’s used to generate the file. The software is broken down into three categories: mechanical and design such as Autodesk, architectural software such as Bentley Component and Form Z, and animation-oriented software such as 3DS Max,” explained Scott Harmon, vice president of business development for Z Corp.

“The 3D printers then take the design and generate a replica of it, but in order for it to be printed, the model has to have volume: It needs to be a sphere, not a circle,” he said.

“Z Corp.’s 3D printers suit applications from high school education through demanding commercial environments. Our 3D printers are the fastest on the market, have the lowest operating costs, and are affordable. The entry-level ZPrinter 310 Plus is a monochrome machine that builds volume of 8x10x8 inches. The mid-range ZPrinter 450 is a full color machine mixes color on the fly. It prints the same volume as the 310 Plus and makes it easy to create creature features,” Harmon noted.

The ZPrinter 650 is considered Z Corp.’s “high end” machine and prints in high definition full color by adding a black channel. The volume output is 10x15x8 inches. Z Corp. machines feature four-color printing through a layer-based system rather than one line at a time. Z Corp. also offers material systems for each printer to satisfy varying modeling needs. The material options allow for customization of model properties for each application.

Many 3D printers do not require an industrial environment to operate. Roughly 18,000 machines in the 3D printing industry are priced below $100,000, but even if you obtain the printers to perform capabilities, “if you don’t have the 3D software, you won’t have a use for the printer,” stated Harmon.

Printing Statues and Avatars

“For games like World of Warcraft, Spore, and Rock Band, you can have your avatar printed using this type of technology,” he further noted. Customers can order printed characters from World of Warcraft through www.figureprints.com. FigurePrints are custom statues of World of Warcraft characters created using 3D color printing machines. The artists “pull your character from the virtual world and bring it to life.”

FigurePrints’ servers pull character data from the World of Warcraft Armory, create a 3D model, and lets customers pose it any way they like. On the Web site, they can hit “Print” and the software prepares the model for printing. Artists finish the process by turning the design into a collectible figurine, and once it has passed the artists’ inspection, the print is packaged and shipped to the customer.
