ThermoJet solid object printer now available from Cadtek

Keywords Rapid prototyping

Cadtek has announced the immediate availability of the ThermoJet solid object printer from 3D Systems. ThermoJet is the debut product for Cadtek's Bix distribution division, formed following the acquisition of Nottingham-based Bix Limited in April 1999. The new technology is set to pave the way to an entirely new philosophy of conceptual communication and design verification.

"Most design engineers today have to communicate their concepts through flat drawings and - sometimes - renderings", says Allan Behrens, Cadtek Vice Chairman. "But there is no substitute for the ability to hold a design in your hand and until now this has meant calling on the services of specialist model-making bureaux or investing in expensive rapid prototyping technology. ThermoJet brings physical concept modelling into the design office" (see Plate 10).

ThermoJet uses the concepts and technologies of solid object imaging pioneered by 3D Systems 13 years ago, and now used worldwide in corporate design and engineering offices. But ThermoJet - with a UK list price of £35,000 for single units - produces its output quickly and affordably in a clean office environment.

"ThermoJet is an exciting new development simply because it makes the advantages of solid object imaging available to many more businesses", says Dr Richard Balanson, 3D Systems president and chief operating officer. "Now you can finish the design work on a new product and hold a sample of that product in your hand within hours. ThermoJet offers the flexibility to make changes or modifications easily and to individual specifications - it's a tool for mass customisation".

Specifications

ThermoJet works by depositing layer after layer of a patented thermopolymer, thus building up a solid model. Each layer is "printed" using slightly modified inkjet technology called multi-jet modelling (MJM), with a resolution of 300 x 400dpi. Models can be built up to maximum dimensions of 250 x 190 x 200mm, and ThermoJet will interface with all standard UNIX and NT platforms.

Applications

ThermoJet's ability to turn an idea into a physical model has significant benefits. A designer who has just created a mechanical part using computer-aided-design (CAD) software can send the file to ThermoJet over an ordinary office network. Within hours, ThermoJet produces a sample in a plastic-like material that the designer can hold and evaluate. The part then becomes a real-world example of what may be difficult to comprehend when viewed as a complex CAD image on a computer screen.

In addition, ThermoJet allows designers to detect flaws immediately. Users can share samples with customer focus groups to obtain useful feedback, or generate ideas for product packaging or potential marketing programs.

Because ThermoJet files can be sent over any network, including the Internet, the machine can be used as a "3D fax" to send models to other cities or continents in moments, for output within hours. This is especially valuable when complex designs must be communicated in a multinational, multicultural environment.
