Las tecnicas de prototipado rapido mas utilizadas son la Estereolitografia (SL), la Sinterizacion Selectiva por Laser (SLS), la Impresion Tridimensional (3D Printing), el Modelaje por Deposicion Fundida (FDM) y el Thermojet
. Todas estas se basan en el principio de adicion por capas del material, que corresponden a los "cortes" axiales de la estructura anatomica examinada (3).
The used system, 3D Systems' Thermojet
, was introduced in 1999 and the implemented print head contains 352 nozzles.
A new version of the FTS ThermoJet
temperature cycling system features enhanced data logging capabilities, which enable it to be used for device characterization through advanced trending and data analysis.
To produce the wax prototype, Sandvik uses a wax thermojet
, a machine that is similar to an inkjet printer.
Mueller has built a small monopoly in the RP world, assembling the world's largest single collection of Thermojet
machines, with seven.
For the same target market, 3D Systems has ThermoJet
, which costs about $50,000.
ranges from $49,995, for the ThermoJet
printer, to $799,000 for the high-end SLA 7000 system.
In 1995, the first of these systems on the market was the Actua modeler from 3D Systems, which now has a new and faster version, called ThermoJet
(see below for details).
Once a design measures up to parameters within the program and it's time to build a plastic model for the final review, engineers (anywhere with access to the Internet) click on their print icon and the ThermoJet
solid object printer at VFED cranks out components, to scale.
, a thermopolymer material, is used to build layer upon layer of material that will put a 3D concept model directly in the hands of a designer within hours.
Each individual electrostatic inkjet is activated by an electrical signal and instantly dispenses thermopolymer material (a nontoxic, fumeless plastic called Thermojet
450) on demand.
Other modeling processes that also are found throughout the industry are ThermoJet
methods, which also create solid models.
