RP system uses 'super thin' layers to
build in 3D
Rapid Prototyping system produces accurate, smooth and durable 3D workpieces, using a dispensing head, which lays down 'super-thin' layers to build up a design in three dimensions.
The very latest in rapid prototyping technology, manufactured by Objet, is now being made available to UK design, research and development specialists, through Unimatic Engineers, for advancing their Design and Technology capabilities to a whole new level Objet has appointed Unimatic as their exclusive agent for the education and research sectors in the UK and Ireland

Objet's Eden Rapid Prototyping system produces accurate, smooth and durable three dimensional workpieces, using PolyJet photopolymer-jetting technology.
With this a dispensing head traverses back and forth laying down super-thin (16-micron or 0.0006in) layers to build up the design in three dimensions.
"Rapid prototyping technology is changing all the time," explains Unimatic's Liron Noy.

High precision ballscrews are wear resistant
A comprehensive range of high-precision ballscrews, that give precision translation of rotational into longitudinal motion, is available in a two sizes and different pitches.
"And the PolyJet advances the state of the art on several fronts".
"Most importantly PolyJet satisfies Unimatic's strict requirements that any machine we introduce must offer best in class performance." Its industrial credentials can be seen from its impressive list of customers, which in Europe alone includes VW, Audi, BMW, Opel, Bosch-Siemens, Playmobil, Ford, Logitech, Gillette and many others.
Objet Geometries has built a global reputation for ultra-thin layer rapid prototyping systems and for developing its own resins.
Its technology is protected by more than 40 granted and pending patents.
The latest generation of PolyJet accurately jets 600 x 300 dots/in in super thin layers which dry almost instantly, so that the design is quickly created.
In use the jetting head slides back and forth along the X-axis, like a line printer, depositing a single layer of photopolymer onto the build tray.
Immediately after building each layer, ultraviolet bulbs alongside the jetting bridge emit UV light so that each layer is cured and hardened before the deposition of the next.
Objet's jetting block uses eight heads and sophisticated software tools which enable all the heads to work in perfect harmony, synchronously jetting identical amounts of resin onto the tray.
The result - a perfectly smooth and even surface.
Two different materials are used for building: one material is used for the actual model, while a second, gel-like photopolymer material is used for support.
When the model is completed, a water jet easily removes this support material.
"We have demonstrated the PolyJet to many people who already use our material cutting machines and the reaction is incredibly positive," says Noy. Request a free brochure from Unimatic Engineers ...
"Everybody is impressed by the sophistication and quality of the workpieces we can make, and most immediately think of something specific they would like to do with it.".
