Low-cost desktop rapid prototype machine

The SD300 desktop 3D printer will make rapid prototyping capabilities available to a completely new family of users. The SD300 creates models using the LOM (laminated object manufacturing) method of building up layers, using shaped PVC sheets and gluing them together. It is driven by a CAD or solid modelling file of the object to be made, which it interpolates into the necessary number of layers – most of which will be uniquely shaped. The process is fast, clean and quiet, and thus ideal for an office environment; no special skills are required, so dedicated staff are not required. The resulting model is robust and suitable for use as a visual design aid; it is not brittle nor too delicate to withstand handling. It enables the user to realise a CAD file as a 3D model – to see and feel the reality of the virtual design. The SD300 is priced so that it is the lowest priced rapid prototyping machine on the market, says Unimatic Models made on the SD300 are accurate to within 0.25 mm, and can be produced up to 160 mm by 210 mm by 135 mm. The machine is about the size of a 3-in-1 printer/fax/scanner, and although it weighs rather more, at 35 kg it can be moved without lifting equipment.
