High-volume, high-resolution wax parts

Paul Boughton
3D Systems Corporation is launching the Projet CPX 3000 3-D Production System, a new high-definition 3D printer designed for high-volume, high-resolution production of finely detailed Realwax patterns from digital data. These Realwax patterns can be used for direct investment casting using standard materials and procedures.

The Projet CPX 3000 3D Production System uses 3D Systems' patented and proprietary Multi-Jet Modeling (MJM) technology combined with new Visijet CPX200 wax build material and new Visijet S200 dissolvable wax support material to produce 100 per cent Realwax patterns that are designed to perform like injected wax patterns in investment casting processes. This production system is equipped with two selectable build modes: a high-definition (HD) mode for high-speed, high-definition production of small to large parts with excellent surface finish; and an extreme high-definition (XHD) mode that delivers a 16-micron layer thickness for extremely high-definition production of parts with the delicate fine-feature detail that are common in many micro-casting applications.

According to 3D Systems, the Projet CPX 3000 system is the only currently available additive fabrication system that is capable of producing easy-to-cast, high-precision 100 per cent wax patterns produced at best-in-class production speed and throughput. This new integrated process and materials' production tool is suitable for producing wax patterns for jewellery, apparel, medical instruments and devices, mechanical parts, figurines, replicas, collectables and more. It builds high-quality patterns, including highly complex geometric shapes, that traditional handcrafting techniques and milling processes are unable to create.

Designed for high-volume, high-efficiency production, the Projet CPX 3000 Production System benefits from part nesting and stacking to utilise the entire build volume for longer-run unattended operation. Its proprietary single-pass print-head design facilitates the building of multiple parts at the same time without sacrificing build time.

Previously available systems in the marketplace have typically been too slow for demanding manufacturing environments or have only been able to produce patterns from photo-curable materials, which can present challenges to achieving desired casting results. The new Projet CPX 3000 3D Production System is claimed to be the only commercially available system that offers both high production output and 100 per cent real wax patterns that melt and burn out just like standard casting wax. Its new dissolvable support system is quick and easy to remove, leaving smooth support-side surfaces. Both build and support materials are environmentally friendly and require no special handling.

3D Systems plans to start shipping the Projet CPX 3000 System during the fourth quarter of 2008 and will provide live demonstrations and training on this exciting new system at its World Conference from 20-23 October 2008, in Charlotte, NC, USA.
