SLS plastic offers high impact strength
The DuraForm XR300 selective laser sintering plastic is translucent, white, flexible and has good chemical resistance and elevated impact strength.
Purchases double rapid prototyping capacity
The Viper Pro SLA System manufactures parts with exceptional feature details, accuracy, surface finish and large part size that are ordinarily associated with CNC machining.
Tooling inserts and metal prototypes created with 3D Systems' high-productive processes are stress-free and 100 % dense compared to other metal-laser-sintering product offerings.
The indirect metal-laser-sintering process is well suited for complex metal parts since large surface supports are no longer required.
The Accura SI 40 material for stereolithography combines durability with improved temperature resistance.
High elongation, flexural modulus and temperature resistance are similar to ABS plastic materials.
The Software Version 3.1 for SLS systems (selective laser sintering technology) enables the simple identification of parts by adding a physical name tag with personalised text to each part.

Rapid prototyping handles large automotive jobs
The Sinterstation Pro 230 SLS system transforms computer-aided design (CAD) data into ready-to-use, accurate and durable three-dimensional plastic parts.
RP models help blind boy to see new home
Nine-piece model is built on a 3D Systems SLS system with DuraForm PA plastic, a durable and functional nylon material that has excellent surface resolution.
This is particularly relevant for identifying individual parts in build processes with similar geometries, for example the production of 200 hearing aid shells in one build.
The software also includes an improved slicing algorithm and a new smart feed function for optimisation of material supply utilisation.
For SLA systems (stereolithography technology) 3D Systems presents the new Buildstation 5.3 and Lightyear 1.3 Software.

In addition to improved handling, the software allows for considerably higher productivity of the process on using an optimised surface finish scan (smart best surface finish).
The software also provides new build styles for Accura SL materials.
3D Systems will also give an insight into development projects for laser sintering materials for 2003.
This is the first time in the history of laser sintering that the company will offer an aluminium material for the direct manufacturing of metal parts.
It is the ideal material for parts which are currently created by die casting.
The direct manufacturing of parts on SLS Systems saves tooling costs and offers increased freedom of design.
Parts can be more complex and can form re-entrant shapes.
At EuroMold 2002 3D Systems will show first samples of aluminium parts, created in the 3D Systems R and D department on a Vanguard SLS System.
As a step closer towards production tooling the company is investigating an A6 steel material.
The required higher durability will be achieved by higher tool hardness, which requires increased finishing efforts compared to LaserForm ST-200.
For advanced digital manufacturing (ADM) applications, in particular in commercial aerospace, 3D Systems is developing a flame retardant polyamide material for selective laser sintering systems to be used as a functional plastics material.
Applications include components for air ducting systems.
The fire retardant polyamide material will be FAA (Federal Aerospace Association) certified.
Initial tests have already been passed and the new materials will be launched during 2003.
With advanced digital manufacturing (ADM) 3D Systems extends the applications of rapid prototyping processes to true flexible manufacturing of batch production.
Benefits include higher productivity, shorter lead times, lower capital investment and more cost-effective custom and short-run production.
Designers are free to create functional properties without being limited by the final manufacturing process.
"With ADM we are ahead of the industry.
We have an increasing number of customers applying our technologies as the manufacturing process", says Sandra Seitz, Product Manager Europe at 3D Systems.
In aerospace, air ducting systems that were conventionally produced by rota moulding of segmented parts are now directly manufactured on the selective laser sintering systems.
In the field of medical technology individual housings for inner hearing aid shells are directly created from polyamide materials.
In the jewellery industry the Viper si2 SLA system is used for the production of investment casting patterns.
Another application includes the electronic industry where connectors are being produced directly on an SLA system for short-run-manufacturing of lot sizes between 100 and 10,000 parts".
