Material	Description	Advantages	Considerations	Applications
DuraForm Polyamide (PA)	Used to build durable, functional models, this white nylon-like material provides an accurate part with good detail.	Durable, higher strength than SLA Requires less post-processing than SLA Can be primed and painted Can be machined	Less detail than SLA Slightly less accurate than SLA Tolerances +/- 0.010 (Dependant upon part geometry)	Concept models Fit and function Excellent for show display models that receive excessive handling
DuraForm Glass-filled (GF)	Used to produce rugged, engineering thermoplastic parts that withstand aggressive functional testing	Increased stiffness, heat resistance and mechanical integrity (relative to PA) Perfect material for extreme testing		Durable parts without tooling Heat and chemical resistant Excellent surface finish
DuraForm Aluminum-filled (AF) Plastic	An engineered composite with the durability of an injection molded part and the appearance of cast aluminum	Offers toughness of injection-molded ABS and polypropylene Produce durable end-use parts without tooling Create accurate and repeatable parts as demanded by manufactures.		Functional pro types or end-use parts that require high stiffness and/or heat resistance Accurate, durable master patterns Parts that require the look and feel of cast aluminum
DuraForm EX Plastic	This impact-resistant plastic offers the toughness of injection-molded polypropylene and ABS and is suitable for Rapid Manufacturing.	Rapidly produce parts with the look and feel of cast aluminum Address broad applications requiring high stiffness and heat resistance Minimal finishing required Excellent dimensional accuracy Consistent, repeatable part quality Reduced cost per part		Complex, thin-walled ductwork Housings and enclosures Impellers Connectors Consumer sporting goods Vehicle dashboards and grills Bumpers Snap-fit designs Living Hinges Functional prototypes that require end-use performance properties. Appropriate for low- to midvolume rapid manufacturing.
DuraForm Flex Plastic	Elastomeric material with rubber-like flexibility and a range of Shore A hardnesses. Infiltration adds colors and improves burst strength.	Outstanding toughness Excellent impact resistance Repeatable mechanical properties Easy to process Good powder recycling characteristics		Complex, thin-walled ductwork Housing and enclosures Impellers Connectors Consumer sporting goods Vehicle dashboards and griles Bumpers Snap-fit designs Living hinges Functional prototypes that require end-use performance properties. Approproate for low- to mid-volume rapid manufacturing
DuraForm PP 100 Plastic	Sintering material with the toughness and durability of molded polypropylene; with excellent chemical resistance and good feature resolution.	Test on realistic and challenging enviroments Properties comparable to molded polypropylene Build parts up to 900 mm long		Prototypes where toughness and durability are essential Advanced prototypes where actual polypropylene Direct or bridge manufacturing where polypropylene properties are desirable
DuraForm HST Plastic	Improved strength, stiffness, and thermal performance compared to DuraForm GF, more consistent mechanical properties than carbon fiber-filled materials.	High specific stiffness Elevated temperature resistance Good powder recycling characteristics Excellent surface finish		Housing and enclosures Impellers Connectors Consumer sporting goods Functional prototypes that approach end-use performance properties Parts requiring machining or joining with adhesives Thermally stressed parts
CastForm™ PS plastic	Thermoplastic elastomer material with rubber-like flexibility and functionality.	Create complex patterns without welds or joints Reduce lead times resulting in faster time to market Compatible with autoclaves, low-temperature furnaces, and vacuum plaster casting methods Easy to assemble and repair patterns Rapidly test new designs in iterative process Functions like foundry wax and is “foundry friendly” Low residual ash content (less than 0.02%) Short burnout cycle Easy-to-process plastic Good plastic powder recycle characteristics		Create patterns directly rather than through indirect methods Complex investment casting patterns Reactive metals like titanium Low melt-temperature metals such as aluminum, magnesium and zinc Ferrous and non-ferrous metals Economic, low-volume production castings without tooling Smaller parts can be joined to create very large patterns Sacrificial, expendable patterns
