Stereolithography (SLA) Materials
SLA materials are categorized by the engineered properties they are replicating. At Xometry, we compare these by similar thermoplastics like polypropylene, ABS, polycarbonate, etc.
Polypropylene-like (more flexible)
- SLA Accura 25: A polypropylene-like SLA material that can simulate snap-fits due to its ductility and low fatigue. Color - white. (View spec sheet)
- SLA Somos NeXt: An extremely durable, polypropylene-like, SLA material with high versatility. Color - white. (View spec sheet)
ABS-like (general purpose)
- SLA Accura ABS Black (SL 7820): A durable ABS-like SLA material with an exceptional black finish useful for parts designed for injection molding. Parts may have a light paint coat for a consistent black finish. Color - black. (View spec sheet)
- SLA Accura Xtreme Grey: A tough SLA material similar to polypropylene or ABS which is widely used for snap enclosures. Color - grey. (View spec sheet)
- SLA Accura Xtreme White: A tough SLA material similar to polypropylene or ABS which is widely used for snap enclosures. Color - white. (View spec sheet)
- SLA Somos EvoLVe 128: An extremely durable SLA material with high versatility. Color - off white. (View spec sheet)
- *SLA Somos ProtoGen 18420: A durable, ABS-like, SLA material useful for parts designed for injection molding. Color - white. (View spec sheet) *Available via custom request.
- SLA Somos Taurus: An impact-resistant ABS-like material that exhibits a great balance of thermal and mechanical performance. Color - dark grey. (View spec sheet)
- SLA Somos Watershed Black: A durable, ABS-like SLA material with an exceptional black finish useful for parts designed for injection molding. Color - black (dark grey). (View spec sheet)
- SLA Somos Watershed XC 11122: A naturally transparent, ABS-like material, with excellent moisture resistance. Exhibits high clarity with secondary finishing. Color - translucent clear. (View spec sheet)
Polycarbonate-like (rigid plastic)
- SLA Accura 60: A naturally transparent, PC-like material, with excellent feature resolution. Exhibits high clarity with secondary finishing. Color - translucent clear. (View spec sheet)
- SLA Accura ClearVue: A naturally transparent, PC-like material, with excellent moisture resistance. Exhibits high clarity with secondary finishing. Color - translucent clear. A Quick Clear finish option is available with this material for a near-transparent part. (View spec sheet)
- *SLA Somos ProtoTherm 12120: A stiff, rigid material which can have higher heat resistance with a thermal post-cure. Color - translucent red. (View spec sheet) *Available via custom request.
- SLA Somos WaterClear Ultra 10122: A naturally transparent, PC-like material, with excellent moisture resistance. Exhibits high clarity with secondary finishing. Color - translucent clear. (View spec sheet)
Ceramic-filled composite (highly stiff)
- SLA Accura Bluestone: A ceramic composite, offering the highest stiffness of any SLA material. Ceramic-composite materials behave like porcelain. Color - faded blue. (View spec sheet)
- NEW-SLA Somos PerFORM: A ceramic composite, offering the highest stiffness of any SLA material. Ceramic-composite materials behave like porcelain. Color - light beige. (View spec sheet)
