Fortus 900mc 3D Production System gains four new materials

Paul Boughton
Stratasys is making four more build materials and one more support material compatible with its Fortus 900mc 3D Production System. The materials include Ultem 9085, PC-ABS, PC-ISO, and ABS-M30i.
These options more than double the number of materials compatible with the Fortus 900mc and they provide an array of mechanical properties from which to choose, such as FST (flame, smoke, toxicity) compliance, heat resistance, medical sterilisation capability, strength, and flexibility for prototyping and production. Stratasys materials previously compatible with the 900mc are ABS-M30, PC, and PPSF/PPSU (polyphenylsulfone).
Patrick Robb, Fortus product manager, states: "Stratasys built its leadership position in direct digital manufacturing and prototyping by helping customers build stable, strong, and durable parts for testing and end-use. These additional materials make the Fortus 900mc a solution for more advanced applications in both prototyping and direct digital manufacturing for Aerospace, Medical, and other industries."
Sabic's Ultem 9085 is a strong and lightweight thermoplastic widely used in aircraft interiors and other transportation applications. The material is heat resistant to 160 degrees C and has full FST compliance. It offers a very high strength-to-weight ratio and flexibility, making it an excellent material for applications requiring advanced mechanical properties. In addition to aerospace applications, Ultem 9085 benefits other industries requiring strong, lightweight and heat-resistant materials, including the marine product and automotive industries.
PC-ABS is one of the most widely used industrial thermoplastic blends and is commonly found in automotive, electronics and telecommunications applications. The material provides customers with the same strength and heat-resistance characteristics as previously available Stratasys PC material but with increased flexibility.
The addition of PC-ISO provides users with a tough polycarbonate material that can be sterilised for medical device or surgical jig and fixture production or prototyping. It is also useful in food and pharmaceutical handling applications. The material is suitable for applications requiring ISO 10993 certification or ethylene oxide (ETO) sterilisation. It also has high impact and flexural strength, and can handle high temperatures.
Like PC-ISO, ABS-M30i is a biocompatible material for direct digital manufacturing applications in the medical, food, and pharmaceutical equipment industries with ISO 10993 or ethylene oxide (ETO) sterilisation requirements. ABS-M30i offers substantial improvements over standard Stratasys ABS, including tensile strength, impact strength and flexural strength. ABS-M30i is up to 67 per cent stronger than Stratasys' previous ABS formulation. Bonding strength between layers is more than doubled, thereby expanding its capabilities for functional testing or production parts.
Like other additive fabrication methods, the Stratasys FDM process requires a disposable material to support features such as overhangs. Soluble supports automate the support removal process because they are dissolved rather than being removed manually. Compared with its predecessor, the optional SR-30 soluble support material delivers up to a 69 per cent reduction in dissolve time in an agitation tank, and up to a 46 per cent dissolve time reduction in an ultrasonic tank.
