SLA

Glass-filled SLA resin for highly stiff, precise parts with a smooth matte surface. Suitable for evaluating fixtures, tooling and dimensionally stable prototypes.

High stiffness means limited flexibility. Elastic snap fits or repeated substantial bending require evaluation of other materials.

The properties below apply to V1 FLRG1001 under the stated test conditions. The Form 4 formulation FLRG1011 is separate. Printer, formulation and post-processing are confirmed before production.

Limitations and post-processing

Suitability depends on geometry, orientation, print profile and material condition. Drying, annealing, or washing and post-curing are material- and profile-specific. Material data do not certify a part.
