Processing

Layer adhesion - Tendency to warp. Use extra adhesives and/or print slow for first layers; Extrusion rate - Normal build rates according to extruder capabilities; ca. 40mm/s; Geometries - Fine and complex designs possible, include extra support when printing >50° angles; Ease of printing - Printing in open frame is possible for the experience user.; Post-processing - Excellent post-processing with all common technologies. Keep processing temperature in mind when milling, drilling, etc. Join parts using MEK, 2K adhesives or super glue

Performance

Stress - High stress suitable with ABS like performance; Bend & Flex - Medium resistance to bend and flex; Heat - Suitable for temperatures higher than 80°C; Mechanical Resistance - Good mechanical and impact resistance; Environmental Resistance - UV resistant & weatherproof, good chemical resistance; Eco Footprint - Recycling and repairing possible; Surface - Matt surface, easy postprocessing
