Large-format 3D printing builds parts over long cycles, where unfilled polymers warp and drift dimensionally as they cool. Infinite™ pellets are reinforced with glass fiber, which lowers the polymer’s coefficient of thermal expansion (CTE) and controls warping and shrinkage across big parts. Every grade is validated on major pellet-extrusion platforms including Thermwood LSAM and CEAD, with platform-specific print parameters available from Interfacial’s applications engineers. Each lot is produced on the same twin-screw compounding line used for full production and ships with a Certificate of Analysis (CoA) covering MFI, tensile, flexural, and moisture specs. Customers can start with 50–500 lb trial quantities and scale to commercial volume on the identical platform — backed by a PhD materials-science team, 30+ patents, and 40 million pounds of annual capacity across 8 twin-screw extruders.
