Proto-Pasta Protopasta 3D Printer Filament, PLA Filament 1.75mm, Brass Filled PLA, 500g Spool

Introducing Brass-Filled Metal Composite HTPLA. Using real brass powder, we've created a premium heat treatable 1.75mm filament for 3D prints that finishes just like real metal! Our brass composite filament is as versatile as it is beautiful, printing like plastic, but finishing like real metal for beautiful, durable parts from most standard 3D printers. Material Data Base resin: HTPLA - Heat Treatable PLA Particle size: less than 250 microns (0.25mm) Odor: low or no Density: Approx. 2.30 g/cc Length (500g): 97m (1.75mm) and 36m (2.85mm) Heat treating: 110C (225F) for 10 min or as required for the desired result Total loss of stiffness (before heat treat): 50-60C (Tg) Total loss of stiffness (after heat treat): 150-175C (melting) Dimension change (before heat treat): 0% X/Y/Z Dimension change (after heat treat): 1.5% shrink X/Y and 1% growth Z typical but please calculate and confirm for your specific print and process Printer Settings Speed: 10-20 mm/s 1st layer, 20-80 mm/s rest of part Nozzle Set-point: 185-215C (hottest on 1st layer for best adhesion) Nozzle Actual: maintain set-point, reduce speed if less than Nozzle Type: Standard or wear-resistant for extended use Nozzle Diameter: 0.6mm or larger preferred, 0.4mm okay with 0.25mm minimum for experts Layer thickness: 0.15-0.20mm recommended for a balance of quality, reliability, and productivity Bed Temperature: Room-60C (over 60C can worsen warp) Bed Preparation: Elmers purple disappearing glue stick or your other favorite PLA surface preparation
