3DP
Unless otherwise noted, all FirePick™ designs are 3D printable in PushPlastic 3mm PLA using Lulzbot Mini with Lultzbot Cura PLA (eSun) profile, QuickPrint Standard settings (i.e., no support). Lulzbot provides a global standard of reference but these designs should be 3D printable on any 3D printer with appropriate settings.
FirePick parts are structurally proportioned for printing with PLA 3DP filament. PLA is a bioplastic made from agricultural products (v.s non-renewable dead dinosaurs). Currently classified as recyclable resin #7, PLA has high potential for re-use. PLA is also classified as not a health hazard, which is critical for in-home printing.
PLA has a heat deflection temperature (HDT) of about 60°C or 135°F at which it starts losing its shape. This means that PLA stepper mounts typically require steppers running cooler at lower currents than capacity. For example, a Pololu #1209 Nema14 stepper is rated at 1A but will run much cooler at 60-80% of nominal current (e.g. 600mA). In certain cases, it is helpful to anneal PLA improved performance of parts under load at high temperatures.
Although FirePick 3DP designs are optimized for PLA, they should also be printable in other materials such as nylon, etc. to take advantage of particular properties.
