It prints like PLA on an open-architecture FFF\/FDM printer; after firing in a kiln you have a 100% copper part.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMetal content:\u003c\/strong\u003e 86.0%–90.7% copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilament density:\u003c\/strong\u003e 4.3–5.0 g\/cc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFormats:\u003c\/strong\u003e 1.75mm and 2.85mm spools, and pellets (pick in the variant selector)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNozzle:\u003c\/strong\u003e 0.6mm hardened steel, standard flow\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePrinting\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePrints similar to PLA with minimal to no warping\u003c\/li\u003e\n\u003cli\u003eFeed the filament straight into the extruder\u003c\/li\u003e\n\u003cli\u003eDo not dry it: drying degrades the binder (it is less hygroscopic than PLA)\u003c\/li\u003e\n\u003cli\u003eAlso works in 3D printing pens\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSintering setup\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDebind:\u003c\/strong\u003e bury the part in \u003ca href=\"\/products\/sintering-refractory-ballast-al2o3\"\u003eAl₂O₃ ballast\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSinter:\u003c\/strong\u003e bury in \u003ca href=\"\/products\/sintering-refractory-ballast-magnesium-silicate\"\u003eMagnesium Silicate ballast\u003c\/a\u003e and cover with \u003ca href=\"\/products\/virtual-foundry-sintering-carbon-0-5kg\"\u003eSintering Carbon\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHold it all in\u003c\/strong\u003e an \u003ca href=\"\/products\/sintering-crucible-alumina\"\u003eAlumina Crucible\u003c\/a\u003e inside a kiln such as the \u003ca href=\"\/products\/firex-sintering-kiln\"\u003eFireX\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eExpect roughly 90–95% density after sintering.
