The Sermoon D3 is tailor-made for industrial design. Be it prototyping, jigs & fixtures making, or design verification, it gets them all covered. It can even mass-produce some small but oddly shaped parts or products. The beauty is that it delivers prints rapidly with stable, high quality in a cost-effective way. Industrial Grade Stability Sturdy frame featuring thick metal plates and 4 vertical aerospace aluminum profiles. All the X,Y and Z axis are assisted with stainless steel linear shafts of 60HRC hardness. The printer holds well against the inertia force of the moving printing head. 720h (30 days) non-stop steady printing* 8,000h failure-free steady printing* Precision-made toMinimize Mechanic Errors The integrated XY axis gantry system is CNC machined with 0.0lmm precision for a seamless fit. The precise high-torque motors and durable timing belts and pulleys further reduce mechanical errors and boost accuracy. Reliable Extrusionat 300℃ Temperature The "Sprite" Dual-Gear direct drive extruder delivers strong extrusion and retraction force. The inner-polished copper alloy nozzle and bi-metal heat break work smoothly at a lasting high temperature with less heat creep. And, it has the two large 5015 cooling fans. Big But Also Delicate Sermoon D3 offers a generous 300mm×250mm×300mm (11.8"x9.8"x11.8") build volume. Meanwhile, this stable and accurate machine creates breathtakingly delicate prints featuring 0.1 mm accuracy, with layer texture hardly visible. Up to 5 Times of Printing Speed The advanced stepper motor driver chip enables 1/256 microstepping, realizing smooth printing at up to 5 times of speed. The production capacity will increase by several times for a given period of time. PLA-2 times of speed on default* PLA-Up to 3 times of speed* ABS-Up to 5 times of speed*
