Advantages: 1. Metal body: suwit 3d printer is a full steel structure 3d printer, in addition to this, 99% parts of this printer are made of high strength or high tolerance materials that ensures high-precision printing, long term serve time and much better than wooden frame printer. 2.Thermostat: with insulating cover for constant temperature printing space, preventing edge warping and deformation while large prototype printing. And the cover is easily removed. 3.Large build size: build size is up to 250*250*450mm (l/w/h), far more than other available 3d printer in the worldwide market. 4.Durable nozzle: the extruder made by special materials and used advanced design technology, which is more stable and longer life. And can make 2 colors printing. 5.No block: the new generation nozzle has formed a perfect solution and can prevent block the nozzle. 6.High precision: imported bearing and rail, all parts made by cnc, accuracy of x, y is up to 0.01 mm, z to 0.015mm, and the minimum layer is only 0.04 mm. 7.Accuracy feeder: exclusively designed filament feeder, and using professional precision gear motor can ensure feed filament accurately. 8.High speed: highest speed printer in the market, travel speed is up to 250mm/sec, and print speed is up to 180mm/sec, which are more than reprap and makerbot. 9.Various filament: pla, abs, pva, and other kind can be used. We support to use pla, for no smell, environmental, degradable and easy to shape. Application: Suwit 3d printer can be used in the different areas, such as industry, architecture design, education, medical industry, cultural relic, food industry, accessories, etc. Packing and accessories: Our machine are packed by thickness carton, honeycomb board, and protective pe foam, which can protect suwit 3d printer in a good performance when you receive it.
