3D Vision Printer, Dual Extruder With 2 FREE PLA Spools, PLA & ABS Filament Compatible, Assembled Desktop Printing

All 3D Vision Printers come with dual extruders. You will also receive 2 FREE 1KG spools to help you with your first build.

The new upgraded extruder is smaller, lighter, and faster to build. And since it’s designed from the ground up for 1.75 mm filament, it’s light-years ahead of past designs in reliability.

The layer alignment results in nicer prints and higher resolution, 100 micron inch.

We’ve completely overhauled the drive system to give the optimum positioning accuracy. The entire system has been upgraded to a sturdy 3/8″ diameter linear shafting. We’ve also switched to self-aligning, sintered stainless steel bearings. These are very forgiving to DIY assembly and provide a nice, smooth motion on the steel shafts. We’ve completely replaced the Z axis with a stepper driven, cantilevered stage. Guided by two of the linear shafts, this completely eliminates any Z wobble and results in nicely aligned layers. Using a high-angle lead screw, we were able to increase the speed of the Z axis from 150mm/minute to 1,000mm/minute. This means the layer changes are almost completely imperceptible.

The new electronics have been designed to make the printing experience easier than ever. The 3D printer connects to your computer via a standard USB cable thanks to a USB chip on the motherboard. We’ve also added full end stop support so that you never need to touch the XYZ axes ever again. When you hit print, the machine will automatically home itself, heat up, and begin printing. All you have to do is sit back and relax while your 3D printer does all the work. Living in the future is awesome. Oh yeah, and the electronics are all inside, so you don’t have wires dangling everywhere.

You may connect using a USB or you can simply print using the supplied 2GB SD card. Sometimes prints fail with USB connection because of PC hibernation or automatically shutdown. This was the reason we developed the SD card reader on the printer. Your 3D print just got faster and simpler.

1. Is your filament tangled?
Check that the spool is spinning smoothly on the mount.

2. Is the nozzle clogged?

Run the Load script from the onboard menus. Observe the plastic as it emerges from the nozzle. Does it drop straight down, or curl up toward the extruder? If it curls back up toward the extruder, the nozzle may be partially clogged.

3. Having trouble getting the first layer to stick well?

Some adjustments to the nozzle calibration height help.
