It is perfectly normal that your cooling fan breaks or nozzle gets damaged in 3D printers. Other parts may go dysfunctional. Cables and Heading Platform requires replacement.
We are stocked with some spare 3D printer accessories of the parts which usually get damaged. Simple and Easy replacement.
If you are new to 3D printers, the experience could be quite jarring. Every step from calibration of printers to achieving a desirable finish print result could go counterintuitive. And there is another notorious problem for every printers, from cheap RepRap to easy ready-to-use printers: the clogging of nozzle. You are in the middle of some important print and there it goes, air printing, which really needs the dissection of extruders and nozzle to clear off the clog. Also for RepRap printers, using the same slicers setting for another—next to previous successful print– can go totally different than you intended, without any specific reason.
And sometimes even if everything goes fine, your printer might display some strange unknown error, refusing to print. The experiment with various printing materials itself is not free from glitch and jerks, every different printing material need different slicer configuration. Oftentimes ABS print could never complete with minor curls or warping no matter how hard you try.
All those problems, you can confidently leave to the deft hands of our expert handlers of 3D printers.
