Most of us do not familiar with the 3D printer price and the cost. We all want to find cheap 3D printer. Digital 3D color printing is a new fashionable trend. Digital solid prints are favored by public. So here’s where the situation currently stands with regards to the 3D printer:
At the end of last semester, leading up to finals week, the stepper motors still weren’t rotating properly (which had been the major issue since late March) - they just vibrated angrily. In addition, while testing the extruder, the material holding up the extruder began to creep due to the heat, and the extruder head began to droop - then the epoxy holding the extruder barrel to its mount failed, causing the barrel to fall out. Somehow the thermistor leads shorted out and melted off.
Fast forward to yesterday - Marcel and I took the printer out of Metropolitan Storage, where it was living for the summer. We rolled the RepRap over on a cart, and the printer did not like the vibrations at all; by the time we got to Next the machine was out of square and everything was loose, so we’ve got our work cut out for us.
Yesterday I set up the power supply, Arduino, a stepper board, and a stepper for debugging, but so far haven’t done much work on it beyond setting it up. An interesting thing I noticed, though…the stepper board has 2 bipolar LEDs that rapidly change between red and green when the motor is stepping, and it creates an orange color. Sometimes the LEDs did weird things, like one LED stayed red and the other LED was off. Something’s not right…
On the hardware side, I got a lot of work done on the extruder. The leads going to the heating element had somehow worked themselves loose and were dangerously close to fatiguing off, so I bought some high-temperature epoxy and applied it around the leads for strain relief. Hopefully that fixes that. Also, at the end of last semester, Marcel machined a new barrel mount for the extruder (the part that had been drooping due to heat) out of aluminum. This mount has setscrews to hold the Teflon barrel in place, instead of relying on epoxy. I just hope the aluminum doesn’t steal enough heat away so that the extruder can’t melt the filament…
I still haven’t fixed the thermistor leads (by attaching new wires), but once that’s done the extruder toolhead will be all set and ready to go! Pictures will be up soon, as soon as I take them.
3d printers have so many different kinds, such as 3d color printer, digital camera printer, digital copier printer, digital photo printer, solid ink color printer and so on.
