A Crazy Way to Add Intricate Color to 3-D Printed Creations

A couple Chinese students at Columbia just invented a process that coast 3D-printed objects with detailed textures, allowing for incredibly lifelike "paint jobs" that are completely automated. Imagine this for manufacturing. Not only can you order a custom 3D-printed lamp sized precisely f...

Can M3D Survive?

With what we have experience from the Micro campaign and the recent status of 3D printer industry in general, do we think that M3D can survive as a company to continue making the Micro and other future products after the delivery of all KS rewards?

Re: A closer look at the Micro

good Japanese :lol: The question is, whether any mods on the micro are worth the money... How much do you want invest in a $300 printer? You may want to tell how much you want to spend to make a $300 printer to be able to work well for one or two years instead of just a couple of months or even wee...

Re: A closer look at the Micro

I do believe that some of issues we saw are related to the motors. As this motor is designed for totally different devices than 3D printers, there is very little QA for gears accuracy. Most of attention is on the output torque rather than things such as backlash. The specs from most manufacturers of...

Re: A closer look at the Micro

Is it the time to do some HW hacking? :D Go for it and get it started :twisted: One possibility is to replace those 28BYJ-48s with some good Japanese or US made geared PM steppers that deploy the metal gear train and high quality bearings. http://www.hansen-motor.com/product/stepper/Series119-2-3_S...

Re: A closer look at the Micro

... ...The motors have 4 wires so I'm quite sure they are steppers ;-) Yes, someone found that also. He even spotted the driver ships that indicate four bipolar steppers. But they somehow don't "sound" like steppers. Maybe it is a different kind of stepper than more common NEMA ones? Hmm,...

Re: A closer look at the Micro

.... the fan slows down after enabling the heater... Looks like a power supply issue. The voltage drops when the heater is on. 15W total is just too small for any 3D printer. ...The motors have 4 wires so I'm quite sure they are steppers ;-) Yes, someone found that also. He even spotted the driver ...

Re: A closer look at the Micro

Have you had a closer look at its motors? Wondering if it is its motor that limits its printing speed. I believe there are two factors limiting speed: the direct extruder with it's tiny long nozzle and the auto-leveling during print The motors can move faster... Is the diameter of its nozzle 0.45mm...
