How does Carbon3D's CLIP technology handle bridges and support material?

All of Carbon3D's marketing and demonstrations show their CLIP technology producing contiguous and bridge-free parts. Has anyone seen examples of their M1 printing something like a buckyball within a buckyball or a figurine or some other shape that…

z-axis hard to move in some areas - what could be faults, how to improve?

I have a z-axis which follows schematically the same principle as the makerbot one's (threaded rod and two leading rods with linear ball bearings carrying a level). It is from an old experimental lab doing physics or chemistry. The axis move…

FreeCAD to design moving parts

I am trying to create a mechanism with moving parts, and would like to see how it works (whether it even works) before printing it. For example, there's a servo with a bracket, and I would like to see how far can the bracket move before colliding…

Cooling fan noise when head is moving in the X axis

I have this fan model, it is a SUNON model number MF50151VX-B00U-A99 and it is a blower type. When the head is moving in the X-axis it makes noise. I think this type of fans is not suitable for rapid movement and rapid changes in directions. I…

Are 3D printed gears applicable for industrial use?

Are 3D printed gears applicable for industrial use? I want to print some gears with ABS. What will their lifespan be? How long will they last if I use them, for example, every day?

Is there a reason for the z-axis M5 drive nut to be super loose on the lead screw?

So I bought a prusa i3 kit from a company called folger tech off of ebay. I've built it and even printed out a few parts, but I noticed that a lot of noise seemed to be happening only while the x-axis motor was moving the extruder. Then I noticed if…

How fast can printer head move without damaging steppers?

Is there any risk of damaging stepper motors if I set too big travel speed? What is maximum safe travel speed? My printer is a German RepRap Neo. I currently use 120 mm/s. Is it safe to increase this value to 200 mm/s? What would my printer do if I…

What is the best method of printing joints for action figures?

I'm interested in 3D printing toy action figures, but what I don't quite know how the joints should be designed to allow flexibility. I could imagine maybe something like a screw and nut for the arms and legs that are separated with a hole in the…

3D print leans in Y-axis

I have made a custom 3D printer with RAMPS electronics. I have printed a Benchy (ship) well, but when I try to print anything with teeth (spiral vase), gears (bearing), or a circle (rocket), the Y-axis skip steps in a regular rate giving 70-60…

How to transport a 3D printer? Dismount needed?

I need to transport my FDM 3D Printer because I am moving. What are the precautions that one should take? Should I dismount the motors and axes? I would definitively unplug the electronics as far as reasonable and fix the motors to the frame so they…

Is there a lubricant that can be used for linear bearings, bronze sinter bushings and threaded rods alike?

My printer will feature LM8UU bearings/threaded rods for the z-axis and bronze sinter bushings on the x- and y-Axis. As also, but not only, written here http://reprap.org/wiki/Lubrication, I know that one should: - use machine oil for sinter…

Herringbone timing belt?

I realized while playing around with 3D printed gears that it would be easy to make a 3D printed herringbone-style timing belt and matching gears/pulleys. Would such a design have any advantages over typical GT2 timing belts used in 3D printers? I…
