How to calculate the approximate volume of material used in 3d print?

Is there a reasonable way of approximating the volume of material used for 3D print by knowing only the STL file volume and infill percentage? Or what is the formula for calculating the exact volume and which parameters can be fixed to reasonable…

How to keep Z-axis motor from slipping when powered down

Because of the weight of my Z-axis and the relative ease of its motion, when the Z-axis motor is powered down the bed has a tendency to slip and fall down. Obviously leaving the motor powered solves this problem, but that is not ideal. I am looking…

Distortion calibration on XY plane in Repetier

I built a delta 3d printer (like a mini Kossel) and now I'm trying to calibrate it. I made all the horizontal and vertical bars myself with wood and I bought angle joints (between bars) made with 3D printed ABS. It passes all tests in Z correction…

What are the costs per meter of filament for PLA, ABS and PET?

My Craftbot Plus Craftware slicer estimates cost per job based on filament prices I add as parameters. What costs per meter would you use? I created spreadsheets to calculate this for 1.75mm diameter filament and arrived at PLA = 6.6 cents per…

Good methods to clean extruder gear (hobbed) from filament pieces?

I'm using a CraftBot original to print PLA, but some of the filament has become stuck in the teeth of the extruder gear on its way into the hot end. I'm having issues with the gear becoming stuck and "clicking" instead of turning, and I suspect it…

Why does PETG require slower speed?

PLA has a heat capacity of 1.8-2.1 J/g-K, while PETG 1.1-1.3 J/g-K. This means that each gram of PLA needs more energy to heat up. I assume no "melting latent energy", since we talk about plastics. The density is about the same. Still, printing…

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…

HDPE as the body of a 3-D Printer?

I've been working on my own DIY 3-D printer recently, and I've been trying to experiment a little with different materials for the body. Someone suggested using HDPE (high-density polyethylene), since it works well on a CNC machine, which would make…

How to remove a PLA print stuck to a BuildTak sheet

BuildTak is great because the printed plastic really sticks to it, it pretty much solved all the problems I had with prints detaching from the buildplate during printing. However, it does sometimes cause the opposite problem of prints sticking too…

What is the best infill pattern for shearing strength?

For practicality sake, I need to print a design such that there will be weight hanging parellel to the layer lines. Is there an infill pattern that would be better than others at handling this? I realize that all kinds of infill will still have the…

Ender 3 Extruder First Layer Perfect But Then Starts Clicking Afterwards

All of a sudden I seem to be having a lot of issues with under extruding on my Ender 3. The bottom layer (of height 0.1 mm) prints perfectly fine. This is done at 15 mm/s speed. However, The moment the print moves to layer 2 and above (at the…

Slicer for 32 Bit Operating systems?

I currently only have access to an old, 32 bit OS and need to slice a couple things. While there are a lot of slicers around, most popular ones, for example Ultimaker Cura 4, need to run on a 64 bit operation system. What somewhat recent (late 2018,…
