What to do with failed/unwanted 3D prints?

The "obvious" answer is re-grinding the prints and making more filament. Unfortunately, this isn't yet a very economical or simple operation. A decent filament extruder capable of holding acceptable ...

How to recycle filament material from printed parts?

If you're more interested in the recycling and reuse aspect than the re-print aspect, you could melt all the scrap filament onto a cookie sheet or into a bar (like in a bread ban). You could then ...

"Tac Tac" sound when printing with ABS

@Ecnerwal is right: that noise you hear is the extruder not being able to push the filament, and the stepper can't push any harder. When the extruder tries to push harder than it can, it gives up, and ...

How many grams will be used in a print

You can not tell this by looking at the STL file alone, because how much material will be used depends on the print settings (obviously, printing at 100% infill will consume much more material than 10%...

How is PLA different from ABS material?

The problem is that it's almost impossible to answer the PLA/ABS question just by looking at the material characteristics as it is so dependent on the application and even the specific object you're ...

What can I use to "sand" my ABS prints?

I use nail files. They're easy to get, cheap and have different grits on either side. You can lay them flat or hold them in your hand and they have some stability making it fairly easy to sand ...

Should I consider health impact of ABS or PLA when printing cookie cutter?

If it's one-time-use, both ABS and PLA are perfectly safe for use as a cookie cutter. The "food safety" of 3D printed parts is fairly controversial. In fact, whether any particular material is ...

Raft hard to remove?

A couple things to consider: Ensure that your build plate is flat and level. An un-parallel HBP could result in the object "welding" to the raft. Turn down your nozzle temperature. It is likely that ...

Best method to make dissolvable supports?

There is no requirement for an enclosure when printing ABS. Like many things in FDM, there are improvements to be made, but there is a scale of what is possible. A heated bed is much more necessary (...

Good filament/s for heat resistance in cars

ABS, or preferably ASA which is "a better ABS", is probably your main option. ASA holds up better under UV/sunlight and is easier to print (less warping). Like ABS it should be printed with ...

What is this called and how do I avoid it? (model frees itself from support structure and warps upwards)

What is this called This is called warping. Warping of prints occurs frequently when you use a filament that shrinks. If the model would shrink uniformly, it will become smaller, like in a scaled ...
