is PLA gasoline, diesel or chemical resistant?

can PLA be used to print out containers or other parts that are in direct contact with gasoline, diesel or other hard chemical substances? Will it start degrading when in contact with said chemicals? Should I use ABS for this?

Can anyone suggest what technology and 3D printing material is most suitable for printing of dental models?

I'm looking for a 3D printer for applications in the dental field, for printing digital dental models (not for itra-oral use parts). Resolution and finish are the main requirements that we consider necessary. Any suggestion?

How thin can I make the wall of a pipe?

For a science project, I'm 3D-printing some custom pipes and tubes to regulate the flow of gas (a combination of ethyl alcohol and water vapor) through an apparatus. They need to be pretty small, as the entire experiment is designed on a small…

Ok to shutdown printer after unloading filament, with no cool down?

With a fan cooled, all metal hotend, is there any reason to wait for the hotend to cool, before shutting down power, if the filament has been unloaded? When leaving the filament on the machine after a print, I’m normally in the habit of waiting…

Easy way to visually inspect/preview large amount of stl files (on Linux)?

I'm a beginner in 3d printing, so please bear with me. I downloaded a zip with about 100 STL files. I now want to pick one or two to print. The names of the stl files are not very helpful so I need to look at them to find the ones I want. I can open…

Is there an example of tight coupling between CAD and sliced models?

I am on the hunt for CAD packages which can perform some level of slicing as an inherent model feature, instead of either exporting to STL and then importing into the slicer (a la OnShape) or directly opening the slicer from within the software (a…

Clogging from heat creep, but only in the nozzle itself?

I have an all-metal V6 hotend clone that has worked in the past, but recently will clog very easily. I've tried the following to address it: Clean/replace the nozzle (0.4 or 0.5 mm, nozzle is hot-tightened) Ensure nozzle is tightened against the…

60 watt heater into 40 watt heatblock

This might be a dumb question, but can a 60 watt heater be used on a 40 watt unit? Simply put, I was wrong in thinking that more power was simply stuffed into the same dimensions. It extends about 5 millimeters beyond my heating block. Can it be…

Why do nearly all cheap 3D printers have a Bowden extruder?

It seems that a Bowden extruder is the most used in all cheap 3D printers by far compared to Direct Drive that is very rare under 500 USD machines. But I haven't understood the reason, since in terms of hardware a direct drive doesn't seem to have…
