Can general purpose polystryene (not HIPS) be used for 3D printing?

High Impact PolyStyrene (HIPS) is a frequently used filament in 3D printing. It has been touted to have simular properties when printed to ABS and is especially useful for support structures (if the user has a multi-nozzle 3d Printer) as it is…

Is PLA filament conductive?

I am planing on printing something that will make contact with PCB boards. The print will be most likely to be in PLA. I don't want to fry the PCB board so I want to know if 3D printed PLA objects are conductive. I googled and found out about…

Printing Plastic Replacement Parts

On a number of occasions I've broken small plastic parts that are nearly impossible to replace but could easily be 3-D printed. The latest such mishap is the volume knob on the factory-installed radio on my car. I have little experience in 3D…

Comparative design methods for joints that will be joined together

I want to 3D-print some parts that will be later joined together along a seam. When modeling these separate parts, what are some methods that work well with 3D-printed pieces? For example, if I were doing wood working, I might choose dowel and pin…

Second layer: gaps, poor adhesion - why?

I'm seeing the following pattern on my Prusa clone: The first layer prints OK, layer adhesion to the bed is good. The second layer shows the weird gaps. On larger pieces, or with an increased feed rate, it sometimes gets so bad that parts of the…
