Do I need a heated bed for printing PLA in an enclosed printer?

I am planning on building a large enclosed (Cartesian XY-Head) 3d printer. I want to keep the inital build time minimal and it is very likely I would need to build the ~50x50cm heatbed from scratch, because it doesn't exist in ebay. The enclosure…

Height of printed part is incorrect

I have a weird problem with my old 3D printer, it is a Prusa/Mendel type. When I print a 20 mm cube, X and Y are correct, Z is resulting 16 to 17 mm. I have checked the correctness of the movement on Z using the manual controls and there are no…

What type filament should I use to produce stamps?

My wife wants me to use an FFM 3d printer to make custom stamps for her to use on paper (scrap books, letters, etc.). She is convinced, however, that they will be too rigid to make good stamps. A quick google search showed ones made from PLA and…

Is the weather a problem for MDF frames?

I've acquired all the parts to build a Reprap Prusa i3 rework, the only missing part is the frame. I'm in doubt between a MDF cut (cheaper) or acrylic (more expensive), of course a cheaper one is my preferred option until I see any disadvantage on…

Using auto-bed leveling, do I need to initiate G29 before every print?

Various methods to scan the top surface exist to improve the bed adhesion to prevent prints to come loose from the bed during printing: e.g. BLTouch and clones or inductive and capacitive sensors/probes. In order, for the print head, to use this…
