Hi, I need to print a rectangular wall-like structure. As it is too big for printer's build plate, I printed them separately in four pieces. The problem is that when I put them together to form a...

Hi, I printed a model downloaded from the internet. The raft layer was set to 2 or 3. After the print was completed, I removed the model from the coarse build plate of my Prusa i3 MK3s. Then, it...

Thanks. Just to clarify. Do you mean it is not a good idea to add any fan near the build-plate? What is cross current?

I had the toilet fan on for all 7 hours. I guess it was not fast enough to suck out the fume than generation.

Let's say we are facing the front of an enclosure, do you mean one in fan between us...

I and family members have been feeling sick for abut three days after printing PETG in a toilet for about 7 hours. I guess even with the ventilation on, printing for so many hours created a large...

Thanks. Do you have a photo to illustrate the idea? Is it better to put the fan above the printer or near the build plate?

By vent hole, do you mean just a hole?

I don't know if it is a good idea to seal the door. If I seal it and use only one fan, there is no air to go in. If I leave some gap perhaps just like a vent...

Hi, my bedroom is very small and it only has a small sliding window on the top. So, ventilation is very poor. If I build a sealed enclosure, is it better to have two fans one for air intake and one...

Hi, I got CAD files from a company. I printed out M16 screw and the nut. They should match but they don't. What is the reason?

On the surface that touches the support, I see lots of thin lines. On other surfaces, I see small grids. So I want to make the resulting model to look smooth and shinny as if they were commerical...

Here are so photos. Please advise on how to solve the issues of rugged circular edge and asymmetry between the upper and lower halves of the circle. Thanks

Hi, what is the best way to make models made of PETG to look shinny and professional?

I always use Support Everywhere. So doing this sometimes leads to undesirable results? The side view is like ______) so I guess I need support to build the lower half of the circular shape.

Thanks. After their suggestion, I printed a raft with three layers. When I removed the model, the bottom surface of the model got ripped off because it sticked to the raft too much.

Usuaully I...

A Prusa support guy suggested it as a possible way to solve the problem. What is wrong in using a raft with PETG?

Is there other way that I can solve this problem? My models usually take 7+ hours to complete. I am doing it at home with poor ventilation so I try to reduce the length of use.

Thanks. What is S3D supports? How do I get it? Due to other constraints, I cannot print it flat.

Hi, sometimes when the models are print using PETG on my Prusa i3 MK3, there is a very thin layer that is very difficult to remove (see "thin support without raft"). What caused the thin layer and...

Hi, I am using Prusa i3 MK3 and PETG. Whenever I print structures with a standing coin-like end, I have two issues: 1. The lower half of the edge is not symmetrical to the upper half. i.e. While the...

Thanks. What I found out is that if the screw hole is at the edge or corner of the bracket, sometimes it is easy for the hole to break. Any suggestion on how to avoid this issue?

Hi, I am considering aluminum frames or 3D printed frames for the RC servo motors. Where can I get aluminum frames made? If I want to 3D print, what is the recommended thickness if I use PLA or ABS...

Thanks. Could you please explain what "top noise cover" is? Any photo or drawing to illustrate what you suggested?

Thanks Roberts but the Raise3D N2+ is so big that I don't have the room to make a even bigger chamber to cover it.
The condo management also does not allow people to fool around with the installed...

Thanks for your expert opinion. Although the 3D printer dealer suggested making a hole at the back of the case and put a fan inside, the manufacturer mentioned that doing so will void the warranty...

Hello, I plan to buy a large volume 3D printer to use at home. Brand has not been determined yet but most likely Raise3D N2+, Afinia H800+ (Up Box+) or Ultimaker 3 Extended. The problem is that...
