Hello, new to both 3D printing and CNC’s so thought I’d give myself a challenge…
Started printing with mixed success but seem to be getting imperfections on the top layers of some of the parts, is this normal? and will it be okay?
Also struggling with getting some of the thinner bits seem to warp, (ie Brace Max) any advice would be great to stop this.
Thank you!!
Your image is soft, making it difficult to see if everything there is normal. The lines around the perimeter and across the surface is normal, but there may be some voids and blobing in the center of your part, which is not normal. I cannot tell for sure from this picture.
Temperature plays a big role in how the surface turns out, so you want a good match between your filament type and the temperature. If you want to check this out, there are a variety of test g-code files that print towers to allow you to evaluate your filament at different temperatures.
Temperature can also play a big role in warping. You would need to show us the warping, and also show us how the part was positioned on the build plate. Bed adheasion is a big issue with warping. Historically, bed adheasion was a bigger issue. With newer machines and new build plates, it is not as much an issue, but with a new printer, you need to get it dialed in. Take a look at the corners of your printed parts to see if they have pulled off the build plate. There are a variety of adheasion solutions, buit I don’t want to go down that road until think that is the issue.
Finally, mosture in the filiment can cause voids and blobing like what I might see in your image. I wouldn’t expect mosture to be an issue with a new printer and new filament, but if you are printing from a partially used filament roll from a friend, or if the new roll was not vaccum sealed from the factory, it is something you should look into.
If your surface finish is just normal 3D printer artifacts and not something to worry about, there are slicer settings that can reduce it or hide it. Ironing will pass the hot extruder across the surface to even things out. Fuzzy skin will create texture to hide the lines. But normal 3D printer artifacts are not an issue structurlly.
There are many people on this forum with extensive 3D printing experience. They can help you more if you provide more information:
