Slicers and Print Speeds

[Gambo]

Yes holes in flat horizontal surfaces are usually OK but holes in vertical surfaces often distort if they are more than a few mm in dia. when designing a part for printing it is a good idea to work out the orientation you will be using for printing and using that a guide for placement of holes. 3D printing doesn't do overhangs well and so sometimes it is necessary to print a piece in more than one part with different orientations -just remember at the design stage to build in registers for joins between each part.
Almost all the polymers can be securely stuck together with one or the other specialist "superglues".

Usually I am not doing parts that are overly precise. I find that a 1cm test cube gives a size of about 10.03 to 10.08 cm on a side, the "shorter" dimension being in the vertical. I do think I am seeing some type of relationship between speed, temperature and "sag" however--so I expect if I can get that under control it will make things closers. I guess the one thing that is tricky about speed--is that it can be "too slow". That apparently gets into all types of dogma regarding cooling fan speed etc-. If I was running 100 parts maybe worth the time, but for one offs I am trying to get the best compromise.Thanksfritz
