You mentioned the contours on top of the keycap being an issue. A good fix for that is tilting the keycap forward 45 degrees in your slicer. This does require supports but the top finish looks so much better. The tilt technique combined with your filament should look very good.
- rolleiflex 6y agoI caught the same issue, from a slightly different angle. Using key caps with that much protrusion surface will render them unsanitary in a relatively short time due to dead skin deposits, which will cure and fill the ridges. It’s not great from a health point of view. From what I remember when I was doing 3D printing, an acetone cloud bath could help to achieve a more glossy, thus more sanitary finish. Incidentally glossy finish on porcelain-ware for plates, bath tubes, toilet bowls and sinks are specifically for this reason — gloss is achieved when the surface is flat to a defect rate smaller than the wavelength of visible light, which also gives bacteria and organic matter very little to hold on to.
- biggerfisch 6y agoUsually acetone doesn't work so well on the PLA the author is printing the keycaps in. There are other sprays or things you can apply to PLA for a good effect though - I'm betting any of the things used to make PLA food-safe would work here.
