For indoor table tennis, you definitely want the traditional gas-filled ball, engineered to detailed specs. But a slightly heavier ball that catches less wind will be great outdoors - I am sure this will make a great outdoor table tennis ball. If you coat the outside with polyester resin I bet it will bounce better.
3D Printed Ping-Pong Ball
This is a common experience with this product. Mine stopped after about 3 hours of engraving. The laser is now too weak to even engrave paper. I suspect a problem with the power control electronics. If anyone has a solution to this, please share. The software is nice but gives a lot of errors - I recommend investing a bit more in a more reliable machine.

Keep us up to date on the durability of the integrated hinge design!For "softer nose pads", stop by the local optical shop. Usually, they should have both aftermarket replacement pads which you could clip off the attachment method and adhere them to the frame, or possibly use one of the "no slip silicon nose pad" pads used to "fix" plastic frames for people with nose fitment issues. If you find a good independent optical shop, you may be able to have them fit nose pad arms to the frame (though they will need to know the material properties of your printer filament to even try). It is pretty easily done with acetate frames, but with your printed frames, it would be an experiment.Shaping over an open flame is.... risky. A hot air gun, diffused, and set at a distance is much better. Better still, put a small pan of salt on a hot plate, and set the temperature to "Just right, Goldilocks", and use that to heat the frame for bending. Normal temperatures are between 150F and 300F, but without the data on your feed stock, you should start at the low end, and work your way up. You know it was too hot, or in for too long when your frame takes on little dented textures matching the shape of salt crystals ;-) Maybe print out a test piece, and use that to calibrate your temperature before sacrificing your finished frames.
