Good morning. I need to print 5 trumpet mouthpieces that I made in CAD (.stl). I saw that you can print them in PA 12 vapor smoothing, which apparently makes the surface smooth. If you can confirm that it’s not harmful to health and that it’s possible to produce (I’ve been careful about all the dimensions and thicknesses, specifically considering vapor smoothing), I’ll make the purchase immediately. I await your response. Thank you.
Sincerely, Marco
