Never mind everyone. I imported my drawing into Tinkercad. I'm working on a drawing, drawing it in 2D, in Pixelmator Pro. I've uploaded the drawing to https://anyconv.com/jpg-to-stl-converter/ to convert it to a 3D.stl. I then open the 3D .stl. I'm drawing it in 2400dpi, then using meshlab to view the results. My question is, when I zoom in, meshlab shows the pixels on a curve. If I upload this to shapeways, will my print be smooth? How can I get rid of these jitter jags to make the 3d drawing look smooth when zooming in, so I will get a smooth print? Here's an attachment of the .stl, so you can see. Thanks for any advice.
