The laser cutter shield that I designed come out really good in quality but a bit hard to see on the wood. It was really accurate so it even got the uneven side I couldn't fix on the cad. The laser cutter works using a laser with different heat intensities to either engrave or cut out a shape. The machine is considered to be quite accurate and with the shield I design I can say that the accuracy was really good.
The SRM-20 was also pretty good though it did chip a bit of my birds head and the wings feathers also were slightly chipped the overall product came out better than I expected. The SRM-20 unlike the laser cutter is considered to be very unstable due the vibration it still did a fair job on the bird I designed. The SRM- 20 uses a bit to carve out the programmed shape though it also has constraints with sharp edges and cannot make such cuts.
The Form lab also had better precision than what I had accounted for and did well on the teddy bear the figure is holding though the bear is quite small it quite accurate and doesn't fused into the hips as I though it would. The Form lab also uses a heating mechanism but applies it differently than the laser and is used for the resin to form the desired shape.
