Practical 3D Printing: Julia Vase (Video)

Here's a robot video that I found interesting:



Featured on http://www.robots-dreams.com I get a little bit frustrated seeing how rough the surface finish is on many of the 3-D parts posted on the Internet. I'm sure that most of the 3-D printers out there haven't been calibrated or tuned properly to produce the best parts. Working with Sublime, the creator of the Tantillus printer, I've been exploring the limits in terms of quality. The Julia Vase from Thingiverse is a good test print that can be used for comparison. http://www.thingiverse.com/thing:28123 The size was scaled to 50% of the original. Rather than depend on defaults, the critical parameters were specifically selected to produce the best, most consistent prints. In this case a layer height of 100 microns, resulted in an extrusion width of 0.5 mm, with a solid infill speed of 52.5 mm/s, perimeter speed of 62.5 mm/s, and a sparse infill speed of 75 mm/s. The part was printed in PLA from Diamond Age in New Zealand. Getting performance out of your printer that looks this good isn't easy, but is certainly worth it. Of course, I am not going to stop here. I'm always looking for new ways, techniques, or procedures that will help me improve the quality of the parts I print.
