Pocket Brush

thingiverse

I admit that this item looks fairly bad when printed in TPU with the best settings I could come-up with and eventually that were used.in the photo shown here. You can see lots of stringing, the individual layers are visible and give it a rough finished texture, the individual small cylindrical posts do break-off. Even when heated over a flame to remove some of the clinging thread-thin mess, the result is poor to say the least. Not one of my best accomplishments. However, it does work! Additionally, as an exercise in attempting to duplicate an existing design, I think I did fairly well as a novice. I don't expect that anyone would actually want to print this and use it without making adjustments that would render it a bit more refined and visually pleasing. In fact the item that this was modeled from is professionally designed by someone who really took care of details, is available commercially made from a rubbery material that is durable and pleasant to touch. I've found a few places where the actual original brush is affordably priced at barber shops and hair care web sites. Still as my attempt at replicating a real object and printing it in a material that is flexible, I'm pretty darned proud of this accomplishment as a first and only try. Printing: I didn't use supports. The slow speed (20mm/sec) and higher temperature (228 C) used with TPU filament is pretty standard as I just used the default settings Ultimaker Cura supplied. As an afterthought, I should have really ramped-up the exterior wall count as well as the infill percentage. Pulling the larger strings away with a tweezer after printing has finished as well as using the flame to melt away the finer strands was a must.
