The print I ordered was in a flexible TPU -- not an easy material to print. I have had other prints of this material from other suppliers and the finished items have never been as perfect as I'd like. This is the context for my 3 star rating - it's a difficult job and I don't expect the same results as one would get from a hard nylon or PLA etc. This is to test a design so it functions well enough for that. The printer was friendly, communicative and offered a good TPU filament which was the hardest (98A) that I've come across. This was a welcome opportunity.
回复: Sorry to hear you weren't a 100% satisfied. I did mention the placement of the part as the support location would affect the surface finish. My understanding was that dimensional accuracy was the most important requirement this project. To improve the finish I would suggest redesigning the part for 3D printing, to reduce the need for support material and request it is printed with a smaller diameter nozzle.
