Print quality of Kossel clone for Print in Place models
Delta printers are considered to be able to be accurate printers cause of the limited weight in the head (using Bowden extruder setup). The positioning can be very accurate (limited weight, limited overshooting) and because of the limited amount of weight, the print speed can be increased.

An interesting paper has been written on a comparative study between a Cartesian and a Delta machine. The paper concludes that the Delta style printer produces "a better surface finish". However, I'm a bit skeptical as the images of the Cartesian printed part they have printed are of far less quality I can produce with 2 of my printers. Fact is that Delta machines have no Z-wobble (also called banding) that is a common problem with Prusa i3 style printers for instance.
