hello from French Polynesia

Hi,

I am a 3d Computer Graphics Guy,

looking for a 3d printer.

Ultimaker2 seems to be a very good choice.

But I can't help asking this naive questions :

Does Ultimaker2 really print with a 20µ résolution ?

How come it's so better in résolution (usually 100µ)than other printers ?

Thank You

Please excuse my english and my stupid questions.

It certainly can print at that resolution, but I'm not sure it's really necessary. You can get great prints at 100 micron, or maybe a bit less - but for most things going down to 20 micron isn't going to improve things very much, and it's just going to make the print take massively longer. Many other printers can also go down lower than 100 micron - it all depends on the accuracy and stability of the z-screw system and bed leveling. But the fact that you can, doesn't mean that you should.

The smallest feature that can be resolved in the x-y plane is somewhere around 0.4mm - the diameter of the bead of plastic being extruded - so having 10 or 20 times the resolution in the Z direction is of relatively little benefit.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
