Hi, gr5!

Thanks for the hint.

I am looking for an extremely high resolution for microfluidics application. That's why I was interested exactly in Ultimaker 2.

Other choice I have in mind is OWL MC, but unfortunately I could not find any bussiness/private owner offering printing services at these resolutions online.

So if you have any info, would appreciate

Thanks again!

On 3dhubs you can specify UM2.

Very very few people out there (but the number is going to grow quick I think) have .25mm nozzles on their ultimaker. That is what will give you better resolution - smaller nozzles.

gr5, Makes sense.

What would be your estimate of the xy resolution with the 0.4 mm nozzle? How about 0.25 mm one?

 

[gr5 2,172]

If you have a .4mm nozzle it has a radius of curvature of .2mm (.4 is diameter, .2 is therefore radius - if you are already lost you should just go think about the nature of circles some more before continuing).

So if you print say a cube, the 4 vertical corners will have (in theory - and pretty close in practice also) a roundness or a curvature with radius .2mm. However *inside* corners in theory can be perfect. So when printing fine details the bumps or convex portions will be rounded or blurred a bit by that .2mm radius. It's hard to say the *limit* of resolution is .2mm as it can definitely show details that are smaller than .2mm but that's a good basic rule of thumb: "a .4mm nozzle lets you print an accuracy of about .2mm".

A .3mm nozzle therefore down to .15mm and so on.

These smaller nozzles take a crazy long time to print anything larger than a pea. Typically 8X slower so a 20 hour print now suddenly takes a week to print! Or a 4 hour print takes over a day to print now.
