They aren’t releasing it in Norway yet. The weather is too beautiful there this time of year.

Well, at the moment, it doesn’t bother me much that the printer (and a hypothetical MMU) is far away. Yesterday I got a boat! Wife and cabin in the background. Kid and boat on the shore.

Just tried TPU for the first time and it prints as fast as PLA does on the Mini… :exploding_head:

A bit see through, but that might be expected with just two layers.

0.5mm thick, the gaps are 0.1. Left the bristles connected at the bottom. Hope that holds them together better.

That looks sensational! Order lead time is down to…

7-8 WEEKS! :smiling_face_with_tear:

It really is mind blowing. They just released the profile for AmazonTPU for Input Shaper today (I am using Overture, but the profile worked with the Mini as well).

If you slow down I don’t think it will be see through.

Never!

The next one was better, was the small wet stretch of TPU.

Beats a twenty-something secretary or a hundred and something thousand euro sportscar (that requires new knees just to get in and out of anyway)…

Next level mid-life crisis: buying an expensive sportscar and building a cradle-robot to help you in and out of it.

What did you change?

Nothing, with the Mini there was always a stretch of TPU that was neither in the drybox nor in the printer but in the extruder. This gets a little more wet and prints shitty. It’s just one or two layers depending on size, still annoying. It was the last bit that was in the Mini before. Now that should be a problem of the past though with the new system. I just can’t forget to unload it and shove it back into the box. :slight_smile:

My experience with TPU is that even if you dry it, the first part of the roll will be wetter. When you have printed for a while, it seems to get better on it’s own.

For me it’s exactly the opposite - or at least it was. I used to dry it in the food dehydrator, so the outer layers were quite OK, but after an hour or so the take-up of humidity from the atmosphere was noticeable.

It will be interesting to see if it will be different feeding it from the proper dryer.

Yeah, with a PTFE-tube all the way? I sometimes feel like these pseudo-scientific experiments are more similar to the lottery that proper empirical science…

The last few hundred mm is exposed from the fancy machine - before that it was out of the dryer and into the open air!

Case in point - thicker layers = stronger prints. In my very limited, very crude testing, more perimeters beats thicker layers every time, more perimeters is “stronger” than solid infill and when it gets to that - I truly believe (within reason) that if you are chasing ultimate strength from a 3d print, you are probably building it out of the wrong material in the first place! :wink:

I guess I am a bit annoying with all the posts, but I want to show the print quality again. Both prints are 0.2mm with the speed setting, the one is TPU (the cone thingy), the other one PLA.
