Mini limitations

I was seriously considering ordering the Mini but then noticed the limitations on the material that can be used, which made me hit the pause button!

I would like to print strong and durable parts so was thinking nylon would be a material to keep in the armoury but it looks like the Mini would not be suitable.

Is this definitely the case (and could someone explain why so I get a better understanding).

Could the mini be upgraded to suit this material?

The mini looked perfect with its smaller bed size and lower cost, but it is no good if it doesn't tick some important boxes!

Thanks in advance for your help.

Regards

Mick

RE: Mini limitations

I'm wondering this as well. Temperature-wise it should be able to handle nylon just fine with a harder nozzle. Struggling to see what the problem would be.

I think you are right.  We will know after it hits the streets.

FWIW - There are lower-temp nylons such as Taulmann 230 (?) specifically designed for lower-temp printers, specifically those without all-metal hotends.

RE: Mini limitations

I would expect the biggest limitation would be with flexible filaments and the Bowman-style extruder.
Since the hotend can heat up to 280 °C, it should be hot enough to print Nylon or CPE.

I solve problems, usually with computers ......

Bowden with a geared extruder is not an issue in my experience.

RE: Mini limitations

I have recently been playing around with Taulman Bridge on my MK3. It prints quite well at 250 C. I see no reason why you could not print it on a mini. I have a feeling that this may be a little white lie.

RE: Mini limitations

I think Prusa is specifying a supported list of filaments. It's not that you can't print with others, but Prusa support will be limited to the short list.

@bobstro

This is a well reasoned take.
