Have you tried it on you MINI ?

No.  That is my next test print.  

@charles-h13

have you had a chance to try it on the mini yet?  I have it in my basket waiting for someone else to test it. 😊

I have had good luck printing small parts with the new Prusament PC Blend on the mini. Most of the parts for the MK3S I printed on the mini except for the larger parts. I am using the stock textured sheet without any prep (no glue or anything - just clean). When I first got the printer, the sheet did not seem to hold on to PETG very well, and that kind of filament usually sticks very well to the textured plate. So my textured plate may be different than normal and yours may require glue stick to release. Also, I cannot print very large parts or parts that are very dense with PC on the mini - they warp and generally fail. I personally would recommend trying something very small first to see how well the plate holds, just in case it holds too much.

How small?  5cmx5cm?  I would use it to make hand tools and small brackets.

I did but it is a challenge.  I printed it a 270 and 110 on my MK3s and 260 and 100 on my Mini.  It did nto adhere to the mini.  I will try again this weekend.

I also like 3dxtech stuff and use this materials for my i3 (Extruder, fanshroud…):

PA6

PEEK

not so easy to print, but very tough and heat resistant.

As far as I know, the only supplier in Europe is filamentworld.de

Finally ordered some Prusament PC blend and it should be with me this weekend.

I am currently using my original textured sheet for printing PETG onto which sticks nice, actually very well until it cools then just pops off. Dosent even require an IPA wipe between prints, but I do it avery so often out of habit anyway.

This sheet is now getting towards 2 years old, but I do have a brand new TheKking Mk4, also a brand new PRUSA Textured sheet both of which have never been printed on yet.

What do you recommend?, one of the new sheets without glue stick, the original without or with gluestick?.

 

Thanks.

@chocki

I use an old sheet for ABS, ASA, and PV Blend with a glue stick.

Thanks for the quick reply Charles, so you think I might experience too much adhesion with my original 2 year old sheet if I don't use a gluestick. ?

I have and it is only a matter of time.  I have roughed it up with a lot of ABS and ASA prior to PC Blend.  I hear stories of having their prints justs pop off.  Mine use to do that with some of the filaments.  Now, not so much.  It works well with PLA but that three stick too much.

I also think I might try the glue stick on the Buildtak surface (I have one of thee as well) as previously PC used to practically weld to this, but it is replaceable unlike the textured surface, I think I may have just talked myself into this approach for my own peace of mind. 😉 

Obviously I will report my results here and I'll use your tip of using the plastic razor blade to smooth a thin coating onto the surface first.

For some reason I always thought the glue stick was to help the part adhere better!, not as a release agent...

Thanks again.

Hmmmm ... I thought I posted these in this thread but I must be on drugs.  😉

I used black PC Blend to print a replacement fan shroud, my first PC Blend print, and it worked quite well.  The original (ABS I assume) had started to droop.

Before I tore the machine down I printed both the original and the remixed one in PC Blend.

I used the Kores glue stick with a draft shield and it worked quite well.

I may try the PC Blend using the Layerneer Bed Weld to see how it works as a release agent, but I'll probably do a test print on the one partially-damaged PEI side.
