Spring Steel Build Plate for Bambu Lab A1 Mini, Rainbow Confetti PEF+Galaxy PEY Double Sided Flexible Sheet, 184x184mm

Purchased for my Bambu A1-Mini. Works really well, way less expensive than a "Bambu" branded one and works as well or better. The plate is a little bit thicker than a standard plate so make sure you are levelling the bed before printing.

I don't usually leave reviews but this was the best possible thing I could've bought for my A1 mini. I got this plate so I could have a smoother finish on the bottom of my prints so gluing parts together leaves less of a seam but was surprised that all of my prints stick to the plate like a dream, even well after the plate cools down. I'll definitely be buying more!

I had a previous review here, but this is better...I have the carbon fiber and diamond patterns both. The plate thickness is very similar to the Bambu originals. I struggled to get good adhesion to both of these plate designs. I put aside the diamond (which I found marginally worse) and focussed on the carbon fiber design as I had an application need.First - you do need to disable bed position detection in Bambu studios. Lots of help online on that and really just a box to click so no big deal.The included instructions suggest adhesion problems can be overcome by moving from the recommended smooth plate selection to a textured plate selection and then if that fails to solve the problem, as a final step, modifying the g-code. I tried all of these (the g-code sounds daunting, but it isn't too bad once you do some online searching); however, none of these sorted my adhesion problems (yes - I did detergent wash the plates too - avoiding even 99% isopropyl alcohol dilutant residue).So - back to basics.After some experimentation I did have good success in getting a nice carbon fiber look bottom layer. The trick for me on my Bambu X1 Carbon (latest version @ 15 July 2024) was to make the following changes: 1) increase bottom layer thickness from 0.2 mm to 0.25 mm, 2) decrease the speed for the bottom layer perimeter from 50 to 20 mm/s, and 3) decrease the bottom layer infill speed from 105 mm/s to 20 mm/s.

I primarily print with PETG and have had great luck with the PEI sheets. I am still an advocate for liquid glue to keep parts solid to the build plate. Afterall, I run a 3D printing business, so I can't afford to have any prints come loose from the bed. But, after trying these PEI (gold) sheets, I can confidently say that I will NOT need glue when printing PETG on this build plate. Everything has been sticking really well, and letting loose as soon as the plate cools.I'm a big fan of the subtle textured surface on this build plate. Some of the textured surfaces are "too much texture". This one is just right. The smooth side is basically glass smooth, which is nice when you want it smooth. I have used glue on the smooth side (Vision Miner nano adhesive) with no issues. I haven't had any issues with the PEI surfaces themselves. I just wash with soapy water and dry. They look and function as if new. I have about 50 complex prints on this build plate so far.I would buy this again in a heartbeat.

The original build plate for my A1 would work for about 6 prints, even with me wiping the plate down between each print with denatured alcohol, the prints would stop sticking to it. Did all the usual solutions, wash scrub etc. then would work for a few more prints and then stop sticking again. Replaced it with this one and have had no issues with prints not sticking for over 150 hrs. of printing (still wiping the plate down with denatured alcohol between prints).
