Here's what I ordered around 2015 for my PB Simple Metal.
Heat transfer is fine.
Being thin is a good thing, otherwise you'd run into issues with the induction sensor probe.
That said, my Z induction probe had already failed by then and I had already replaced it with one that can trigger from further, but you should really be fine with the stock one.
Just make sure to recalibrate your Z probe after installation (both physically as well as M212), because your bed will be a tad higher and the hotend will otherwise dig into the bed.
With PEI, I barely have to "squish" that first layer, unlike with other beds.
If you squish it down like you used to you might very well need a chisel and hammer to get your parts off. Not kidding here, I had to get a 1" chisel and a deadblow to get a large print out once or twice.
I just trimmed and glued mine down on it with 3M transfer tape.
FYI: The kapton, I hear, is great for ABS, but I'm personally not using that.
PS: Prusa, I think, is also making those removeable magnetic, spring steel, PEI coated bed surfaces which sounds absolutely magical, but my plain PEI sheet is still going strong after I installed it in 2015 so I haven't looked into them too much.
The removeable spring steel magic allows you to simply flex the surface to get your stuff off it.
It's an ideal printing surface, but I havent looked into retrofitting one on a printrbot.
DM me if you need a hand, gl.
a other guy recommended me this
if that doesn't work then i will try yours :)
Amazon has them for $22. Match with one of these to attach it.
The actual product doesn't have that weird edge, it's just a flat sheet.
On Amazon. My bed size is 120mm, so a 12" sheet gives me four plates (not that I need that many though).
This is the stuff -
Another option is using a PEI sheet ([link] ). I personally use a mirror and PEI. Nice flat surface with great hold. If you don't have an IKEA near you, Home Depot has a 12 pack of mirrors for $20.
I bought the same thing for my v1:
12"x12" 0.03" PEI
(6) 12x12" 3M Adhesive Transfer Tape:
At the time there were no practical cheaper/smaller options (although the extra 3M adhesive does come in handy).
... I scored/snapped the sheet into 4 pieces, and I'm still on the first PEI sheet after like 300 hours. It still looks flawless. I only use sharp scraper blades or no tools to remove parts. If you're printing something crazy in a cold room, you can add hairspray, but for the most part, PEI has perfect adhesion on it's own.
I definitely recommend the thicker PEI (0.03"+), as it makes the MPSM bed much more rigid. I don't have to bend the aluminum bed "flat again" anymore. I dont worry about bending the bed when ripping parts off the bed, even with super high adhesion.
Clean it with alcohol, not sandpaper.
> was all scratched up due to me not being careful with getting prints off.
You probably bent your bed, it's super easy to bend back into shape by hand, just don't destroy it. On my MPSMv1 sometimes just pulling off a print can bend it upwards, and lifting a print with a blade can bend it downwards.
Put that glass back on, but a smaller sheet of glass would let you adjust the set screws. I adjust them during the first layer skirt.
My favorite MPSM bed cover is 0.03" Thick PEI (score/snap into 4 pieces) secured with 3M transfer tape
There are cheaper all-in-one PEI sticker sheets these days, but this is what I used when the MPSMv1 came out long ago, and I'm still on my first PEI square out of 4... I really wouldn't buy anything under 0.03" thick.
It needs zero cleaning and preparation, just the occasional squirt of hairspray. Parts snap off easily. Can print at lower bed temps than glass. Showing no signs of wear at all.
I use 200x200mm glass on my larger Delta printer. It's awesome, but I always keep that thing 60-80 C for printing exotic filaments. It requires more hairspray applications (every 2-4 prints) than PEI (every 20 prints), and it just looks dirtier in general.
I used this: [link]
Works like a charm. I actually like it more than the original. It has a more matte feel to it that I like a lot. I have the prusa mk2
Just in case you change your mind it has been amazing for me
I got this PEI with this adhesive.
PEI master race!
(from a previous comment of mine)
>This was the one I got, and I also got these adhesive pads to hold it to the bed. Right now the PEI is just clipped on since I wasn't sure how well it would work, but I'm planning to throw the adhesive sheet on and make it a little more permanent this weekend.
I ended up using the adhesive sheet because the middle bubbled up a little. I printed two halves of a prop that wouldn't go together smoothly because they were both concave instead of flat. I had to use one full adhesive sheet and then cut strips to fill out the rest of the bed, but that pack had 5 so it's no problem.
that's what i ordered for my printer. i have the same one, but i use simplify3D. totally worth the money.
Also known as Ultem, it can be purchased here from CSHyde. There are several options there for size and thickness. The bonus is that these sheets come with adhesive already laminated to the sheet. I believe you can also get custom sizes, although larger sheets are no problem to cut to size.
Alternatively (and probably more common), you can purchase PEI sheets here on Amazon. The recommended adhesive (transfer tape) is here, and there may be other sizes for both available on Amazon as well as wBay.
The whole idea on using PEI as a print surface is that you get good print adhesion with most common print materials. Using a heated bed with PEI works great for getting prints to stick while warm, and also pop off of the print bed fairly easily as the bed cools.
I went with the stuff from CSHyde for convenience, but I think most users here are going with the Amazon stuff (they have thicker sheets which many users prefer as it can last longer before needing replacement).
I recently stopped using blue tape and switched to PEI sheets on glass. I'll never go back. I think this would be a good thing for you to try, the PEI sheet releases pretty easily once cool.
PEI (Polyetherimide) Sheet, Opaque Natural, Standard Tolerance, ASTM D5205 PEI0113, 0.03" Thickness, 12" Width, 12" Length [link]
TapeCase 12" squares (pack of 6), Converted from 3M 468MP Adhesive Transfer Tape [link]
Do note I am using a rostock, but psi will work on all regardless, it's also acetone resistant, so you could clean really easily
Here you go
I use a sheet of 0.03" PEI stock on a glass bed with 3M 468MP Adhesive Transfer Tape.
Works well with PLA, ABS and PETG, and is easier to maintain then BuildTak, less messy then Hairspray or glue.
PEI 12x12 $16.70/sheet
adhesive sheets 6-pack $17.58 ($2.93/sheet)
lulzbot is ripping you off for that PEI.
This is what I've ordered:
Here is the version I've used, for your reference.
I bought this one:
I built a 13x13 corexy and put a 12x12 bed on it (because it's easy to buy 12x12 mirror tiles and 12x12 heated bed and 12x12 PEI).
I've used their ABS, PLA and PETG with success on the i3.
If you don't mind a recommendation - PEI board - buy one, don't have to worry about abs slurry, painters tape, etc. Will make your first experience a TON better. Here are a couple URLs to what I've used successfully on the i3.
adhesive tape -
The only reliable source I've found at the moment is Amazon. That said; I'm in Australia so options are limited :-)
I know that Amazon sells it (here), but not sure about UK shipping. It is also known by the trade name "ultem" and shouldn't be too hard to find.
I got these links from another post somewhere and bought them. They seem to be doing the job. I heat the bed up to 60-70C. A glue stick is needed when the surface area to height ratio is small. Otherwise, nothing needed. So far I've only printed PLA.
One issue I have is the build surface being a little bowed when I put it down (One side has some extra height to it). It's not too bad, but I'm trying to flatten it out.
Picked up a 12 x 12 inch piece from Amazon
I've had trouble finding any places that can supply it pre-cut in small quantities (even under 100 sheets).
Nah. This one - [link]
Glued on with this -
^That's ^why ^I'm ^here, ^I ^don't ^judge ^you. ^PM ^/u/xl0 ^if ^I'm ^causing ^any ^trouble. ^WUT?
PEI. Get PEI. A thousand times over.
And 3m sheet adhesive -
I used this guide for auto-bed leveling:
and this PEI sheet from Amazon.
For the PEI sheet, most people like to use 3M adhesive to secure it to a piece of glass. I opted to use paperclips to hold it down, and it's worked great so far. These two mods are an absolute must do in my opinion.
Get a sheet of PEI and never look back. Sorry. Was a lot vague.
PEI sheet, + 3M glue sheet = never mess with your bed again.
