SovolResin 3D Printer Flex Building Plate 2 Pack, Spring Steel Flexible Plate and Magnetic Base Platform for ELEGOO Saturn 4, Saturn 3(Ultra), Saturn 2 8K, Saturn 8K 224x129mm

I have an Elegoo Mars 2 printer and from day one have loved it, however getting the prints off the build plate can be a PIG.I have a flex plate for my FDM printer so thought I would get one for my Mars, and came across the Sovol flex plate - I already have the Sovol VATS and going by the quality of them I thought I would give the flex plate a shot.So glad I did, initially I ordered the wrong size initially but soon got that replaced.So where to start, I cleaned my entire print head in 99% IPA, then gave the print bed a good sanding to rough the surface up to assist with adhesion of the magnetic plate, after the rough up I cleaned again with IPA.I pealed the backing off the magnetic sheet, lined it up and stuck it to the build plate, I then left it on a flat surface with some weights on the top of the plate and left it over night to allow it to stick well and truly.The following day I put the steel flex plate onto the magnetic base, I had a nice little pinch on my finger where the plate snapped to the magnet so be careful.The plate is very secure on the magnetic base and doesn't want to move, however using the little tabs will come of when you want it to.I don't know if its needed or not but I do it on my FDM flex plate, but I roughed up / lightly scratched the surface in random directions with some wire wool that came with the FDM plate.REMEBER you MUST relevel the bed following the manufacturers instructions for your individual printer, in some cases you may need to add a spacer for the Z axis sensor, in regards to the Elegoo Mars 2 the sensor is not needed, just make sure you loosen the nuts fully before leveling.Once levelled I put a Solov VAT on the printer added some resin and went to print, I ended up with a grinding noise, so removed the print end and releveled, did this a few times but kept getting the grinding noise, when looking the print bed had moved so it was tilting up at the front. Strange.So this time I turned the flex plate round so the 2 little tabs were to the rear, re levelled and tried again, SUCCESS seems with the VAT in the correct place with the thumbs screws in the dimples on the VAT the print head isn't dead centre and the TABS were catching on the VAT, Tried it with the original VAT and it was the same the TABS need to be at the back of the build plate. Nice easy fix.So how did it print? apart from the relevelling I changed NO settings on the printer and set it of to print an adaptor for an Airsoft RIF, 56 minutes later and I have 2 adaptors firmly stuck to the flex plate, gave them a push (wearing gloves) and they were firmly stuck to the plate, grabbed a tab to remove the plate as as I pulled the plate off, one adaptor popped off into my hand, the other stayed on, I gave the flex plate a slight bend and the other adaptor popped off.cleaned and dried the plate and stuck it on the printer ready to go.In conclusion: very easy to installed, excellent adhesion properties for the prints, strong magnetic stick and the prints pop right off when needed, already recommended to my father who has the same printer.

Bought some for my mono 4k and they are awesome.You’ll need to make or print a spacer for the z stopper. You can find this for free online.Once that’s fitted then add this magnet and set up as normal.I no longer have to take the whole build plate off. Can just take off the spring steel and add the next one, start printing again straight away.Best upgrade I’ve broke on any of my printers. Real time saver.

135 x 80mm Size - Machine: ELEGOO MARS 2 PRODislikes first - Size, I've lost a bit of build size, but that's itOk so it was a little tricky to get the Z-Axis right until I found out the Mars 2 Pro has a sprung build platform so once the screws are loosened you can push it up into the mount (took me 3hours of fiddling with the limit switch and mount before I worked this out).Once the plate was levelled as per the Elegoo instuctions I ran the print that had previously fused all 8 adapters to the supplied OEM build plate and broken each one trying to prize/scrape/smash it off - Printed perfectly and the parts just slid off (actually only held on by resin vacuum.Next up the larger parts, oh no, they are mainly in the bottom of the tank in a compressed mess!!***** You need to increase the exposure time of the base layers!! *****Bumped the exposure up from 45 to 60 seconds on Elegoo Standard Black and ran again - PERFECTI don't even need to remove the build plate each time to get them off, I leave it in the machine.I've done a litre of Resin in 3 days....................5 Stars

This magnetic build plate works. It does the job and is suitable for the Elegoo Mars 3 Pro. HOWEVER, there are a few steps that aren't mentioned in the installation guide that you need to take in order to get it working 100%.Right off the bat, your printer will have a hard time homing because the switch that is triggered on homing is now higher up because the build plate is now thicker. You will need to print a shim (look for "magnetic build plate shim" on Printables/Thingiverse) and fit it in order for the printer to be configured correctly.The only other issue I had only showed up when attempting to print a full plate. Prints were falling off the build plate about 1cm up the print. I narrowed the problem down to the smooth surfaces of the removeable plate. The instructions say that one side is more textured that the other one so that you can choose this side if there are adhesion problems. However, both of the plates I received seemed to be exactly the same on both sides. This wasn't much of an issue that a bit of sanding cant solve but it was a tad annoying to have wasted a fair bit of resin finding this out.All in all, for the price its not bad but you do appear to get what you pay for.

If you buy one beware you'll have to constantly level and re-level all the time , constantly have to wear gloves to remove and replace, you get 2 surfaces sure, but the price is unreasonable for what it's for, an considering the constant need to level your platform is irritating, might as well buy an original platform and use that for the price of these, it's like a fiver shy of a new platform. it sticks somtimes, not all the time, but the levelling really takes the fun out of printing, and makes it 10 times more tedious. and mundane.

Haven't had a problem at all, easy to clean and use

I've had these installed on my Mars 3 and Mars 3 Pro for over a year now. I have not needed to add the shim as the spring in the build plate can easily cater for the extra thickness. These are especially great if you are printing small parts such as multi-piece miniatures and their separate head etc. as you can remove the plate and just drop it straight into the wash station which prevents any mess or loss of parts as they can't fall through the cleaners basket.
