After installation, it is best to keep it in an inverted state, or it can be fixed with a clamp to ensure that the soft magnetic sheet is fully attached to the printing platform.2.Please ensure spring steel is completely aligned with the magnetic base to avoid the resin entering the gap during use, which will affect the magnetic force of the soft magnet and cause the spring steel plate to fall off.3.If there are burrs on the surface of the spring steel, please use sandpaper carefully to make sure that there are no burrs before using it to prevent the burrs on the spring steel from piercing the FEP film during the printing process.4.After printing, do not excessively bend the spring steel when removing the model. After use, use alcohol or cleaning fluid to remove the residual resin on the surface.5.After using for a period of time, if the model falls off the spring steel sheet during the printing process, you can sand the spring steel sheet with sandpaper to ensure that it has sufficient adhesion.Package includes: 2 PCS spring steel build plate+ 2 PCS soft magnetic sheet Review: Best accessory for the Saturn - Best accessory you can get for the Saturn printer. So much easier than manipulating the heavy build plate. Now I only need to remove the plate when tilting it to let resin drip off more effectively. I put the plate back on the printer after 15 minutes or so then peel off the stainless steel sheet. Easy to use, wash and prints come off really easy yet they are firmly attached to the sheet until flexed. Well made and fits perfectly. Just watch your fingers when snapping it back onto the build plate! Very highly recommended. Just make sure you get the right size. Review: Fresh prints easy off - I wish these came with the printer bet thing I got easy to remove and get of fresh prints ## Features - Flexible and Magnetic Platform: The surface of the steel plate is machined by CNC drawing, which has good adsorption force to prevent the model from falling off during printing. - Robust and durable stainless steel material: The magnetic printing platform is made of high quality stainless steel material and has good elasticity. After bending and removing the model, it can be quickly returned to its original state and reused. - Size information: The size of the magnetic steel plate is 150 * 95mm, and the thickness of this platform is 2.7mm, compatible with ELEGOO Mars 3. Due to the thickness of the product itself, the printable height of the 3D printer will shrink by 2.7mm, you can print a spacer to compensate the difference. At the same time, after installing the magnetic printing platform, you will need to re-leveling the 3D printer for excellent printing results. - Unique handle design: The magnetic printing platform is equipped with a handle that makes it easy to install and remove the magnetic printing platform. - Installation Tips: First clean your build plate very well, let it dry, connect your magnet to the plate, let it sit for a while so it is fully seated, then install the spring steel plate on the magnetic base, last reset the printer's leveling settings to start printing . ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B1D9YYZ1 | | Batteries Required? | No | | Batteries included? | No | | Best Sellers Rank | 9,476 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 635 in 3D Printer Accessories | | Colour | Silver | | Customer Reviews | 4.0 4.0 out of 5 stars (897) | | Date First Available | 24 May 2022 | | Item Package Quantity | 1 | | Item Weight | 410 g | | Item model number | KYF-3D-111 | | Manufacturer | KOYOFEI | | Material | Steel | | Package Dimensions | 25 x 15.7 x 1 cm; 410 g | | Part number | KYF-3D-111 | | Size | 150x95mm | ## Product Details - **Brand:** KOYOFEI - **Colour:** Silver - **Compatible devices:** Laptop, Personal Computer - **Item weight:** 0.41 Kilograms - **Material:** Steel ## Images ![2PCS 3D Printer Platform for Elegoo Mars 3, Building Plate and Magnetic Sheet, Flexible Steel Plate Flex Bed for Elegoo Mars 3 3D Printer 150x95mm - Image 1](https://m.media-amazon.com/images/I/5150RLW-39L.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: does this work with elegoo mars pro?** A: I don't know. I would measure ur build plate **Q: what is the pulling force of the magnet?** A: Quite strong. it will snap up a pinch if you aren't careful. Using both magnetic sheets will not make the magnetic holding force stronger, it will make it weaker. **Q: Does the anycubic photon m3 plus need a spacer?** A: If you are using a magnetic build plate you need a spacer the size of the additional dimensions of the nagnet and plate **Q: will it work with the Elegoo Saturn S ?** A: As long as it is the correct size for the build plate, I have the mars 2 pro, I am not sure if the Saturn s plate is the same size, may have to compare them on elegoo site. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best accessory for the Saturn *by P***R on 30 July 2025* Best accessory you can get for the Saturn printer.

Not absolutely perfect, but good enough that if fitted correctly, the removal tab won't foul the sidewall of the resin vat. - The strength of the magnet is just right. Nice and strong; it's early days for me using this, but between this strength and the relatively small build plate, I'm fairly confident it won't suffer the lateral movement mid-print that plagues similar solutions on larger printers. - The Spring Steel Flexible plate is good. Again, not perfect, but good. The edges are not sharp, there's no evidence of burrs/similar that need to be removed. Now, the reason why it's 2 stars: - The magnetic layer is *much* too thick. Even on an otherwise completely stock printer with no other modifications, this uses up *more* than 'all the available' vertical adjustment on the build head. Annoyingly (not this product's 'fault', but it made it even harder to diagnose), for me, the z-axis calibration with a single piece of paper still worked as usual after fitment of this Flex Build Plate. The bed sensor got triggered as usual. Then, you go to print for real with the resin tank in place and the bed sensor *doesn't* get triggered. Meaning the build plate continues to grind downward, potentially damaging your screen and/or burning out your printer's motor. Not good. The problem is that the Flex Plate it uses up every last micron of adjustment. Yet, the FET in the base of the resin tank is fractionally thicker than a single sheet of A4 paper. So, the paper test makes you think all is fine, but when the Resin tank is in and filled with resin, it is fractionally too thick. The 'Fix': Twenty minutes of *very* carefully filing the holes shown in the attached image, then studiously cleaning all swarf off with alcohol, then re-assembling everything, re-calibrate and it all works. Yet, it's a pretty bad 'fix'. Whilst it now at least works: - There's still no adjustment left. Temperature changes alone could easily move this outside tolerances. - Replacing the FET with a fractionally thicker replacement FET/nFET, or using slightly heavier resin and you'd be back to it not working. - Adding a screen protector (a sensible mod and common mod on the Mini 8K) would further decrease the available Z-axis space and compound the problem. Yes, you could *further* file out the holes in the diagram above even deeper to restore more adjustment to accommodate the above, but doing so would further weaken/destabilise the vertical arms where these holes are and at least theoretically, would decrease print quality. Another alternative fix I could potentially see (but have not yet tried) would be to modify the printer's bed sensor so that it is ~1-1.5mm higher and so kicks in sooner. Request to makers of the Flex Build Plate: - Use a ~1-1.5mm thinner magnet. - Even then, warn users in the instructions and item description wherever it is for sale, that if they have also used screen protectors, etc. they might need to perform the above fix. Request to makers of the Phrozen Mini 8K: On the one hand, once users are modifying your product, all bets are off and it's on them. On the other... Wherever there is adjustment in engineering, unless there is a clear tendency to travel in one direction (opening up, or closing up); you try to make it so the adjustment ships dead centre. All popular modifications to the Mini 8K, however, decrease z-axis space. IE we can identify that have a tendency for them to 'close up' as they are modified. So, design the space for the hole I'm proposing modifying above, to be sited so there is only 25% adjustment in the direction of 'opening up', but put the other 75% adjustment available in the direction of 'opening up' (existing hole sizes would probably be fine, if this was done). This way, after the common mods are done, there will still be some adjustment available in either direction. I hope that this helps someone else and saves someone else hours of head scratching, investigation and emptying/cleaning the resin vat unnecessarily! :-) ----Update---- Rating now downgraded to one star. After only 50 hours of use... I noticed a strange bulge in one of my prints. On closer inspection, the magnetic layer was coming away from the base plate. The adhesive failed. Resin had gotten in behind it. Peeling the flex plate off, the magnetic layer came away (see photo above). Yes, I followed all the instructions and left it in a large desk vice for 72 hours to 'set' before using it. Now trying again with the second adhesive magnetic sheet; this time, leaving it for a week, before using it. If the second one fails inside of six months, they're going back. ## Frequently Bought Together - KOYOFEI 2PCS 3D Printer Platform for Elegoo Mars 3, Building Plate and Magnetic Sheet, Flexible Steel Plate Flex Bed for Elegoo Mars 3 Pro 3D Printer 150x95mm - ELEGOO Build Plate for Mars 3 Pro LCD 3D Printer, Replacement Build Platform with Anti-Slip Hexagon Socket Screws and Sandblasted Surface, Compatible with Mars 3 and Mars 3 Pro - ELEGOO 2PCS Resin Tank with Lid, Metal Resin Vat for Mars 3 and Mars 3 Pro Resin 3D Printer with PFA Release Liner Pre-Installed --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ni/products/448840380-2pcs-3d-printer-platform-for-elegoo-mars-3-building-plate](https://www.desertcart.ni/products/448840380-2pcs-3d-printer-platform-for-elegoo-mars-3-building-plate) --- *Product available on Desertcart Nicaragua* *Store origin: NI* *Last updated: 2026-04-22*
