Review: Rather pricey, and finicky to print, but it works - This filament DOES NOT LIKE being printed above about 195°C (strings EVERYWHERE by 205 & chars by 220), so you have to keep your extrusion rate under tight control if you aren't using a volcano or goliath hotend. Besides that, just be wary of the shrinkage as it starts to melt (broke off some small, deep holes in my first couple investment casting attempts, leaving weird random vids in the finished pour) & be sure to keep your final burnout temperature for long enough for 100% of the filament to burn out & you can get some really nice results. ## Features - Investment Casting with PolyCast: PolyCast moldlay filament is a new 3D printing material designed for creating investment patterns in casting applications. It significantly reduces costs and lead times by eliminating the tooling process. - Polishability: Compatible with Polymaker’s Layer-Free technology, PolyCast provides superior surface quality and minimizes the need for post-processing after casting. - No Ash: PolyCast metal casting plaster 3D printing filament burns off cleanly without leaving any residue, resulting in defect-free metal parts. - Excellent Printability: PolyCast machinable wax filament is compatible with any FDM/FFF printer and offers outstanding printability. - Tangle-Free & Moisture-Free: Polymaker PolyCast filament is carefully wound to prevent tangling and is dried and vacuum-sealed in a resealable ziplock bag with a desiccant. Avoid letting go of the filament tip to prevent nodes. Use the holes on the side of the spool to help prevent this issue. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09KKZ1S1Z | | Additional Features | Investment Casting Compatibility, Clean Burn-off for Defect-free Parts | | Best Sellers Rank | #49,933 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #753 in 3D Printing Filament | | Brand | Polymaker | | Brand Name | Polymaker | | Color | 125 - 1.75mm Natural (Hex Code: #E9dfd3) | | Customer Reviews | 4.4 out of 5 stars 231 Reviews | | Item Diameter | 1.75 millimeters | | Item Weight | 0.75 kg | | Manufacturer | Polymaker | | Manufacturer Part Number | PJ03001 | | Material | PVB | | Material Type | PVB | | Model Number | PJ03001 | | Number of Items | 1 | | Number of Packs | 1 | | Special Feature | Investment Casting Compatibility, Clean Burn-off for Defect-free Parts | | Unit Count | 26.46 Ounce | ## Product Details - **Brand:** Polymaker - **Color:** 125 - 1.75mm Natural (Hex Code: #E9dfd3) - **Item Diameter:** 1.75 millimeters - **Item Weight:** 0.75 kg - **Material:** PVB ## Images ![Polymaker PolyCast PVB Filament 1.75mm Natural, 0.75KG | for Investment Casting, Casting Applications, Metal Casting Plaster, Burn Out Cleanly, Smooth Surface, 3D Printer Filament - Image 1](https://m.media-amazon.com/images/I/81w6rnGrKpL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: The title specifies 1.65 lbs. of material and the product description information specs say 2.55 lbs. So how much is being sold?** A: This material is very light. You are getting a full roll. The parts for casting are light also. I love this stuff. Having used over 50 or more rolls. Likes to drip so don't go too slow. I print at between 60 and 70 mm second. Heat the bed to about 60 C. . Have not had a nozzle blocked in months. Easy to get a first layer. Burns out 100% . Where you really need a clean burnout is in small tight areas. Heat it up to about 1200 F for a few hours. But first turn upside down at 600 F or so and let it drain out. It will drip out the bottom and burn. When you turn up and heat to 1200 it will vaporize the little that left. REX **Q: What is the melt out temperature?** A: Upside down at 600 F until it drips and stops burning and turn up and burn out at 1200 F for a few hours. **Q: Would this work with a prusa3d printer?** A: Yes, used it in a prusa i3 mk3s with no issues. Prints very well **Q: How is the odor during burnout? i tried a burnout with a random pla, but the odor was so bad it took several days to air out my shop.** A: This stuff has very little extra added to it. This will help it burn cleaner. If I put some scrap of pla in a vase and burn it--- There will be junk at bottom of vase. Repeat with this product and nothing will be at bottom. 100% clean mostly. This stuff melts at around 500 degrees F. So turn mold upside down and let drip out bottom first. It will drip and will burn as soon as it hits air. Turn back up and heat to 1200 degrees or so and get the little that's left. I have a electric oven. I push it outside for the first 30 minutes as it will smoke. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Bambu prints it great, great detail! *by B***E on February 5, 2026* Burns out great, good detail, clean prints on Bambu! ### ⭐⭐⭐⭐⭐ Rather pricey, and finicky to print, but it works *by R***R on November 27, 2023* This filament DOES NOT LIKE being printed above about 195°C (strings EVERYWHERE by 205 & chars by 220), so you have to keep your extrusion rate under tight control if you aren't using a volcano or goliath hotend.

It wasn’t as clean and high-quality surfaces as I was getting with PLA, but I could’ve probably dialed it in a little better. It burned out really well it was a noticeable difference from the PLA during the burnout, worth it but not a whole lot better than pla. I’d say if you are just doing g it for your self pla with super thin walls is fine, this is worth it if the extra quality really matters to you, keep in mind pla is 10-20$ per kg. This is 66$ per kg. ## Frequently Bought Together - Polymaker PolyCast Filament 1.75mm for Investment Casting 0.75kg, 3D Printing Filament for Lost Wax Investment Casting, Similar to Wax Filament for Metal Casting Plaster Cleanly Burn Out - Prestige ORO 5Lb Premium Jewelry Making Casting Powder Lost Wax Investment Powder for Gold, Silver ETC - DZQ Perforated Casting Flask Vacuum Casting Stainless Steel Wall Flanged with Rubber Sprue Base(3" x 4") --- ## 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.gr/products/457489078-polymaker-polycast-pvb-filament-1-75mm-natural-0-75kg-investment](https://www.desertcart.gr/products/457489078-polymaker-polycast-pvb-filament-1-75mm-natural-0-75kg-investment) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-09-09*
