## Description

desertcart.com: 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 : Industrial & Scientific

Review: Only for casting - This product burned out 100% it looks like. Other Poly products like polymax and polysmooth will print so much better. But these other polys will not burn clean for casting. Polycast will burn clean. You will get ash from the others. I have used at least 10 rolls and getting the settings right is still an ongoing process. I am now using 60 degrees C, for the bed and after 5 layers going up to 75. this will keep the part stuck. When the bed cools off the part will break off. Prints well enough to get a good looking casting. You can sand the part to get lines out. Put it in polisher for a smooth finish. Using the prints for lost wax casting. If you are using for silicon casting or epoxy cast maybe use a better printing product like polymax. REX
Review: Pretty good maybe not worth it! - I found this printed pretty well. 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.

## 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.
