The title specifies 1.65 lbs. of material and the product description information specs say 2.55 lbs. So how much is being sold?

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

What is the melt out temperature?

Upside down at 600 F until it drips and stops burning and turn up and burn out at 1200 F for a few hours.

Would this work with a prusa3d printer?

Yes, used it in a prusa i3 mk3s with no issues. Prints very well

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.

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.

Prints well with standard PLA settings but reduced head temp.

This prints exceptionally well with Qidi X-Max-3 printer. I used standard PLA settings but with lower print temperature at 200 C. Bed adhesion was great at bed temp of 60 C and final print was clean and string free. I have yet to mould and bake it out, but I have full expectation this will work as advertised. I will update the review after final casting.

Ottimo

Filamento ottimo per eseguire fusioni. Si stampa l’oggetto normalmente senza fare troppe regolazioni e successivamente è pronto per essere immerso nel calco. Si scioglie facilmente lasciando lo stampo liscio e pulito. La consiglio
