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

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

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.

Prints really well! Was able to cast complex geometries. Very little ash, if any.

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.

yet to try this stuff. but i love the concept and everything came looking as advertised. if it's no good I promise I'll be back to say so. but I suspect it's going to be great

The product prints good with the right settings The investment patterns burn out good with the right heating schedule I'm using a kiln made out of dirt and garbage.

This PLA leaves no/little ash or remains during lost PLA casting. I tried to get creative and use this with a brass pour on top of the PLA without melting it out beforehand, just to see what would happen. The PLA material remained and only the top had been melted. Don't judge, I was curious.

It’s DANGEROUS!! I just poured molten aluminum into a cat with this stuff and it exploded! Blew the sand out and boiled over!!

Sure find polymaker to be the best pla I’ve been able to find. Seems like it lasts longer and easier to work with, worth the few bucks extra.

Diese Rezension dürfte vermutlich nicht viele Interessenten finden, da wohl kaum jemand in die Situation kommt, im Ausschmelzverfahren Aluminiumteile zu gießen. Ich habe damit beruflich zu tun und kann sagen, daß mir nichts vergleichbares bekannt ist und die Möglichkeit, auf einem Filamentdrucker preiswert Prototypen zu erstellen, aus denen ohne weitere Nacharbeit Metallteile mit hervorragender Oberflächenqualität und Detailgenauigkeit entstehen, ist atemberaubend. Das Material hinterläßt nach dem Ausbrennen tatsächlich keinerlei erkennbare Rückstände, ist vergleichsweise einfach zu drucken und ist, gemessen am Ergebnis, preiswert im Wortsinn. Wer sowas braucht-kaufen!

Waste of money and a lot of money.

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
