Hi there , Im involved in making spare parts for virtually any alloy steel part thats needed to be recast in low volumes . And now Ive masterd the Wax filament and its brilliant!! hard setting up at first but worth it . Here are pictures of my latest prints , a motorcycle headstock in 4 pieces then just drip some hot wax on it and weld it all together for casting !! I get the Wax Filament from Filament World here in Germany its called Moldlay ,1.75 ,so have fun stay safe all the best
