Hi kadora i can cast a few more and have them available. if you need a specific head volume, let me know, currently these are design to have approx 6-6.5cc in order to achieve a static compression ratio of approx 8.5:1 (50cc for each cylinder).

if you have a 3d printer, the entire concept of "lost foam" is obsolete, since you can design your part using a CAD sw, print it and cast it... not sure how you are going to make a foam part such as a cylinder head or any other complex parts. moldlay works perfect for me, i can "burn" it in my...

i print moldlay at 185c with the bed heated to 55c-60c, it sticks to the bed very well with no deformation , although i always print with 5mm brim for better bed adhesion. the first time i took the mold out of the oven, beside the smoke (vent your kitchen, send the wife to visit a friend :-) ) i...

the main problem i came across is that Moldlay doesnt have too much information available of the web, and their example is just horrible (the broken mold part). maybe i will give lost PLA another chance, but as for now, the ability to "burn" the part in my kitchen oven and maintaining very good...

a few pics , hope you will find this informative printing the parts using Moldlay after approx 5 coats of plaster of paris, heating up in the kitchen oven, as you can see, it is clean without any residue casting this is how the parts comes out of the mold, the left one was cooled too...

i have a lot of experience with 3d printing lost wax procedure, i have tried many materials and came up with a process that is rather easy to do with some home tools. i am currently designing my own spin of a radial engine and casting some of the parts. designing the parts in a CAD software...

great work! i am trying to take a similar root designing my own radial engine. it is recommended that you take a cross cut to the wooden mock-up that you did in order to understand how close the ports actually are. since i am designing my engine in CAD, and printing it using my 3D printer, its...
