So I have settled on a basic #3dprinting based design for #casting a water inlet for a #toyota #4AGE engine with plaster #InvestmentCasting by PLA burnout. I have been frustrated with PVA printing of support so I went old school and sliced the part. I took advantage of the parallel layers and with only minor concessions can generate very good internal geometry. Anticipating the final mass to be 325 grams.
