I’m not sure I can stand the tension of this run up to Saturdays release of our new model. The story so far……….<\/p>\n
For this model we are doing brass castings by printing the waxes instead of\u00a0 (1)printing a master, (2)making a silicon mould round it, (3)casting multiple waxes, (4)making a ceramic mould round the waxes, (5)burning the wax out & (6) pouring molten brass in.<\/p>\n
By supplying the waxes were only doing 4, 5 & 6<\/p>\n
A test with 3rd party printed waxes I had worked fine.<\/p>\n
So with the deadline fast approaching the printer printed through the night producing gooey masters on the build platform. From here they’re popped off into a tub of Iso-propyl Alcohol to wash of any uncured resin.<\/p>\n

<\/a>Cleaned up they look like this. They then have to be trimmed off the printed supports, packed in sets and then shipped off to the caster.<\/p>\n
