Hi, i was just wondering what would be the minumum printable hole size allowed in full colour sandstone that wolud be printable excluding the escape holes ?...say if i made a couple of 3mm holes to thread something like a piece of string through to make a pendant ?...
0.9 mm. This is the minimum clearance required before parts start to fuse together so it would apply to holes as well, I would infer. You can go as narrow as 0.4 mm for engravings, but that only allows for 0.4 mm deep.
