So I was happily designing and 3D printing drip tips when the question came up about 'food safe' which turned out to be a good question, turns out PLA is food safe but the printing process leaves microscopic gaps which can lead to bacteria build up, so I have put them on hold while I find a solution.
I can seal them with Polyurethane spray but I am unlikely reach the entire bore, so I am looking for a dip sealant solution that won't leave too thick a coat that it affects the dimensions too much or rub off and obviously food safe.
Any ideas please?
