Hi, I've been working on a fine chain for production in WSF, and I feel that I'm at the limits of what the laser sintering process can cope with! The chain link below is only 4.1mm in diameter, so that the charms can thread onto it. This means that the links end loops are only 1.1mm wide. It is surprisingly strong but I'd like to increase its width by 0.1mm to make it even stronger. Problem is I'll be reducing the space between links from the accepted 0.4mm to 0.3mm. Will a clearance of 0.3mm between parts be enough to ensure they don't fuse together, has any one pushed the process this far? Let me know what you think, can I get away with it? Mark.
