Re: DIY tech shop defective hotends - 11 years ago
QuoteNewPerfectionit works far better than just wrapping the whole thing in Kapton tape like most people do and leaving air gaps everywhere. The smart ones fix the tolerance issues before wrapping in kapton so air gaps aren't an issue. Furnace cement and RTV silicone just make it look like way too much of a mess and your hotend look like it was assembled with trash.by TedMilker - General
Re: DIY tech shop defective hotends - 11 years ago
Except now you're changing the argument. You're not using any of the junk you're bringing up as a "thermal compound" for your hotend. That DOWTHERM J fluid is a heat transfer medium for a closed heat pipe system, not something you stick in a hotend to improve heat transfer efficiency. It's designed to not expand and burst a copper heat pipe like what would happen if you used water(or freeze, iby TedMilker - General

QuoteA2 Coating the bore with thermal compound will improve the heat transfer, periodically replace it when it dries out. Don't do this. There is no inexpensive thermal compound that won't break down at the temps we print at. Most of the stuff you'll find is rated at no more than 100C. All you're doing is burning it, making a mess and probably making some nasty fumes.by TedMilker - General

Quoteajmartin Any Idea where I could find someone I could PAY to make this simple file for me? I use Cubify Design so I don't know how that compares to Invent but it looks like you'd create two parts. The first part would be the outer edge of the ellipse. The second part would be the internal mesh. You can use Linear Pattern'd rectangles to create the internal mesh. Then you'd use a Booleanby TedMilker - General
