Topic: Insulated HotEnd is a GOOD IDEA !!!!
After upgrading my cooling fans to "DELTA 40x40x15mm AFB0412SHB 2 Pin" ($5 + $2 shipping on ebay) i got so much air blow that drove me into conclusion that my printer now "BLOWS" get it ?
Yes its noisy but very effective at bringing my E3D V5 hotend down to a freezing point.
I attempted to redesign the fan mount so it would overlap the hot end by some to shield it from blast of air but that quickly failed because some parts would blast the air straight up and from all sides allover.
So i thought: Hmmmm INSULATION ?
I used aluminum duct tape and fiberglass insulation roll piece by piece wrapped around the hotend.
The tape glue stinks as it heats up (i suspect all sorts of toxic fumes come from that tape sticky side), so clearly its not the ideal way, but i already ordered another insulation tape from ebay and will give it a go very soon.
I will also try to wrap another hotend i have (from China, but aren't they all from there ?) with that yellow tape (kapton)
Results are AMAZING !!!!!! (so far with fiberglass and alum tape)
Hotend temperature is more stable. It heats up faster.
Because i can have 2 fans blow at 100%, PLA cools down instantly making the print as perfect as it could get (with what i have)
Print quality has jumped from good to gooder !
Allot of difficult areas of the print are now getting done easier with less artifacts and nearly perfect result.
Overhangs and bridges. Open holes are not nearly as problematic as before. (not a big fan of support print)
Print speed was at 50mm/s and u could go 70 but i needed as much accuracy as i could for this part.
Slight drip at the very top (see picture) but not as bad as before.
Keep in mind that this is a 100% solid print and its not warped and has no pealed off corners anywhere. Its as straight as it should be.
