Seller assumes all responsibility for this listing. Discussion in 'General Talk' started by Caleb, Jul 17, 2014. Yes, the lower ~80 degrees C working temperature limit of Delrin is a concern, as it is right on the bounds of a typical heated enclosure temperature. Perfect when additional accuracy is needed and less compression than in the Delrin is desired. Delrin is better in both compressive and flexural strength, comparable in tensile, shear and hardness as listed here: Delrin is hard and slick. Press question mark to learn the rest of the keyboard shortcuts, Ender 3 (SKR Mini E3 v1.2 + Volcano Hotend). How do they compare with Delrin wheels? It's possible the wheels will slowly creep below that temp, but at low stresses the creep rate may not matter at all. View cart for details. So my color scheme is dandelion and brown.
