As a user of an UM3E, which uses Bowden tubes and has TPU as an available material, I can tell you that the kinking issues can be alleviated or downright avoided. I've printed quite a few things with the Ultimaker-brand TPU 95, and never had problems with kinking in the tube. Ultimaker uses 2.85 mm filament, with Bowden tubes adapted for those and a rear ...

Nylon holds better when pulled, PLA may snap. Also it can grab particles around it, but it keeps low friction so the force you use to pull goes to detaching the dirt instead of rubbing against the walls. By getting solid and by maintaining strength at higher temperatures, you can pull when it's hotter (with PLA you should pull at what? 40 °C?) and by being ...

The concept that relative humidity decreases with an air temperature increase runs consistent with the concept of using a food dehydrator to purge moisture from filament spools. As the filament heats up, energy is imparted to the water molecules within. The dryer air around the spool will accept the moisture and "distribute" it to the environment. ...

To also validate the first answer, I have been printing with TPU95A for a number of years and it has been one of the most reliable materials to use. The strength of the product alongside the flex makes it a test and production based outcome with fewer issues. My printer for the most part of this experience was the Ultimaker 2+ that has a similar set up to ...

There are many types of heatbreak clones. In cour case, your clone effectively turns your hotend into an e3d Lite6, not an all-metal e3d v6. To function properly, the PTFE liner needs to butt against the nozzle or you will quickly develop leak and clog issues. This means, handle it like a Lite6, which has a max of 245 °C listed, but under usual operation ...

It depends how deep it goes. If the teflon goes into the hotend then yes, it will limit the temperature end. But: the teflon may just be something that ends somewhere in the cold side and sticks out so there is something to put into the extruder or higher up into the connector. I cam currently setting up a Slice Mosquito for a Bondtech DDX. The Mosquito is ...

Direct Drive v.s. Bowden has no relation to the maximum print temperature. What determines the maximum print temperature is the design of the hotend itself. There are "all-metal" designs, where the PTFE tube (Bowden or not) stops in the cold zone and the heatbreak and all other components that get hot are fully made of metal. Other hotend designs ...

Bowden tubes extending to the nozzle to make a seal will damage the Teflon (PTFE) tube if exceeding 250°C for an extended time. An all-metal hotend for a Bowden would have either the nozzle sealed against the heatbreak or an integrated nozzle and heatbreak. Then the Bowden tube would attach with a minimum gape with either the heatbreak or heatsink. Note: ...

You could CAD a 1 layer thick cylinder, and add it to your print and place it around your object. You can create any number of cylindrical shells that way...

Ok, first of all you need to understand why the limit is given at 250 °C: that's when the hotend design chosen by the Monoprice starts to destroy its PETG liner. To print hotter, you'd need an unlined hotend, which means you'd need a proper all metal hotend. A proper all metal hodend is a tradeoff, not an upgrade: you sacrifice some ease of printing and risk ...

240°C, lots of cooling. See Material Specification Print Sheet - Taulmann 618 Nylon.

Heating spools on the bed can be an option, but it seems inefficient to me: you lose a lot of heat and an oven would save quite some energy. Also, I wonder whether the open air will reduce the effectiveness even more, since the outer parts and the top of the spool will be colder.

Based on the information from a Quorra question about what the difference between Nylon 6,10 and Nylon 6,6 is and a ULprospector article, we can establish: 6,6 is a smaller molecule than 6,10. Base materials are different - hexamethylene diamine and adipic acid (6,6) compared to hexamethylene diamine and sebacic acid (6,10) 6,6 has a stronger tensile and ...
