What are the limiting factors when trying to print flexible filaments with a Bowden extruder setup?

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 ...

Is it better use Nylon fillement for cold pull even if I have been using PLA?

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 ...

Humidity sensor says drybox isn't that dry - are my expectations unrealistic or is something wrong?

Track humidity graph over days (one measurement every 3 hours is fine). Be careful that polling the sensor too often may warm it up and cause inaccuracies, the temperature dependence is quite strong. ...

Do hygroscopic filaments (PVA, Nylon) absorb moisture while in a heated enclosure

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 ...

What are the limiting factors when trying to print flexible filaments with a Bowden extruder setup?

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 ...

Does a teflon insert in an E3D V6 clone limit it's useable temperature so it can't print nylon?

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 ...

Does a teflon insert in an E3D V6 clone limit it's useable temperature so it can't print nylon?

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 ...

Humidity sensor says drybox isn't that dry - are my expectations unrealistic or is something wrong?

Alright, there were some good suggestion in the comments, and I gave them a look, but I think I solved this myself. I think, after a lot more testing, that it was some combination of stratification ...

How to fix these issues with Nylon?

If you look up the hardness of Nylon with respect to ABS you will find that ABS is generally much harder. The effect of softer filament is that the teeth of the extruder feeder dig in more into the ...

How does direct drive conversion allow higher print temperatures?

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, ...

How can I improve print speed with carbon fiber nylon and an 0.4 mm nozzle?

I got a nickel plated copper meltzone extender which solved the problem. I was able to print a decent benchy with the fastest print speeds at 70 mm/s. The melt zone extender results in the same melt ...

What filament to use for outdoor high humidity, temperature, and payload?

The application doesn't look to be demanding at all from a material point of view. Operation below 40 °C and 70-90% RH is not that special. Once taken out PLA for creep, most rigid filaments would ...

How does direct drive conversion allow higher print temperatures?

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 ...

Increase hotend temperature on Monoprice Ultimate 2

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 ...

Any experience with nylon drying on heated build platform and printing on paper?

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 ...

Printing with Nylon 6,10

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 ...
