The best way to Print Flexible Filament

If you want to venture in to the planet of flexible, tough, tactile printed components, then you definitely came towards the right location. Right here is where you will find out to print flexible filament quick and easily print the softest filament available on the market. Get a lot more details about print flexible filament

Utilizing the Flexion To Print Flexible Filament

This article focuses on tips on how to print flexible filament using the Flexion Extruder. In the event you don’t currently make use of the Flexion Extruder, then go get 1 and come back here. Correct out of your box, Flexion produces rapidly (60mm/s), clean, void-free prints with TPU, TPE, Ninjaflex, and other flexible filaments. Angus (aka Makersmuse) even uses it to test flexible filament: Evaluation of Flexible Filaments (with X60!). Flexion eliminates the typical problems you encounter any time you print flexible filament: jamming, buckling, and oozing. Read on to discover a few tricks to optimize your settings and produce great prints together with your flexible filament.

Computer software Settings

Here’s an example of your extrusion settings we use with a soft TPU for example Ninjaflex (about 85 Shore A). These settings are valid for speeds as much as 60mm/s. A handful of things to note:

The extrusion multiplier above 1.0 – when the drive roller and idler squeeze the filament, they effectively minimize the diameter with the filament. This needs more extrusion. As you increase tension you could really need to increase extrusion too.

Extrusion width reduced than the nozzle diameter – this aids create gap-free upper layers. Nevertheless, it can also make overhangs complicated. You may ought to balance these things to optimize your own prints.

Retract high and speedy – this keeps the nozzle from oozing and tends to make clean prints. Longer drive paths (Bowden drive, E3D hotend, Mk11 extruder), may well require even longer retractions.

We advocate that you simply raise outline overlap above 75% to make sure a good connection between outlines and infill. Other settings are going to be equivalent to what you use for other supplies.

Hardware Settings

Very first, adjust tension. Hold the filament among your fingers and load filament., then turn the adjust screw to maximize the pull-force on the filament. Most printers have a function to load filament automatically. If yours does not, then try this load/unload “print”.

The photo below depicts two identical prints (one nonetheless has help material attached). The print on the left was produced using a perfectly-functioning Flexion extruder. The 1 on the suitable had a small hardware concern that brought on pressure buildup and “blobbing”.

So the way to fix this problem?

Blobs/strings/pressure buildup – when the barrel (see the exploded view for portion name reference) is not pushed each of the way up in to the mounting block, then the PTFE might be in a position to float involving the nip point along with the nozzle, enabling the accumulation of material amongst the PTFE plus the nozzle. This can be a issue that could manifest as time passes. You might get some variety of “good” prints prior to seeing this impact. The very best way to fix it is actually to disassemble your hotend, eliminate any material, and reassemble. Ensure that the barrel is seated on its shoulder against the bottom of your mounting block. Be certain to tighten the nozzle when it is actually at temperature to acquire a great seal.

Bumpy surfaces/inconsistent extrusion – this could be brought on by terrible settings. Prior to you look at hardware problems, adjust temperature and extrusion up and down. If that doesn’t aid, you might have an under-powered extruder motor. This could “cog” toward a steady magnetic position when it must be micro-stepping, causing visible areas of over- and under-extrusion. To operate the Flexion, we advise a minimum of 250N-mm of torque. Most Nema17 motors achieve this, but some drivers usually do not provide sufficient existing. This occurs most typically on Wanhao (and similar) printers, especially one batch that shipped in early 2017. To adjust present, adhere to the guide here. You may also discover replacement motors on Amazon.

Style Considerations

Here are some fast tricks to optimize prints for flexible filament:

Keep overhangs at 40° or less

Style in peelable support wherever attainable (see Ninjaflex Assistance Material here)

Use slicer-generated help and take away with side-cutters. This functions much better than you may think about
