(Presseportal openBroadcast) - If you'd like to venture into the world of flexible, tough, tactile printed parts, then you came to the correct location. Here is where you’ll discover to print flexible filament rapidly and effortlessly print the softest filament out there.

Making use of the Flexion To Print Flexible Filament

This article focuses on the best way to print flexible filament using the Flexion Extruder. When you don't already use the Flexion Extruder, then go get one particular and come back here. Suitable out of your box, Flexion produces rapidly (60mm/s), clean, void-free prints with TPU, TPE, Ninjaflex, along with other flexible filaments. Angus (aka Makersmuse) even utilizes it to test flexible filament: Assessment of Flexible Filaments (with X60!). Flexion eliminates the common problems you encounter any time you print flexible filament: jamming, buckling, and oozing. Read on to find a number of tips to optimize your settings and generate great prints with your flexible filament.

Software Settings

Here’s an instance on the extrusion settings we use using a soft TPU for example Ninjaflex (about 85 Shore A). These settings are valid for speeds up to 60mm/s. A few items to note:

The extrusion multiplier above 1.0 - when the drive roller and idler squeeze the filament, they correctly minimize the diameter with the filament. This requires extra extrusion. As you boost tension you could ought to raise extrusion too.

Extrusion width reduce than the nozzle diameter - this helps create gap-free upper layers. However, it may also make overhangs tricky. You can really need to balance these things to optimize your own prints.

Retract higher and rapidly - this keeps the nozzle from oozing and makes clean prints. Longer drive paths (Bowden drive, E3D hotend, Mk11 extruder), could require even longer retractions.

We propose that you increase outline overlap above 75% to make sure a good connection in between outlines and infill. Other settings will probably be equivalent to what you use for other materials.

Hardware Settings

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

The photo under depicts two identical prints (one nevertheless has support material attached). The print on the left was created using a perfectly-functioning Flexion extruder. The one around the suitable had a tiny hardware challenge that triggered pressure buildup and “blobbing”.

So the best way to fix this challenge?

Blobs/strings/pressure buildup - in the event the barrel (see the exploded view for element name reference) just isn't pushed all the way up in to the mounting block, then the PTFE is going to be able to float among the nip point along with the nozzle, allowing the accumulation of material among the PTFE along with the nozzle. This can be a challenge that will manifest with time. You might get some quantity of “good” prints ahead of seeing this effect. The very best way to fix it really is to disassemble your hotend, remove any material, and reassemble. Guarantee that the barrel is seated on its shoulder against the bottom of the mounting block. Make certain to tighten the nozzle when it really is at temperature to get a fantastic seal.

Bumpy surfaces/inconsistent extrusion - this could be brought on by terrible settings. Before you contemplate hardware concerns, adjust temperature and extrusion up and down. If that does not assistance, you might have an under-powered extruder motor. This can “cog” toward a stable magnetic position when it must be micro-stepping, causing visible places of over- and under-extrusion. To operate the Flexion, we advise a minimum of 250N-mm of torque. Most Nema17 motors obtain this, but some drivers usually do not deliver enough existing. This occurs most frequently on Wanhao (and comparable) printers, particularly a single batch that shipped in early 2017. To adjust present, adhere to the guide right here. You can also discover replacement motors on Amazon.

Design and style Considerations

Listed below are some rapid tips to optimize prints for flexible filament:

Keep overhangs at 40° or less

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

Use slicer-generated assistance and get rid of with side-cutters. This works superior than you might picture
