Hands-on With The FlexyDualie 3D Printer Extruder

Flexydualie Extruder

Ever heard of the FlexyDualie extruder? It’s a new opensource dual extruder from Aleph Objects (makers of the Lulzbot and TAZ), specifically designed for printing in a hard material — and a flexible one!

[James Bruton] of XRobots just got his hands on one and a new TAZ printer, and he’s shared his thoughts. He’s using ABS plastic and Ninjaflex rubber filament to test it out. Sure you can sometimes print with Ninjaflex using a regular extruder… but get ready for headaches as it jams in your extruder guide. The FlexyDualie is specifically designed for extruding flexible filaments which results in a lot less headaches, and a lot more productivity!

In the following demonstration video, [James] shows us the awesome possibilities of printing parts in both a hard and soft material. He even goes into detail on how to setup Slic3r for multi-material STL files.

MRRF: Stuff From Lulzbot

March 17, 2014 by Brian Benchoff 8 Comments

A lot of the big names in 3D printers were at the Midwest RepRap festival showing off their wares, and one of the biggest was Lulzbot with their fabulous Taz 3 printer. This year, they were showing off a new filament, a new extruder, and tipping us off to a very cool project they’re working on.

The new products Lulzbot is carrying are Ninjaflex filament and the extruder to go with it. Ninjaflex is the stretchiest filament we’ve ever seen, with the feel of a slightly hard silicone rubber. Straight off the spool, the filament will stretch to a little less than twice its original length, and in solid, printed form its a hard yet squishy material that would be perfect for remote control tank treads, toys, and 3D printed resin molds. With all the abuse the sample parts received over the weekend, we’re going to call Ninjaflex effectively indestructible, so long as you don’t try to pull the layers apart.

Also from Lulzbot is word on the new 3D scanner they’re working on. The hardware isn’t finalized yet, but the future device will use a webcam, laser, and turntable to scan an object and turn it directly into an .STL file. Yes, that means there won’t be any point clouds or messing about with Meshlab. Lulzperson [Aeva] is working on the software that subtracts an object from its background and turns it into voxels. The scanner will be low-cost and open source, meaning no matter what the volume of the scanner will be, someone will eventually build a person-sized 3D scanner with the same software.

Videos of [Aeva] below showing off the new stuff and talking about the scanner.
