The popular LulzBot TAZ Dual Extruder v3.1 was re-engineered with a focus on improving air flow at the heat sink for greater efficiency when printing. The Dual Extruder v3.1 enables 3D printing complex geometry that would normally require time spent removing same-material supports with a risk of breaking your print and almost always leaving evidence of the support in imperfect bottom surfaces. With water-soluble supports like PVA, let the water do the work and enjoy clean and accurate bottom surfaces.
The Dual Extruder v3.1 features a unibody heatsink and redsigned fan mount with two hot ends co-developed with E3D, makers of the ever popular line of all-metal hot ends. The precision-machined design brings the hot ends closer together, resulting in a dual extruder with no need for nozzle leveling or offset calibration. Just install the tool head and accessories, quickly flash firmware with Cura LulzBot Edition, and start printing.
The Dual Extruder v3.1 comes with everything you need to install on your LulzBot TAZ 5/6, including an extra wide wiper pad mount that enables your Dual Extruder v3.1 to work flawlessly with LulzBot self-cleaning and self-leveling technology.
The Dual Extruder v3.1 was specifically designed for 3D printing models with soluble support material, which is the primary reason LulzBot users want dual extrusion. Soluble support allows freedom of design which means better rapid prototypes and better efficiency. We have had many questions about the v3.1’s ability to do other kinds of dual extrusion printing:
Question 1: Can the LulzBot TAZ Dual Extruder v3.1 Tool Head print in two colors of the same material?
Answer: Yes, absolutely, however the print profiles built into Cura LulzBot Edition have not been optimized for multicolor printing. If multicolor printing is your goal, you may need to make modifications to the included profiles for optimal results. We have included all LulzBot supported material base profiles under the Experimental classification in Materials as a good starting point.
Question 2: Can the LulzBot TAZ Dual Extruder v3.1 Tool Head print flexible materials?
Answer: Yes, the Dual Extruder v3.1 is capable of printing flexible materials. Through our internal testing, we have found that PolyDissolve S1 and PVA stick very well to TPU’s (flexible filaments), but the profiles have not yet been fine-tuned for optimal cosmetic results. Because of this, all of our flexible material profiles have been included in the Experimental section of Cura LulzBot Edition as a starting point for making your own modifications. Printing with flexible materials is recommended for advanced users on the Dual Extruder v3.1.
Question 3: Can the LulzBot TAZ Dual Extruder v3.1 Tool Head print solid and flexible materials together?
Answer: Yes, the hardware of the Dual Extruder v3.1 is capable of printing solid and flexible material together, but the profiles have not been optimized for reliability or cosmetic results. Because of this, all of our flexible and solid material profiles are included in the Experimental section of Cura LulzBot Edition Materials, and can be used as a good starting point for making your own modifications. Printing with flexible and solid materials is recommended for advanced users on the Dual Extruder v3.1.
