Missoula, Montana based Acuity Design has launched a Kickstarter campaign for their new fused filament 3D printer, Helix. Helix is crafted from high-end components and is feature-rich with a large build volume and dual print heads. It is more designed for professional and institutional use with a focus on versatility, durability, and precision.
"Our vision was to create an affordable, professional-level machine capable of creating short-run production parts and functional prototypes quickly and reliably." notes the team.
Here's what Helix offers:
- A large 30-liter (300mm x 300mm x 300mm) build volume with heated bed
- Dual Exact Retract Extruders
- Dual all-metal, actively cooled E3D hotends
- Machined billet aluminum x/y gantry with precision anti-backlash lead screw actuation
- Multitude of material choices including ABS, Taulman nylon, PETT, PLA, PVA, HIPS, polycarbonate
- Autonomous micro-SD card printing with ViKI panel and Azteeg X3 control board
According to the team, their innovative Exact Retract Extruders addressed and virtually eliminated the causes of print failure, slipping and stripping filament by spreading pressure on the filament over a greater area on custom-cut filament drive gears.
The most interesting is what the Helix team calls Precision Additive Fabrication Technology, or PAFT. PAFT was developed specifically to improve mechanical precision, enabling better calibration, and greatly improving reliability. PAFT starts with a precision lead screw actuated aluminum gantry, and is complimented by their Exact Retract filament feed system for powerful and precise extrusion, and a convenient tri-point bed leveling system. Helix can be operated with any of the open source printer hosts and slicers, but it will ship preconfigured for use with Repetier/Slic3r.

In true startup fashion, the team works out of a tiny office and built the beta unit in one of the partners' garage. With the money generated from the funding campaign, Acuity Design will be able to purchase necessary manufacturing equipment and move into a more suitable production space. They will also have the resources to refine multi-material printing profiles, write and assemble quality instruction manuals, and build a comprehensive website with a parts store and support forum.
Their no-compromises approach pushes Helix's price point above that of most consumer grade printers, but still well below that of the entry-level machines from larger manufacturers. The team is building 10 pre-production units - for $4,850 you can get one Helix Beta unit, assembled, calibrated, and ready to print.
The Helix Kickstarter campaign will run for 30 days. Helix shipments are slated to begin in February 2014. Find out more info here on Kickstarter.

some of the best looking prints I've seen yet from FFD. Encosure, new extruder, and z axis only bed.

I guess it depends on what you're comparing it to. Doesn't look like they're after the consumer market.

Good specs, but price really high!
