New DIY 3D printer - The Aluminatus TrinityOne

TrinityLabs has their first 3d printer out: Aluminatus TrinityOne.

Technical specification and sales pitch from the product page:

Build Volume X:300mm, Y:300mm, Z:~300mm. Print huge objects and let your imagination soar! Don't be held back by tiny build volumes in most printers. The TrinityOne does not compromise on print quality or build size. This is a one-of-a-kind printer with no rivals in the current market. After more then a year of development and strategic partnerships we have ramped up manufacturing in order to bring these high-end, industrial-quality cartesian robotics components all together into one of the best 3d printers normal humans can afford.

This is the first 3d printer comprised of all fast 10 start, 25mm pitch leadscrews. The TrinityOne is capable of linear motion on the X and Y axis of up to 390mm/sec with the motors it ships with. SIMO linear actuators manufactured by our partners, PBC Linear (TrinityLabs co-developed them to precise specifications), are taylor made for the absolute highest quality and speed of prints. The X and Y axis on the Aluminatus TrinityOne is capable of +-0.02mm repeatability and resolution per meter of travel. Compare this to +- 0.1mm of repeatability and resolution per meter of travel on the best belt driven 3d printers on the market and you can quickly see that the TrinityOne is capable of a full order of magnitude higher accuracy and repeatability than the competition.

Repeatability is the biggest factor in the perceived quality of your printed parts. Prints from a TrinityOne printer at 0.2mm layer heights appear to be better quality than 0.1mm layer heights on most other printers because of the high repeatability that precisely aligns the layers that are laid down one after another. Giving the final prints a remarkable quality of accuracy!

The Glidescrew™ is a fusion of a leadscrew and a linear smooth rod plus a leadscrew nut and a linear bearing all in one shaft. This is what the Z axis on the TrinityOne is built with. So, from a visual appearance, the TrinityOne's Z axis looks like it only uses leadscrews and no linear smooth rod. But, underneath the hood, the Glidescrews™ provide both linear motion and linear guidance in a single shaft which reduces clutter and makes a simpler machinery with very high precision.

The TrinityOne's Z axis is capable or 0.025mm or 25micrometer layer heights! Of course with the unmatched repeatability of the X and Y leadscrew axis this is not truly needed as very high print quality is achieved with layer heights of 0.2-0.27mm that look like 0.1mm prints on other competitors printers.

Print Bed: The Aluminatus TrinityOne ships by default with a true Borosilicate print surface for the flattest, highest quality print surface available for 3d printers. It also comes with a kapton heating element that allows for printing of PLA and ABS as well as many other experimental new resins and types of plastic as they become available in filament forms. The print surface is 300mm x 300mm and has a 290mm x 290mm 24V, 200W kapton heater installed under a 300mm x 300mm aluminum heat spreader. The entire assembly is supported by a G10 and Aluminum Y platform machined for a light-weight and rigid/aligned print platform that hardly needs to be leveled. The all-metal construction of the frame and the rigid linear assemblies makes it perfectly level by default. That being said, there are 4 corner adjustable thumbscrews for getting the perfection from your print head and print bed alignment required by ultra fine layer heights.

85% Pre-assembled Kit: The TrinityOne ships as a kit but has been mostly pre-assembled and tested before it arrives at your doorstep. The estimated build time form unboxing to first print is only 1-3 hours! All of the precision-aligned linear motion assemblies are prebuilt and calibrated for you ahead of time and the PSU and Electronics as well as the wiring harness are pre-mounted to the assembled lower frame prior shipping. All there is left for you to do is to bolt together around 10 major components and then plug a few wires into their pre-made harness. There is no other 3d printer kit that you can assemble faster than this one. Also, you cannot misalign the linear axis by the very nature of their pre-assembled form factors. We ship pre-installed firmware on your electronics and provide custom tailored and tuned configuration files for the host and slicing software you run on your computer to drive the printer.

Extruder: The TrinityOne comes by default with a custom-designed extruder that uses a true planetary gear head nema17 motor with massive 334 oz-in holding torque but fast speeds of up to 118RPM. This allows for it to direct-drive 3mm filament with ease and still have very fast retraction speeds. The SIMO linear stage on the X axis can maintain up to 390mm/sec speed with up to 2.4kilos of weight on the carriage so using a bit heavier motor like this on the extruder does not affect the print speed at all. By default the TrinityOne also ships with a 0.4mm nozzle Jhead MKV-b hot end and uses a hobbled pulley made by blddk, who makes the best gripping filament hobbs on the planet. This extruder/hot end setup is nearly bullet proof and the custom guilder system makes it very easy to change filaments by just cutting off the current filament and pushing in the new color as the old one enters down into the extruder. This is easily done, even while printing, to allow for easy and precise color changes during a single print.
