Actual benefits: The Deltesian, is technically a 2 Degree of Freedom Parallel Manipulator design. Doesn’t really roll of the tongue, but it has some interesting characteristics. Like a Delta, horizontal motion is converted into vertical motion by the arms. Additionally, as the machine traverses left-right-left, the carriages move in opposite directions, which helps to cancel out the momentum transferred to the frame. This means the frame can be lighter than a similar sized Cartesian. If you look at the CR-10, it uses 2040 extrusions for it’s frame. Here 2020 extrusions suffice.
The BOM is also much simpler & cheaper than a traditional Cartesian, with 3 steppers controlling all motion. All linear motion is achieved with 3 linear rails. 90% of the non-printed parts can be found in a typical Delta kit.
It’s easier to calibrate than a Delta. You get a cartesian bed. The Y-Axis can be scaled very easily. The Y-Axis can even be swapped easily.
Ultimately, it’s an intersectional design. A design that goes sideways vs leaping forward. It does what everything else does, but in a totally different way.
@Rob_Stuart_bornity practically prints itself . So cool! It’s funny how for most printers the first couple of kg go into printing upgrades, just funny to think about a machine upgrading itself.
I clicked into the gif links and found that the print bed is 220x220, but I wasn’t able to find out the dimensions for the Z axis. Is it also going to be 220?
Also, what’s the price point of this printer? I have a tronxy xy-100 and I’m on the edge of upgrading to either this or the tronxy x3…
@Will_C the design is intended to be very modular. The one shown in the gifs has a X200 x Y400 x Z240mm capacity.
At the moment the intent is not to sell a kit, just to work on releasing the open source project. If you already have printer that can do the printed brackets, it’s ~$300-350. That’s with the double heated bed btw.
I’m working on a single bed version of the Y-Axis for a more standard 220x220 build plate with a 200x200x240 build volume.
There’s still a ways to go before the project is ready for “public” release but if you are interested in following or even contributing, the Discord is where we will be working on it: https://discord.gg/4GJpdvs
@Benjamin_Deiss Very. All the pivot points are now ball bearings, not rod ends and the dark blue |x|x| crossbrace you see in between the up arm pair keeps it in plain very nice.
Additionally, all the applied forces on the XZ Tower frame, fall within the XZ-Plane.
I have consistently made compromises with this initial design to maintain accessibility. Things like printed arms and a single rail for the bed. 2 heated beds vs a single custom one w/ custom silicone heater.
Those things will come once more people get their hands on the design and the documentation improves.
, I really like how expandable it is on the y axis, great for large low profile prints. 
great work!
