I am very much interested in building my own for personal use and a fun learning experience. Where can I find the software or guides on building one of these?
Hello I just thought about building the same thing , do you think that you can share the files for it as I will like to make my own version but I do not have a lot of knowledge in code writing
it's amazing!, I hope you can share your work, if it is already open source it would be spectacular, I would love to do a job like yours, I really liked it a lot, congratulations and thank you for sharing the video
Of course. It is still a prototype though. It would need some refinement to be useful for someone else. The amount of calibration and tweaking needed to make it work good is quite daunting. The design needs to be optimized to minimize that. And I need to consult a proper mechanical engineer about my (ab)use of the bearings, they might break down after a few hundred hours use. Considering how well it prints, it might be worth the effort. I am still very surprised by the quality of the prints I pop of the bed. This kinematics actually works good!
@@boxsterpontus no i mean the weight of the extruder assembly has a pretty long lever until its finally held by the bearings on the big pulley wheels or what you call them What bearing losd are you concerned with then
@@Throneos The weight of the hotend is pretty small, it's using a bowden tube. I just measured the drop by adding a small 180g weight at the hotend, with the arm extended to max it drops only 0.1mm. The load that worries me is the static preload from how it is held together. For example the "elbows" are using two thrust bearings with a bolt through holes in the arms, nothing else. All forces holding it together is taken by the bearings
@@boxsterpontus Yes, that's what I am saying. I am sure it's fun to build and to watch it, but I see no practical use for it, other than fun, since the accuracy and the speed must be much worse than traditional design. Also not very practical considering the needed space, since it needs more space for the same print area. Never the less, I like the idea, but in my opinion, it is not suitable as a 3D printer, even if "it works". But we have different goals, YMMV.
Why do you think this takes more space.. bedslingers or any other design all have wasted space.. And if you'd wanted an idex printer you could just make another bot, keep it beside this one and boom. Truly scalable idex capability.
@@padmanabhaprasannasimha5385 If you can't figure it out then just have a look at the arms left and right movement. That is about three times (in fact more than that) as much to the actual work area. The forward and reverse movement waste is about 50% of the work area. A traditional 3D printer waste area is considerably less than that, in fact it is only about twice the work area in one direction and about 50% in the other. Never the less, this one would impress on your friends much more than a traditional 3D printer.

one of the most creative printer design i have ever seen
Man, it's amazing!
This is very neat!
Nice work,
Nice work !
I'm wondering why you removed the redondant bar from shoulder to elbow like we can see on V1. Wasn't improving the stiffness of the arm ?
What firmware do you run for this? And what kinenatic? Im very interested. I would like to talk to you in private if you want :)
If you built it upside down with the stepper motors above the centre of the build plate, couldn't you have a way bigger build area?
are blueprints available anywere? I like vvery much this printer, I'd like to make one

Tell me what is the print quality
it's amazing!, I hope you can share your work, if it is already open source it would be spectacular, I would love to do a job like yours, I really liked it a lot, congratulations and thank you for sharing the video
The software to run it was made a part of RepRap firmware, Five Bar Scara.
@@boxsterpontus Thaks, i will look taht
Hanzhen harmonic drive gear , over 30 years experience , strain wave reducer , robot joint
do you have tutorial how to make it?
Is your logo the workspace of this type of robot? :)
It sure is. The face popped up when I was playing around with different arm lengths. I call him Scaraman
@@boxsterpontus I've done hundreds of workspace analysis of the robot and never saw a face until now. Love the Scaraman haha!
Excellent work. Are you going to open source it?

@@boxsterpontus do you mean the torsional load of the extruder?
@@Throneos I don't understand what you mean. There is very little torsional load on the hotend tip in any axis if that is what you mean.
@@boxsterpontus no i mean the weight of the extruder assembly has a pretty long lever until its finally held by the bearings on the big pulley wheels or what you call them

What are the advantages with respect to a cartesian 3D printer?
Parallel robots are capable of high speed/high presition movements.
I feel like pretty much all of that could be 3D printed
But why...?
Cool design and I am sure you have fun with it, but it isn't very practical as it takes so much more space than traditional 3D printers.
It's a proof of concept, a prototype machine to test if the idea is any good. It is a good idea.
