The trouble with getting the price down on this is motors and encoders, and to a lesser extent the power supply. You need at least 6 motors+encodersfor the arm and 2 for the base. This is compared to 3 for any other 3d printer (Delta, core xy, etc). And the power supply needs to be beefier to handle a minimum of double the current (likely higher since the motors also have to handle the weight of the arm and holding the base at an angle.
If it solves a problem everyone has, it'll happen. I can't think of a problem I need something like this for myself, but maybe I'm just lacking imagination.
As someone who is just now getting his first acceptable prints out of a pellet extruder after about 4 weeks of constant work on it, I'm not surprised at all. They do robot arms with tools, not robot arm 3d printers, so they won't have the extruder super dialed in
Looks like a demo, possibly hasn't been set-up correctly yet. print speed might also have been set higher than should be, probably for it to be eye catching to the passersby and redditor.
I'm guess they were probably printing at a courser layer height and faster speed than what they'd normally use since this is an expo. It's not as "impressive" if it takes more than the length of the conference to print the part.
I can understand that quite fine... but the slicer behind??? Other than writing printer code, I struggle to see the workflow from CAD to Printer of complex pieces... or the slicer is super wise and can resolve most issue. Can we print in place an intricated twisted shape without supports? What about "bubbles" with needles pointing toward the center?
This is honestly a small step away from the past 15-20 years of CAM for 6+ axis machines. It's just another version of CAD/CAM software so really nothing revolutionary.
NX has multiaxis additive. You setup a file with each different printing configuration as a separate body(i.e. a hollow cylinder body and a roughly rectangular body with a hole to be screwed into). From there you do your machine setup/selection. You can then select a body and add an additive operation. You have options like matching orientation of lower layers, matching orientation of build surface, tangent/normal to a selection, handle curves with variable layer heights vs splitting curves into multiple angled sections. Whole ton of options. Once you've set everything up you need a post processor(same as with CNC machining) which converts the points/paths/process parameters into machine specific instructions.
With kinematic bed like the Ratrig has, I’d love to see some baby steps towards non-planar printing. Even just angling the platform could do wonders for overhangs and such.
I'm here too and saw that thing. 5/6 axis printers are everywhere this year... I wonder what's their selling point in particular. Didn't have time yet to ask; so much other cool stuff to see. First day and I barely made it through half of the exhibition.
Too many points of failure and sloooooooow. Also, product looks bad. There's a prototype of an extruder on an (45 degree?) angle, that accomplishes basically the same thing with vastly better results.
This kind of setup is between $100k-$200k. Something from Thermwood, who have the nicest prints and machines, will set you back $1m-$3m. When parts are often machined after for surface finish anyway, it regularly makes good commercial sense to go for a robot printer. While the usual technique is printing at 45°, there's also parts I've been able to print utilising the additional axes for more challenging parts that a restricted gantry system wouldn't be able to print without a lot more time and material
Man, you're killing me. I picked the short straw this year and had to stay to keep the lights on back in the US. The stuff my team is sending me looks so cool!
I am waiting for the times when those kinds of printers become precise, small and cheap. Those kinds of printers (not construction, but idea. I think moving bed is bad idea in general) and slicers will be a gamechanger .
That is really great, but I aspire to have a quick and fast printer or something that doesn't need infinite amount of time of cleaning and postprocessing

That’s putting a lot of faith in bed adhesion.
Pffft, it just needs more brim.
One day we’ll all have access to this technology at a reasonable price
6 axis isn't unreasonable...the slicer code is a bitch though.
you can get a normal 3d printer for $100 at microcenter then just get some stepper motors and you can make it your self

Eh.

surface looks like crap
Yeah, the layer adhesion also wasn't so good when he popped up the print from the bed. A few layers broke apart on few regions.

My guess is the backlash is garbage. Looked to be jumping around a fair hit
Looks like a demo, possibly hasn't been set-up correctly yet. print speed might also have been set higher than should be, probably for it to be eye catching to the passersby and redditor.
I don't think surface quality is the thing that's supposed to be impressive about this demonstration.

I've been doing CNC machining for 12+ years now.
CAM software for substractive manufacturing can already do 5+ axis for quite a while. Additive isn't that much different.

The two main dedicated robot 3DP slicers in the market at the minute are made by Adaxis and AiBuild. Both fantastic companies and people
I got quoted $11k for a 5 axis slicer. Was a pretty sweet slicer though.
The software was 11k? What is it called?
Those layer lines look brutal
that doesnt look leveled AT ALL!!
I really wish I didnt have Covid right now. Thats an hour drive for me and 9€ as as Student.
Oh ouch. Feel better soon!
Get better soon!
Drück dir die dir die Daumen das es kein schlimmer Verlauf wird! Gute Besserung!
Ich gene da vielleicht hin. Muss mal schauen, ob ich Zeit habe
I wonder why the head/nozzle rotates
It seems it's because of two different colors. It rotates to switch between the two.
If that is it's normal speed they probably started printing last week.
With kinematic bed like the Ratrig has, I’d love to see some baby steps towards non-planar printing. Even just angling the platform could do wonders for overhangs and such.
How many of us are seeing if we can fit this somewhere at home?
If I could afford it, I'd make it fit.
One day I'll build my home around it.
Any idea what they are saying this is for?
Is there actually any real advantage to printing this way or is it just for show.
In a planar configuration, this model is not possible to print without supports.
Probably to showcase their roboters in the first place.
Very much a gimmick but cool anyway

That’s a very thick layer! Maybe 2mm?
I can't get close enough (1,2m distance) but it looks like 1,5 - 2,0mm.
They should have staggered that seam.
Man, you're killing me. I picked the short straw this year and had to stay to keep the lights on back in the US. The stuff my team is sending me looks so cool!
Bed adhesion on point.
I don't wanna level this bed.
It's neat, but I feel like there are way too many drawbacks. Some are mentioned in other comments.
I want to go there so badly but I dont have the time
Sieht echt nice aus.
Looks like dog shit, cool idea though
This is porn.
This comment section is full of words I don’t understand.
I will take "Things I can't afford for $1000", Alex
Yeahhh... stick with 3D printing homes, thanks.
Needs to adjust his retraction.
can they
LOL, so what is this??
Man that bed needs to be leveled
What filament
Is the bed leveled ?
But why?
Please tell me about their first layer adhesion solution. I think I could benefit. ;)

Looks terrible, why print something like that on there, you can print that on a regular 3D printer.
Seems like they don’t know how to calculate constant end effector velocity. Oof
That is really great, but I aspire to have a quick and fast printer or something that doesn't need infinite amount of time of cleaning and postprocessing
Oh nooooo!
Hey kids, wanna see 18 hours worth of printing slide off the print bed?
The dreaded seam is still there
Just know, if they ask about bed leveling, we are doomed.
Lol how many times did they have to level it though???
Well that's one way of fixing your bridging issues...
I was almost impressed until they zoomed in.
Yes please. How can I get one?
Doesn't look very fast, or very good, but very, very cool.
We live in a future.
Looks cool but… why?
You have a million dollar machine and you're printing a vase.
I can finally print spaghetti in 6d
Why tho
yeah, just making a vase for my room because just because
Wow.
