BLOOM Robotics non planar 3d printing as Formnext in Frankfurt

  1. 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.

  2. 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.

  3. 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

  4. 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.

  5. 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.

  6. 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?

  7. 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.

  8. CAM software for substractive manufacturing can already do 5+ axis for quite a while. Additive isn't that much different.

  9. 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.

  10. The two main dedicated robot 3DP slicers in the market at the minute are made by Adaxis and AiBuild. Both fantastic companies and people

  11. 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.

  12. 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.

  13. 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.

  14. 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

  15. 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!

  16. It's neat, but I feel like there are way too many drawbacks. Some are mentioned in other comments.

  17. 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 .

  18. 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
