Have you ever needed to make a few hundred of something quickly? [Roetz 4.0] has got you covered with his massively parallel entry into the SpeedBoatRace competition.
The idea behind the SpeedBoatRace is how quickly you can print a Benchy — the little boat that is used as a test print for a 3d printer. Speeding up a print is quite tricky as it means moving the head quicker and giving layers less time to deposit and a whole other host of problems. So [Roetz] took a page out of a CPU designer’s playbook, and rather than increasing the latency, he raised the throughput. The original plan was for 20 hot ends, but due to cooling issues, that had to be reduced to 18. Perhaps even more impressive than the scale of the machine is that the only off-the-shelf parts on it are the fans for cooling. Everything else is printed or machined by [Roetz] himself. The whole run was completed in less than an hour, which technically gives him a sub 3.6 minute time per benchy, even accounting for a few that failed.
This isn’t [Roetz’s] first custom 3d printer. He turned a CMM into a 3d printer a while back that offered incredible accuracy across a large build area. Thanks [Jan Roetz] for sending this one in! Video after the break.
I think you mean DEcreasing latency
Not to be the “well actually” guy but if the requirement is “The idea behind the SpeedBoatRace is how quickly you can print a Benchy” then he didn’t print a benchy any quicker.
Not that I’m not impressed with has mastering the art of parallelization.
It depends on the rules of the competition. If it’s the print time divided by the number of benchys printed then this is faster.
Sort of like attempting to produce a baby in one month with 9 pregnant women.
Seems more like attempting to produce nine babies in nine months with nine pregnant women, all impregnated by the same man.
What if you printed parts of the boat in parallel, then snapped them together? How does that match up with the rules?
Hopefully it will now be used to print useful items.
