Never heard of the 3D printing #speedboatrace? More info here: all3dp.com/2/3...
I pulled off a regulation #3dbenchy in 8m35s with my RatRig V-Core-3 printer! Standard consumer 3D printers usually take from 30-75 minutes to print a 3dbenchy. Though I'd probably have to slow down to about 15 min to match the quality.
(Yes, this was supposed to be a #shorts video but I forgot to edit in portrait mode, whoops)
This is not even close to a record (which is closer to 4min). Getting under 10min is just a benchmark for having a tightly tuned printer and knowing how to get it up to these speeds without the machine destroying itself. And it's also pretty fun to watch! I don't really plan to try to go faster as I'm worried about premature wear on this printer I have spent a lot of time and money building (like 50 hrs + ~$2k)
Check out the following videos for more info about the printer:

Part 2 - RatRig V-Core-3 The rest: [TBD]
Print Settings:
* Speed: 325 mm/s
* Accel: 20,000 mm/s^2 (this is where the 0-60mph-in-1.4s text comes from)
* Square Corner Vel: 20 mm/s
* Filament: Polymaker ASA filament @ 280C nozzle (ASA is very similar to ABS)
* Flow rate: 41 mm^3/s
Printer Specs:
* RatRig V-Core-3.1 (400mm)
* Extruder: Orbiter 2.0
* Hotend: Phaetus Rapido UHF with 0.4mm volcano nozzle

Great work! Super quick

@ObsessiveEngineering Год назад

Thanks! Some in the RatRig community go faster, but I'm worried about the thing shaking itself apart 😅. It was a fun challenge, now I think I'll give this poor machine a break...

@ObsessiveEngineering Год назад

FYI - I'm not claiming to set any records here! I set a goal to beat 10 minutes and I did. This is probably the equivalent of running a 6-minute-mile -- most people can't do it, but there's also plenty of people who can do way better. The current #speedboatrace record is around 4 minutes! I will show off a bit more of the #speedboatrace journey in my next RatRig build video.

Me neither! Sweet!

Awesome. We're getting ever closer to the goal of instant prints.

Very nice

Hello great video! Where can i find the stl for those nozzle fan ducts? :D

@ObsessiveEngineering 9 месяцев назад

That's all part of the EVA3 hotend assembly. The STLs are from the main EVA website, and also included in the main RatRig STL repo. Here's a link to the EVA website: main.eva-3d.page/heat_insert/ (it's under the "Bottoms" section). But to be clear, you don't just print the ducts by themselves, it's part of the modular hotend assembly. I have a video about it here, if you want more information: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-igVRiMfMNXE.html

What spring steel sheet do you run. Looking for a smooth for my 400

@ObsessiveEngineering Год назад

I know! I'm so annoyed RatRig stopped selling smooth 410mm PEI sheets. This one came with my ratrig kit about a year ago, but they don't seem to stock them anymore. I did recently make a new smooth plate with a 1 mm thick piece of PEI, cut it down to size, and used 468MP adhesive to attach it to a cheap textured plate from Amazon. It actually works wonderfully.

@thegmkiller1967 Год назад

@Alan Reiner the smooth with the textured on the second side doesn't make the magnet to weak to hold?

@ObsessiveEngineering Год назад

@thegmkiller1967 if I ever printed with the 1mm smooth side down, I imagine it wouldn't hold. But that would only be for printing on the textured side...I will just switch back to a stock build plate for that (the textured side of the original build plate is still in good shape, I was just trying to replace the smooth side)
