- MRRF2019 was fantastic and in this video we take a look at all the awesome CoreXY 3d printers that were at the show.
MRRF2019 : 3ddistributed.com/mrrf-2019/
The Reprap movement is alive and well at #MRRF2019. While there were many amazing 3d printer builds at the Midwest Reprap Festival 2019, what caught my was the corexy 3d printer designs and builds. The core-xy motion system is my favorite machine kinematics. The belt routing path is clever and useful for 3d printer motion. For such a small grass roots event like MRRF 2019 you can find some of the best corexy 3d printers of 2019.

Rise of the E3D Toolchangers
Last year at MRRF 2018, E3D intrigued listeners as they explained their tool changer design. It wasn’t the first time that RepRap designers have implemented automatic tool changing into 3d printing technology. But E3D caught the imagination of everyone and showed us a glimpse of the future of 3d printing. The Toolchanger is an advanced 3d printer setup that allows you to have multiple print heads available but only one located onto the XY gantry. This allows you to have multiple materials and colors but keep the printer fast with the light weight motion system.
Ever since the Tool Changer presentation many designers and builders have been racing to develop their own system or E3D Tool Changer clone. Not that E3D minds, they’ll be publishing the complete design open-source on Thingiverse soon.
If you havn’t heard of the RailCore 3D Printer you should check it out. It’s pretty much the best corexy printer kit available at the moment. In addition to it’s slick design the printer uses linear rails on all three axis and has the best print quality compared to the many other designs. We had a chance to catch up with RailCore Labs and Project R3D at the show. RailCore Labs is the creator of the RailCore line of printers and Project R3D is the main manufacture of the printer and kits. The machine design is done well and there are a ecosystem of upgrade available. In addition to the crew of RailCore exhibiting at #MMRF2019, 713Maker and Mandala Rose Works were also exhibiting. The two companies manufacture all the really pretty CNC machined aluminum upgrades and parts that make up the RailCore ecosystem. The RailCore printer in image below has a custom all metal machined aluminum enclosure manufactured by 713Maker. 713Maker also manufactures other machined aluminum upgrade parts for a range of delta printers and other various printer kits that are in need for metal upgrades.
Prusa XL
Unfortunately MRRF2020 was canceled due to the Coronavirus but maybe next year we’ll get a glimpse of the Prusa Research’s project. Rumors of the next Prusa printer are surfacing and look like they’re coming out with a Prusa corexy with a 400mm build area. #MRRF2021 will be interesting once we get a preview of new community developments. We all look forward to seeing what will be next. See you next year my friends! - วิทยาศาสตร์และเทคโนโลยี
So fun to build! I stopped building CoreXY printers due to the complexity and support ability. Customers could never get their minds around the belt path.
@4:30 I'm intrigued and terrified.
"Oh whats this timestamp for? It cant be that ba- HOLY WHAT THE FUCK IS THAT!...
... I want it"
Incredible designs. A lot of great ideas.
I agree
Thank you for sharing with us.
Thanks for watching
Thanks for the video, and it was nice to meet you. The variety and quality of CoreXY (and other) machines at MRRF 2019 was amazing! On to ERRF 2019 possibly?
Yeah nice to meet you. I agree there were many corexy machines there. I think it will be the main motion system for 3d printers in a couple of years.
Exoslide! I need to talk to you about buying some of your carriages. I love the work you are doing. I want to try them out on my Workhorse Printer design.
At 9:03 this TronXY what kind of configuration is used on the belts?
The one at 4:07 doesn't use the CoreXY kinematics.
Great collection of CoreXY printers! Sad to see that they're not running them faster since they are fully capable of printing at much higher speeds.
Everyone of them seems to have had a fat overweight x carriage/extruder. Madness, the large useless lumps of metal dripping off those gantries also nearly make me cry. Its as if they were all made by Hardly Ableson owners.
Ok but like are any of these for sale or are available on the ole interweb for purchase lol?
There's a link in the description that will bring you to the blog post that covers the details.
Nice meeting you. My tall XY is the one you show starting at 5:16. It is my take on Jetguy's designs. The advantage of this arrangement is that all the mechanicals are inside the frame so it is easier to enclose. Also, the wider extrusions, 20x40 are used to stiffen the frame in the X-Y plane. Same for the X gantry plate. It makes a "T" beam so there is virtually no compliance in the direction of travel so minimize ringing. The only compliance left is in the belt and rubber dampers. My next modification will be genuine Gates 9mm belts w/o the dampers. Per a comment below, yes, these printers can make *very* fast travel moves but you can only extrude the plastic just so fast. I would like to try out a Volcano...
I would actually love to know more about this printer! I have been wanting to do a 500x500 core xy and I love how simple and clean your design is. Would you be willing to share some info on it?
It was nice meeting you Mark. I do believe that your 3d printer presentation was the highlight of the video.I probably wont make it to MRRF this year but I will be back though.
@@Iceblade065 Search in Google for Jetguy 3d printer design. There's a well written blog that someone wrote after they traveled to his house to buy a printer. Jetguy explains the 3d printer build.
All running very slowly. Are they too flexible to speed up?
Hi guys your email is not working it keeps buncing I want to make some orders please get in touch
Do you have the name or info on the last one? The plen plotter?
You can find out more about that one here : www.thingiverse.com/thing:3365456 - great stuff!
That loudness...
Awesome.
MRRF looks like such a fun event. But flying across the Atlantic and then having to drive into the middle of nowhere seems a bit too much effort.
Also a lot of people don’t seem to know how a drag chain is used correctly...
i don´t get it either. Maybe someone did it wrong and then everybody just copied it?
I understand. I live in the US and it still took me a 20 hour drive to get there.
I am proud of you, you are so great! in my city this is not (
I do believe that you can make it great. Come back and show me your good work my friend.
Were any of these printers for sale to the public?
The railcore (1:00) is for sale as a kit (open source but cheaper to buy as a kit) and is an incredible machine, you can also get it as a pre-built but if you have the time save the money and get the kit
@@MrEvanmartinez thanks for the reply. As I live in the Philippines travel to MRRF would be expensive, do you know if there is a list of exibiters for the show. I would like to contact them about the corexy printers.
@@kenkozimor8471 I am not sure about that but you can definitely try checking out some forums I'm sure people would be happy to answer your questions!
@@LenniL-ob4ll didn't say i could not afford a ticket. But took you long enough to reply. I now have 3 railcore printers running 24/7
8:50
So many complicated printers! Mine is clean, simple, elegant, scratch-built. No, I wasn't there.
Yes building 3d printers can get messy.
What is the name of the first printer shown? Looks like it has 4 interchangeable heads. Thanks!
TECHILD OpenCore, www.techildllc.com/
Too noisy, I can't understand what is being said.
Oh Voron is not there
was wondering about that too
I looked for Vorons, but didn't see any. I wanted to see the belt leveling in person.
@@jstevewhite The Filament Librarian guy had the only one I saw. Was mid print when I spoke with him.
You missed 2 Piper 2 CoreXYs, but you probably consider them "not awesome" :)
Oh crap I did get some video of that...... So much video clips to go through lol. I'm posting another video tomorrow.... I'll add it in.
So slooooooowwwww. CoreXY can run MUCH faster than what they are showing. Wonder why they scaled it back so much. BTW I prefer a cross-beam printer, much less interaction between X and Y axes. See...Ultimaker for an example (no relation). I put an open-source design of one up on OpenBuilds.com called "Dash-X". Check it out and YES it's a lot faster than the snails in this video.
Cool! I just checked out the Dash X. Looks pretty awesome. I might try building one oneday.
@@3DDistributed Sounds great, let me know if you decide to go for it. Regards.
This room alone must be using a giga-joules of energy or more. This is the one aspect people do not consider, claiming 3D printing is inexpensive.
most printers use around 50 watts
@@khaderach19 I know this is a late reply, but I can say that most of those printers shown use way more than 50 watts. Based on the type of hotends, number of steppers, size of heated beds...sure, gimicky little machines might use that much, but nobody in that room is using less than 150W power supply. My machine uses a 150W supply and a 800W AC heated bed. But, there is a gimme though. It takes more energy to heat up hotends and beds than it does to maintain that heat, especially in an insulated chamber. So you aren't using that much power all the time. A way to prevent over-charging some PSU's is to keep the steppers powered off while the bed and hotend heat up, and once they've stabilized then turn on the steppers.
All bullshit this machines. Why do you add 4 lead screw on the machine???
Can you do better? Do some research on Voron 2 gantry leveling.
