Rocky Mountain RepRap Festival 2026 - RMRRF

Some more observations from me…

The first day was the busiest yet that I’ve seen, and the attendance was high.

The initial in the door rush was grabbing maker coins like it was a raffle ticket. maybe we need a coin rationing bot in future years.

The original RepRap festival was targeted at machine RepRap movement, and that’s lost concept for a lot of folks. It became “3D printer building”, and it appears to me to being morphing to “making things with 3D printers.”

I slip in RepRap phrases when talking to attendees when I think they grok what that is. I had a handfull of folks respond to “The LR4 can cut parts for itself” or “The LR4 is able to bootstrap its’ own setup.”. They’re out there, just becoming more and more rare.

I heard quite a few “oh it’s a big plotter”, plenty of surprised expressions when I’d say something like “Everything on this table, including THAT machine (Pointing to ZenXY) was made by that machine (Pointing to LR4).”

It was weird to me that there were multiple booths that brought commercial machines which were dead at the show floor. I sort of expect that in the maker tables but not at a vendor.

Maybe in some future year we bring a really wild setup. Something like a full sheet LR4 with two machines on one set of Y belts, and each machine with two cores. Or maybe a toolchanger. I think it was @srcnet who through out an idea for a pen tool changer that has been rattling around in my brain.

I think these shows will continue to grow, but the emphasis is going to be more and more on things you can make with the machine or enhancements to existing machines.

There’s increasing overlap in attendees with the other maker movements. Lots of cosplay folks, or droid builders, or crafts and arts people coming through.

There were a half dozen makerspaces that introduced themselves to me, including some that were out of state. I think a California makerspace introduced themselves to Ryan.

I still think doing an event pre-show like what we did at Nottinghack pre-SMRRF would be fun, and this year I met one of the leaders of the local Loveland, CO makerspace. Maybe that would be a thing I try to coordinate in future years.

There were a bunch of stealth marketing things I saw. For example, some folks dropped their own maker coins into our pile. Others left flyers for things. Not someone losing track of something they were holding, but people I watched float around the space ‘losing’ materials on all the tables.

Plenty of folks at the show were just wanting to network, and I think there’s a genuine networking opportunity for folks at shows like this.

I do have a couple of regrets. I didn’t have a lot of free time between SMRRF, and the issue I had with getting into my storage facility in the snowy morning on Friday meant that I gave up on taking the not-quite-finished MPR&P machine that I’ve been working on. I feel that as a personal fail and regret it’s probably a big letdown for @dkj4linux .

Aza’s tablets are great, and I used them when I could. It’s hard to use them effectively in the crush like early on opening day, but in calmer moments where we can do more focused engagement they are great.

I also regret I didn’t have time to plan and organize better, so showed up less than fully ready to roll on setup day. I ended up chasing down EMT tubing because I set the long rail for the table beside my garage in the morning snowy chaos. The team had already almost finished the LR4 build up by the time I got back from hopping between the big box stores. The orange big box had no 1" EMT in stock, so the Blue big box store came through.

I have a couple of health items to work on, the show can be tiring and we should all make sure we help each other with managing the overload / over-stress.

I was really happy to take more time with the crew after-show, this is something to focus on.
One of the kids who were with us said “Since I’m working today, I get to go to the after-party…” A good theory, but on day 2 the after party is called teardown.

I had another weird interaction where Prusa didn’t really want to say anything about INDX on Core One L, and hinted I should talk to Bondtech next door to them, where Bondtech said essentially the opposite. I wonder if there’s been a falling-out between them, or if the Core One L for some reason is proving a more difficult challenge for some reason.

I would be remiss to talk about the show and not call out Dave’s sessions around his MPCNC an carvings. There’s always a collection gathered about Dave.

Our crew works really well together, and my sense of this is that the community who stay engaged here are much the same. It was definitely true for me going to SMRRF and meeting awesome community members and also true at RMRRF.

No chance to rest, I’m back to a really busy work schedule, but will try to get going on the projects I haven’t finished. A kick-butt MPR&P, and luggage that unfurls into a travel LowRider.

Yeah, I can agree with that. I keep trying to convince any of my CNC contacts to come out as well.

100%

:+1: So we can hang out before we are burnt out and tired.

Dave’s corner…It is so amazing. Dave you are such an awesome teacher.


I think the public open doors of the show need to be shorter, so we can all hang out and talk maker to maker more. I think for a lot of use we are so burnt out from traveling and talking with such a huge crowd, it would be nice to have a little less crowd and more VIP time. Maybe have a hours of VIP public time Friday evening so we are setup early enough to talk with each other and 100-200 vip people and we are fresh and excited and can roam amongst ourselves. I think I might pitch this to Justin. Open sauce does this and it works out pretty good.

So, will there be a CNC cut, laser cut (or laser welded) division?

Can we ask for a radioisotopic thermal generator class?

Obviously I would have loved to see you bring MPR&P… though I still wonder if it really belongs with all the real V1E stuff at a show like that. But I also have marveled at the travel schedule you’ve kept and the sheer amount of stuff you’ve carried to these shows. It tuckers me out just reading about all the stuff you are doing and I’m not at all surprised that, with all the travel/planning/prep and not being able to get into your storage facility, it didn’t make it to the show. I’m not “letdown” but still honored that you see potential in it enough to build one for yourself. I hope that if/when you get a chance to play with it more, and get it to some state of “finished”, it will prove itself as “worthy” and “kick-butt” as you think it is. When you get your MPR&P build to a presentable state I’d love to see it and hear what nifty plans you might have for it.

I’ve also loved hearing about the show and am especially impressed with the full-size LR4 and those giant plots… great idea making the bed a giant whiteboard. And it’s sheer size I suspect will always draw a crowd. I also enjoyed seeing a picture of all the crew… however, I wish someone would kindly tag everyone so names can be put with faces. I recognize you, Ryan, Jeff, Jamie, and maybe a couple of others but am unclear as to who some of the other folks are.

Hope all have gotten home safely and are getting some well-earned rest.

1000%, never doubt that part. The show is way more about new ideas being tried than shilling new products from a company, at least to me.

Anyone get a picture of both the jackpot drawings on the table at once?

I didn’t. :sob:

Also, almost on the ground!!!

You are correct. Generally, it would not connect once the public started to show up. (I had somewhat better results using my phone, but it was still spotty).

On Saturday, it was pretty hopeless. I thought I got it connected once or twice, but once I got one of my carving programs running from the SD card, I noticed that the FluidTouch was not updating.

On Sunday afternoon it was much better as the crowd started to thin. It actually managed to communicate for several hours continuously.

(Note this is a JP1 which means that Ryan’s dongle could not be used since I don’t have the add-on card. )

All that said, it’s a wonderful tool and it works flawlessly at home.

I’m sure it will be an awesome looking one too! Do you have any idea what the hardware costs. I’d like to build one for my grandsons, but I can’t find any cost estimates.

The Bigtreetech one is around $179 all in, including the remote control etc., then add in filament and time and whatever extras you want to add.

There may be cheaper ways to do it, but it’s a pretty complete kit. The remote addon is $20 which is kind of bonkers, usually see that FlySky one for ~$50.

Thanks, I’ll take a look at it. Maybe Ryan will have a kit on the V1 store. I’d rather buy it from him if he does.

I just saw this on Google News. You can get a FlashForge AD5M for $140!!! That is just insane.

AliExpress is offering the Flashforge Adventure 5M 3D Printer for $140.54 with free delivery after you apply coupon code “USBS12”.

You can barely buy a stand alone extruder for that. I would assume the component manufacturers would start to drop prices to make building more enticing but if anything the prices are even higher.

It wont ship to my address… for that price it is disposable and you cant begin to build anything close to it for the money.

The good direct drive extruders are $100 some come with the hotends. Control boards are $60, motors are $60. And without extrusion or motion components or power, we could have bought a complete machine now that takes no time to configure…. I’ve built my last printer.

Same here - won’t ship to my (US) address.

I see where you can get one for $200+tax.

I guess they raised the price since the article came out yesterday. It was $200.17 delivered in my cart on AlliExpress. Still a great deal.

Amazon has the printer for $239 regularly, (free shipping if a Prime member.). It’s been that way for a year plus.
