10 AMAZING 3D Printing Projects: Rocky Mountain RepRap Festival 2023

[@ratchetz]

I know LDO sponsored your video… but the fact that they’re gearing up to make a kit for a Positron excites me so much. I’ve wanted to make one for a while now, and a pre-set kit with a bit of support if I needed it sounds phenomenal. I’m looking forward to seeing what they come out with.

[@UNVIRUSLETALE]

Wow didn't know that, it'd amazing, I have to move in a few months to another country and it'd be a great way to bring a 3d printer with me

[@andybrice2711]

Yeah, supporting that project and sponsoring this video. It appears they really understand the market.

[@leoweary]

I'm glad that Positron is featured here. But you are absolutely correct, it is a hassle to source everything. In my case even harder, when you do it from Germany. LDO are doing a such a great job there.

[@Scharrelese]

Great to see some more Positron stuff, hope the kits come out soon!

[@Peter_S_]

The image from your hike at 1.41 is just over 3 km from where I sit. I'm glad you were able to visit Boulder as the flatness of Denver is not exciting.

[@CNCKitchen]

The Flatirons were a beautiful hike and Boulder is also a really chill city!

[@Peter_S_]

@@CNCKitchen You've inspired me. I think I'm going to go for a hike to the same spot today as long as we don't have thunderstorms. A different view in a live moving camera is available as "Boulder Pearl Street Live" from the channel "Boulder Flatiron Cam". Cheers!

[@sourc3C]

Ive been wanting to see more about the Positron ever since I came across it a few months ago. Very interesting concept, i really hope to continue seeing it evolve.

[@mechanical_bob6591]

I want a positron just because!!!

[@QuangNguyen-wb5kd]

Man I can't wait until a full positron kit available, that thing is so interesting.

[@redone823]

I wonder what they'd price it at.

[@bzqp2]

That PhotoCast idea is genious! It's one of these things that only once someone comes up with it, new possibilities come to mind as obvious as day.

[@HaveaLukeatthis]

Love the look of the cocoa press! Hopefully it makes it way to Europe eventually can't wait to try it!

[@ultima8250]

Hey hey, my top 3 favorite things all in one video, hiking, spaceflight, and 3d printing!

[@granthollingsworth230]

Stefan, thanks so much for putting this together. This was a fantastic video to watch and ensures those of us who couldn’t attend aren’t missing a thing. Awesome job as usual!!!

[@isaacfardig371]

RMRRF was an awesome experience to be a part of. A conversation at the Wuxn booth could've been the icing on the cake. Here's hoping for a 'take two' next time!

[@androidvandroid]

LOOK ITS ME AT 0:06

[@meanman6992]

Glad you got to see some of the countryside here in America.

[@Repkord]

Such a great show! Great overview of some of the highlights and super glad you got to experience the rockies while you were here!

[@frankranager8749]

You drove one of the nicest roads in colorado for sure! The whole 72/boulder highway loop is just amazing.

[@justcraziii]

So glad to hear an update about Positron! Haven't heard much since their very first videos. Glad that such an innovative design is getting industry support!

[@Adam_Carbone]

That Voron printer at 6:47 would definitely be my dream build haha, love the form factor and colors!

[@circleofowls]

Essentium also makes a dual-core 25% carbon fiber filament called HTN-CF25. We use it a lot at work, it's insanely strong and rigid and prints as easily as PLA as long as you keep it dry. It'll be interesting to see if the new Phaetus filament is as good.

[@collective1515]

This is easily my favorite content that you post. I love getting to see where the 3d printing technology is going! Please continue to do these if you can :D

[@richdobbs6595]

It was nice to see you at the festival, even though all I able to do was say how I appreciated you channel. Watching this video was better than actually going to the festival as far as finding out new information.

[@WooHooSum]

ME AND MY FRIEND ARE THE GUYS AT 6 SECONDS!!!!

[@zscept]

the positron is so cool! you can just take it with you and prototype on the go!

[@lazyman1011]

Danke für die super Zusammenfassung und Auswahl und dann auch noch so zeitnah!

[@NochSoEinKaddiFan]

Wouldn't an upside down Voron at high accelerations benefit from having the moving mass lower to the ground? It would potentially shake less and therefore allow for faster printing, right? There are so many awesome ideas out in the world, I absolutely am in love with this community ever since. Thank you for your coverage!

[@oasntet]

I've been using a 3rd-generation Hero Me on my ender 3 for quite some time. The part cooling is absurdly better than the stock ender 3 cooler. If I care about surface finish, I can print up to ~60° overhangs. If I don't care or am willing to do some sanding, it can go all the way to 75°. Bridges work great, too.

[@Fifsson_]

Also the ability to add/change something on the toolhead by just printing another piece of a standardised set is amazing.

[@WowCoolHorse]

@@Fifsson_ wow that sounds awesome

[@PB3D2]

waou excellent, war gut..wiel spass , danke fur alles

[@idiotluggage]

Really cool! I just started printing this year. If I had know about this festival I would have gone. I am going to have to look up RepRap now. Thanks for sharing.

[@Lukylbc]

PRUSA JUST UPLOADED THE INPUTSHAPING FIRMWARE!!!!!!!!

[@davidrandall4001]

That was cool, had no idea some of this stuff was out there, so many thanks for covering this convention. It's provided alot of food for thought on future projects.

[@GoingtoHecq]

The Polar printer definitely interests me the most. That they did it in Klipper is very encouraging for me.

[@azdronedude]

Great complete review at RepRap Festival Thanks for sharing

[@joshcarter-com]

Stefan I enjoyed meeting you at RMRRF! It was an amazing chance to see so many 3D printing enthusiasts under one roof. I ordered a Voron R2 kit the moment I got home and my wife nearly ordered the chocolate printer. 😊 Thanks for your coverage of the show-you found some cool projects that I missed!

[@michaelwiginton8587]

Love the coverage. It highlights some very interesting ideas.

[@al1sa920]

Kralyn is an absolute genius. Glad he found sponsors for Positron

[@Sembazuru]

Yeah. And LDO is positioning itself nicely in the niche of kit printer middleman for open-source printers.

[@Fifsson_]

​@@Sembazuru I would also add the Orbiter to that mix - I feel like they are trying to say "we can make your design into a product", which is a win both for them (profit, and they also don't have to invent on their own) and for the designer (who gets to have their design manufactured without much of the hassle that would come with doing that alone on a small scale). It's quite smart to be honest.

[@EIEIOOOOO241]

Love the travel montage! Something different, unique and cool!

[@alonraz6477]

Please review more of the positron project! Can't wait for the kit to come out

[@Sembazuru]

With careful orientation of one of the two coloe co-extrusion filaments on the polar printer, you could get a vase mode print that is one color on the outside and another color on the inside.

[@explodingonc2782]

Chocolate printer? Now that's true CNC kitchen!

[@jowjor]

That belted voron. That's genius. I need one.

[@thecatofnineswords]

Machinarium chocolate robots!!! ❤❤❤

[@vonmoraes]

you gonna make videos about positron soon? i like find this project very interesting. Another project that i found on youtube some time ago and i didin't see more content about i'ts mulbot, have seen this in one video of you, and found very interesting.

[@JanTec3D]

Great video as always, I really liked the Positron and Phaetus Filaments!

[@rcmaniac25]

It was great seeing you there and glad you could come out. It's funny, the table I was at was in many of your shots but somehow you got it every time myself and booth mates weren't there. Though I did see my back once :P

[@marcfruchtman9473]

Awesome! Thank you for the video!

[@Lucas_sGarage]

8:33 if im not wrong, marlin supports rotary axis by default as well

[@TomasoPiantini]

Thank you for this report

[@chrisufo05]

I live in Loveland and didn't know this festival was going on! Totally will need to go next year!

[@makingtolearn]

It was very nice to meet you there! One of the things I found most interesting there was the work being done by Utility Research Lab. I also noticed quite a few printers with belt driven Z axis. So many Voron printers! The Voron printer in the Fabreeko booth with the EDM cut linear bearing rails was insane.

[@TheNextDecade]

This was wonderful! Thanks for covering the event, I had no idea about some of these projects! I hope you can come visit ERRF later this year, Last year had some really neat stuff!

[@XA--pb9ni]

Ah yes the obligatory german hike in the mountains. That´s what i like to hear from a fellow german!

[@religionofspeed]

Man I kinda though this was going to be a little event and skipped to go racing instead but it looks like I should have made time, especially if I knew you were coming all this way. Glad you got to see the Rockies and hike a little too while you were here, even if it wasn't the best season for it.

[@LincolnWorld]

Thanks for the video! More stuff like this please. I loved it. Hopefully you won't have to fly as far for the next convention.

[@lanceanthony198]

The positron is simply the most promising 3D printer design since the original desktop printer

[@ColoradoAdventureClub]

I saw you there thought that looks like the guy from CNC kitchen.... IT WAS!!! I wish I could have just said thanks for all your content!!! Some of this stuff I must have missed or maybe it was there on Sunday? There were a few really good ideas there!!

[@beauslim]

That's funny, the HeroMe popped up in my search results just before watching this vid. I think you must be giving it a bump.

[@chipcode5538]

Maybe a bit off topic here. I had this crazy idea to increase print strength. The weakest part of a print is the layer adhesion. What if we design a solid part. Print the first layers as normal. The perimeters are printed as normal. Now for the fill we skips about half of the layer lines in a tooth like pattern. The next layer is printed at double layer height filling the open space and sticking one layer height above the previous one. The principle is repeated for the full print. Hypotheses: The layers stick to both the bottom layer and half of the sides of the previous layer and as a result the print will be stronger. Can you test this or is this already tested?

[@RedSlashAce]

Oooh! I missed that construction filament!!! Definitely interested in seeing a review!

[@jameslmorehead]

The Photoncast has my interest. At work, we use a large amount of one off insulators for high voltage and high current buss bars. Being able to coat them like this with a, insulating resin would greatly decrease our production time on prototypes. Also, the Co Extrusion filament has always caught my attention. The ability to add such a strong material to a print would take most prints from testing ideas and low strength cover plates to more structural parts, again for low volume prototype equipment. The only problem so far is that every retraction requires a filament cut to sheer the core material.

[@johnmulligan9299]

Found you channel today. I enjoy 3D printing as well.

[@Sazoji]

did you see the creepy denver airport horse? we had a van break down in a town nearby and had to uber there to get a rental and get to a hotel lots of interesting stuff in the area, we were planning on driving through, but the long weekend of waiting for repairs was a lot of fun.

[@CDSMadeIt]

I'm definitely super glad to see that the advancements haven't stopped behind the 3d printing scenes! The year of the Bambu lab was a little discouraging for me. But the voron builds are super inspiring! Definitely what I want to do next!

[@Nolano386]

Polar printers are so cool. I think there's a lot of potential there

[@icemanbldr]

please show more! I'm disappointed to not have known about this show as I'm 60 miles away and would like to have attended. Looking forward to more videos about the meetup. I thought of NASA technology being used to transfer power and signals via rotating interfaces to antennae etc. on satellites when I saw the polar rotating printer.

[@JustinBuildsThings]

i want to see more coverage on the roto casting project it was there last year and probably the most interesting project

[@AndTecks]

I made that part cooling hotend :D. I love it

[@biggestbigmac9525]

Moin, kannst du bitte mal das gst3d filament testen? Das ist richtig günstig, die Meinungen darüber spalten sich aber sehr. Mit deinen Premium Tests könnte man da eine klare Linie ziehen wofür es gut ist und wo seine Schwächen sind. Mach weiter so! Deine Videos sind perfekt👍

[@steverileyretired]

Very Good Video

[@tulio3dprint]

4:54 turning a 3d printer, type ender 2 has the same result, since if it sticks well on the bed the result is the same and cheaper than this printer

[@Demertech]

Your ford was just being a ford. It's in its personality. It just wanted to take a break 💔

[@HotboiEngineering]

FOUND ON ROAD DEAD NEVER BUY A FORD HOSS

[@forbiddenera]

​@@HotboiEngineeringbeat me to it 😂

[@alexanderzawydiwski9534]

You’re lucky the doors in the wheels didn’t fall off

[@camdavbax]

FORD is all good as you start... It's coming back that's the issue. Driver Returns On Foot 😂

[@Random9rA9]

I have a suggestion for a new Video. Does recycled filament has the same advantage than annealed PLA? Can you test filament from Recycling Fabrik and compare it to regular PLA?

[@RixtronixLAB]

Nice info, thanks for sharing it :)

[@theodoreburns1330]

The at home rotomolding machine is such a cool idea! It would be cool to see it automated at some point.

[@AnIdiotwithaSubaru]

Loveland lol. Would love to hav gone but ill hopefully be going to MRRF

[@meanman6992]

That 24x24” printer got my attention!

[@JohnLattanzio98]

The pritner with the rotating bed is printing the taco bell bag!

[@paladingeorge6098]

The photon cast looks like an amazing machine for small businesses. How many cycles do you think a single printed mold can withstand before deformation?

[@SuperEdiggity]

Drove up from New Mexico, super fun show, lots of mind blowing stuff, but the tpu voron actually broke my head, I didn’t know imput shaping has come that far

[@MrBaskins2010]

love that the cocoa printer uses a 0.8mm nozzle standard :)

[@jokero1717]

I have a like because I saw myself in your video!! I thought I recognized you, but I didn't want to be weird. I love your content!

[@Justin-ng4zg]

LOL! good job FORD!

[@neilfpv]

The best job! :)

[@chadbeardall3660]

I DIED when he said that his Found On the Road Dead (FORD) broke down!

[@skyrider4789]

Thank you Stephan, for another great video. 👏 The things I found most interesting from this one: The Cocoa Press and the Photon Cast. Very cool to make the effort to showcase the individual companies and their projects. I've seen similar videos that leave such details out. * Unrelated, do you ride motorcycles & know who Valentino Rossi is? 🏍 You could pass for his doppelgänger or long lost brother. He's pretty chill and funny too. 😊

[@Lucas_sGarage]

I was wondering, can you investigate if coating each layer with CA glue improves the layer adhesion?

[@Vandy_fpv]

Love you

[@DaveDarin]

Regarding the chocolate printer. Now this is cool. I see that they recommend their chocolate to be used and that it is formed to meet the shape needed for the printer. What will be unique here is that the chocolate would be much easier to recycle vs. filament. However, it would have to be melted down and put into a mold that shapes the chocolate correctly so it fits into the unit. Now I am not a baker so I do not know how many times chocolate can be remelted. So, initially printing something that fails, then to melt it down and reshape the chocolate into the needed shape for the printer and then, again, printing a new shape using the printer might be an issue as I am not sure how much melting and remelting of chocolate can be done.

[@dempa3]

Thanks for this interesting video on new an upcoming 3D printing tech. If I may suggest subjects for future videos, I'd like to see a review of Prusa PC with carbon fiber, and how it compares to PC Blend, and Polymax PC. Additionally I'd be very curious to see how the print settings, which produced the transparent and tough parts, compare to annealing in salt.

[@JSunBurns]

You were so close to my home! Iowa

[@frank-af]

"I get the feeling they did it mainly for the challenge" You definitely wouldn't be wrong there 😅

[@lukazz434]

6:46 do i see there a voron micron kit? :D

[@LeonMatthews]

Great overview of the event, thanks! Honestly, I would have liked to see even more detail. It seems like a long way to go for only a 15 minute video... Maybe you could release in-depth videos for each of these 10 projects, with interviews, your thoughts, etc

[@CDRaff]

I'm so sad I didn't get to go, my wife had an appendicitis the week before so my plans got binned. Looks like it was a lot of fun though.

[@Leviathan3DPrinting]

The paper bag 3D print has me weak lol

[@nerys71]

Love seeing my rockets in your video! you came really really close to being eaten btw. 3d printed shoes AND they were orange. if I thought you were a size 13 I just might have bitten you and made off with them :-) muahahahaha

[@McStebb]

I thought I saw a guy that looked like you in Zack Freedman's latest video... it really was you!

[@redheadsg1]

HeroMe cooling is ok, i was using it for a while but i noticed that it is using a lot of hardware [screws, nuts, inserts) and it was really annoying and complicated to mount or dismount on my CR10 and Ender X adapter plate. So i used his mounting solution and change it to a better one that Petsfang was using and my design use only 2 screws to demount whole setup (not counting hotend).

[@TheJustinist]

1:43 - A random Nero appears

[@naso4265]

As soon as i saw the price of the 3dchameleon, i instantly bought it

[@brohdebennett2738]

Hi Stefan, Could you do a video comparing the strength of Bambu Lab's different filaments? I'm a manufacturing engineer, and I was able to talk my boss into getting an X1-Carbon. I need a filament that is strong, impact resistant, and has good wear resistance. I am especially curious how the PC, PLA Tough, PLA-CF, and PETG-CF stack up against each other. Thank you! Brohde
