Imagine all the custom rims you could make for large technic builds 🤔

I really liked the idea of printing train tracks. I dont even have a Lego train or a 3d printer but this sounds like such a fun piece to print of your own design. You can adjust the peice design how you want it for your Lego city so it fits in any place.

Very exciting series. Thank you! I already use replacement cloth for sails and watchmaker back seal for rubber rings in a Lego build. 3D printing makes even more possible!

Thank you for being willing to try again! Much better results this time.

I'm looking forward to see more episodes! Adjustable springs made by 3D printing is my next goal

So there are settings called expansion settings, they change how much the filament is expected to expand when deposited, so if you adjusted the value to compensate a little less then you would make the holes and pins the right size, your issues are entirely your settings and a lack of experience with the machines, in the first video the issue was that the printer will do a bed level check and make a map of that, you have to adjust the z-offset, or the distance the nozzle is from the bed when printing to achieve a perfect first layer, you were just too high on the previous video and still a little too high in the second but much better, that's all. Most of us take days to get a new machine calibrated perfectly so it's not a shock you had some trouble. Nothing wrong with it or you. Those files work great. On top of the expansion settings you can tune your supports so they leave gaps between it and the part sides so that they can be removed much easier and don't fuse to the prints. Just settings. You can print lego with no problem of FDM/FFF printers, but resin does the best, aside from injection.

I love this series!

About the supports inside the pin hole - I'm designing those parts myself in solidworks (I would be lazy if I knew there was such cool tool though), but if you make surface of those sides of the pin hole slanted, you don't need support. And it can be something like just 15 degrees depending on how thick layer you're printing.

Great idea to cover this subject, LEGO and 3D printing. Love it. My favourite 3D-printed LEGO additions: RIMs and boat hulls. In case you need any inspiration ;)

try to print some custom spoked rims for some of the cars on the wall behind you

This is a really cool series, thank you

You should print technic rims !

High quality content as usual!

I bought some 3D printed monorail track from 4DBrix years ago and I'm still using it now.

What a grest idea to just 3d print Lego bricks and sets! I'm surprised I have never seen it before!

Great video. I personally tried to print lego components. The best solution for me could be to use an SLA printer as the quality is better and the joint with the original legos is more solid. I printed an entire lego technic set in 2:1 scale using PLA and ABS, in this case the result was satisfiyng.👍

Y’know i would like to see excavador tracks 3D printed

My needs would be far too infrequent to bother owning a 3D printer but always interesting to see other people experiment with them. I do however use Trixbrix 3D printed narrow gauge straight track, large radius curves and points, which have been free of issues.

I’d love to see DIY-printed 9V track: creating the plastic base and then adding strips of metal to it. 9V track is like gold!

Use "horizontal expansion" in your slicer to make more plastic without increasing the overall scale.

Can you make flexible beam to add suspensions to your model ?

I've been waiting for this one. I should buy some trains :D

Nice Video!

One cool thing you could easily do in the printer is really high detailed props for the "utility" technic sets. Like in the excavator or trucks you could print some ruble pieces to put on the loader and bed of the truck. really cool vid

I definitely got to get that train track cross

I'd really like to see how your 3D printer would handle Lego pieces that have bars or clips in the design. Some of these pieces can be very problematic in terms of brittleness with their age, but printing something like part 30377 in teal/dark turquoise could be very helpful for someone with any Life on Mars sets for example.

with the rails and most other files that don't have any "vertical features" (like the holes in the custom technic frame) you can just push the layer height to .3mm to go way faster.

i think the Speed Champion 2023 sets are released on certain websites as a sort of replica or early access, you should definetly check those out!

you can use meckabricks to export a (kinda low poly) 3d model of allmost every lego piece.

The fact u can create custom parts that dont exist and use them for technice builds is the best fact id say tho.

Very interesting again. But what do you do with prints that were not good? Can you recycle them somehow?

i have an 3d printer (ender 3 pro) myself and 3d printed some custom lego technic pieces never had any issues and in my experience i never had to use any supports i now have upgraded too an bambu lab p1p i have found that the tolerances on that machine are way better and i didnt need to change the dimensions ever on that machine but i never printed lego pieces on that one

There are a few pieces I would like to see. Like a slope corner combining 33 and 45 degree slopes. But I am not likely to get a 3D printer myself until I can find one that lets me print Poser figures in N scale.

Are you going to make shock absorbers for the Batmobile? (!)

Also, you can print lego roller coaster peices

RacingBrick doing a 3D print series just after I bought a 3D printer. I can see myself doing a lot of experimenting.

can u show us all the alternate builds from the buggati bolide

He's gonna print tires with the tpu, because it is flexible.

Aren't some of these connections at risk of being illegal? As in, connections that are "too tight" may slowly damage the Lego piece. I think it's the reason all dimensions erred on the side of looseness in the blueprints.

Resin printer next tho

Cool ! P.S. I thought there will be some info about 42146 :)

Hey man, I got a flash forge adventurer 3d printer and after a couple uses I just didn’t like that I couldn’t get much detail from it, I purchased an elegoo resin 3d printer for roughly the same price and started making custom parts and I didn’t need any clean up I just cure the print and it fit with existing Lego bricks

Maybe leaf springs?

I tried printing some of the tracks, all worked well except the track switches, Lego has a spring in the switches and the 3d printed parts don't which impact the trains when they hit the switch from the opposite direction :(

Rare star wars minifigs? Or better rims

Resurrect the Lego Technic figurine, hehe.

3:10 ah yes 3ds max 6, now that's an interface I haven't seen in a while.

These videos are great but I'm so conflicted. On one hand I love the challenge of only using pieces LEGO makes for models, but I also love making CAD models and 3D printing. Also great to see another 3DS Max user! What did you use the software for?

All the issues you're having in this video are solved by "horizontal expansion" option in the slicer. By tweaking it a little you can adjust studs and holes size and you probably only need to do it once for your printer.

Jó napot Balázs. van nekem egy kis kérdésem, ha bírná megmondani. A legó 9 voltos sineket lehet rákapcsolni a modern legó műanyag sinekkel?

Try to print comp 61903. Or was it asked already?

I want you to 3d print custom lego connecting rods for MOC locomotives.

And print drift tires with the soft material

hello bro please tell in 4dbricks what the difference is between standard model and surfaced optimised model , please tell.

I want to see more with people printing lego compatable parts with resin printers. Much higher accuracy and faster printing should make veryical holes and horizontal holes.much more similar in tolerance / fit and would make batch printing / printing larger parts much faster.

Try to make a little technic car with the prices!

i always wonder if the lamp is aligned with the crane intentionally or not

Can you try to make a Lego constration piece

what 3d printer did you use because im looking to get one

What about resin printers? Can you get better results with it?

Hi👋

I really like 3D printers, but printing LEGO related bricks/components feels like cheating on your girlfriend haha

Hey

what about resin printer they far higher tolerance than FDM

Hrm first thought is suspension then pullback motors and clutch and now it's motorization a

Let me know how to make your 42077. Yours is very cool and i want to make it

maybe try a resin printer?

"Printed ABS less flexible than PLA"? It's exactly the opposite I think. PLA is very brittle, while ABS flexes quite well in comparison.

I would be most interested in if 3D printing works for minifigure accessories? For instance, due to Lego's anti-war policy they intentionally limit weapon options, but there's a lot of gun types that would be nice to have for the Star Wars line.

Pinholes and Studs are the WORST for FDM 3D printing of Lego Components. I had a model I built that worked perfectly and created great results for me off my printer. I shared the files with another club member after they gushed about my 3D printed model at a meeting. Come to find out he couldn't get it to work, and he blamed my model instead of his printing environment. If he'd not just gotten mad at me and complained behind my back, I would have helped him with the issues... :P I hear resin printers have better tolerances than FDM.

what slicer is he using?

are you related to @StezStixFix ? you look like brothers

who is stopping someone to make 8 stud or 10 stud wide rails

First
