This is Magnificent！

@Invert_Ignis

Please put it in first place!

It probably took hours to make it. It deserves a blue ribbon!

hello, are these sections available?

The designer has replied

@brajer.jan

Hello, I am still optimizing them, therefore they are not. I want to release them as soon as possible and they will be added to this model with an updated guide.

I'd love to start the journey to build this epic model. Do you know when these parts might be added?

pictures do this model no justice. It is dense with detail. I will look to ensure the model can be opened and explored in a similar way to the original with rods and a side stand for the core to open out on. It is a magnificent achievement by the author. I really hope he finds the time to model the rest of the Atlas experiment. A model such as this probably has a limited audience but every physics school should have this on display, and allow pupils to strip it down and reassemble. Again, just a magnificent piece.

Just a note, the very centre is absent as I am waiting for some glow in dark filament. while I can't collide particles I can at least fire off a few photons.

@brajer.jan

Hello, I am happy you like it. I am working on the rest of the model, but this period at ATLAS is just way too demanding for me to finish it. I am trying to make it as user friendly as possible, making it even bigger task. Sorry you have to wait. Best regards, Jan.

I am very grateful for all your efforts and I will continue to do additions whenever they are available. The model will be on display at my son's A level physics department. It will have a name plate, with model details. I would like to add a credit to yourself. Would it be ok and correct to say "Modelled by Jan Brajer" ?

Good model. although Instructions for the outer copper muon detectors were a little bit unclear, I figured it out in the end. I needed to drill out quite a few of the magnet holes, but i used a 0.6mm nozzle with 0.25mm layer height, which may have caused the imperfect holes. Currently waiting for the designer to release the files of the two circular muon chambers on either end of the collider!

Just an update on the model; The image uploaded by the poster is taken from https://atlas.cern/tags/detector, and is not the same model. They are very similar, but the details are a little bit different. Another thing, is that the text has been covered up for whatever reason in the published photo. Not exactly sure why

@Supernovaxo

I definitely need an assembly guide before I even dare to start printing this. This is crazy..a must win for the contest, even worth top consideration with a detailed assembly guide

The designer has replied

@brajer.jan

Hello, the assembly guide is in making, I plan to upload it tomorrow.

I had a bunch of old filament to burn so I decided to take a crack at this. I ran out of light blue and copper/bronze right at the end so the outer ring of detectors on mine are also different. I made this with zero magnets. I really just wanted something cool for my bookshelf, I didn’t see myself wanting to take it apart and reassemble it. If you try make it without using magnets its a measure twice cut once situation. Pay attention to what you’re doing and you’ll be fine. 1/2

2/2 A few suggestions for the designer/others after completing the model: -Photos of the completed model/renders from different angles would be very helpful in the PDF. -I suspect that all the torroid skeletonized parts that don’t have through-holes can be printed with no supports and save a lot of time assembling. The whole thing took me about 8 hours to assemble over a rainy weekend, which is still quite impressive. -I folded little accordions of cardboard to hold the muon detectors in place while gluing them instead of using magnets. I suspect this could save someone a lot of time. -I merged all the “feet” of the core assembly into one plate and printed them all together. -I added a 1:100 scale figure standing where he would be dead just to give it a better sense of scale. -Assembly of the torroid is critical. Really pay attention to make sure all of the joints are fully engaged. I had one singular joint pop out and didn’t notice it until the glue was dry. It was a very delicate job to fix. -Keep a chisel, a box cutter and a flat tipped screwdriver handy at all times to remove the support interface material. -The guy who gave the crappy review saying the print wouldn’t stick is crazy. The model is oversupported not undersupported, his complaints are cause by user error. I did bot have a single failed print running the whole thing.

i would like to print this, but this requires 644 magnets? is that correct?

The designer has replied

@brajer.jan

Yes, it is correct, the magnets could be replaced by studs (322 3.8x4), but I highly advice using the magnets.

@Magmabow

Replying to @brajer.jan :

sorry, i phrased the comment badly; is 644 the quality of magnets or a magnet size?

@brajer.jan

Replying to @Magmabow :

644 pieces of d=4mm h=2mm magnets

@MoitieRosbif

Can confirm, this looks and works just like the real CERN experiment. minus all the particle detecting

@fantality_ceo

so we accelerating particles..?

@etienne.savalle

Hi @brajer.jan, First, thanks a lot for this model, it has a a lot of details and I have some colleagues that will be really pleased with this. I have a small feedback for users planning to print with PETG : the Barrel 3 Muon 4 plate when printed in PETG yields weak parts that then to break once removed from the bed. For this plate only, it might be useful to increase the number of perimeter by one or two. Can't wait for the next parts of the experiment !

(Edited)

The designer has replied

@brajer.jan

Awesome! I am now also printing it (slightly updated iteration, where I am trying to optimize the amount of magnets and some other little tweaks). Sorry to hear that, I printed the whole thing in PLA and had no issues so far. could you please add a picture of what went wrong ? I will try to fix the issue and update the model/profile.

@etienne.savalle

Replying to @brajer.jan :

I do not think that there is something wrong with your model, it might be the PETG that make it weak. In the attached picture, I circled in black where it broke. I would simply increase the number of perimeter when printing in PETG. It might be the case for Barrel Muon 4, Barrel Bot 3 and Barrel Bot 1. Could you also change the 3mf file in BambuStudio for The Calorimeter Barrel ? Without the AMS, the calorimeter barrel has its feet too close to each other. This is not the case in the AMS version.
