Tarântula articulada

Hello, i bought the model yesterday and every time I'm trying to upload it to Mainsail it doesn't work. Every other file works. If I put it onto the SD Card manually I can start the print, but it will stop mid print. I first thought it might be my klipper configuration or my slicer but as I said, every other file/model works. Any Idea what that could be?

I used the V3 model and wow does that print good on my X1C. Only takes about an hour to print and they pop right off the bed with a little force. The model is much stronger than I expected. As always, you are a master of your craft Mcgybeer!

Just paid for and downloaded the files but the stl was not in the folder

Hi there, I've just purchased this STL and loading it into Bambu Studio, I get the error message "Error: 364 non-manifold edges" .
May I ask if I should ignore that an print or should this be fixed first somehow?

The error occurs on these files:
* Tarantula_v2.stl
* Tarantula_v2_baseA.stl
* Tarantula_v2_baseB.stl

Error DOESN'T occur for Tarantula_v2_baseC.stl

MK3S+ here trying to print with Tarantula_v2_baseC.stl and have also followed all of the tips here: https://www.mcgybeer.xyz/printing-tips and just cannot finish the legs. Tried several times now unfortunately at 150% w/ PLA. Even using a 75C bed temp to try and keep things down. Really no other issues with many other prints to speak of, just something about this STL.

I think the curling was eventually fixed with your tips but the last attempt still popped a couple legs off the sheet about halfway up. Currently trying 1 last time (I enjoy pain) with a massive 10mm brim.

Tried this on a Resin Printer (Mars 2 Pro) with 80% scaling (about the size of my living tarantula)

and it worked on the first try! (guess i got my settings pretty good)
I used the C Model it did take a while to get all the extra material off with a clipper and a sharp knife but it turned out great!
using ptfe spray on the joints also helped a lot to make it move more smoothly.
Thanks to mcgybeer for providing us with such a high quality model!

I love this model. I have resin and fdm printed it. Would it be okay for me to sell a few printed models?

I picked this thing up.. and unfortunately I cannot for the life of me get a successful print, the legs keep popping off the plate once they are about halfway done, any suggestions?

Fellas.
I wish I had a way to show you my prints of this amazing creator.
The model is very much PRINTABLE.
Since I am a complete noob, I do not know how to regulate my infill on different parts of the file.
So... I just reduced the infill to 5% and used "3d infill" instead of hectogon.
200% scale comes out the best. 150% scare more ladies around the office, but the light infill makes the print fragile.

Best of luck. I wish I could attach my pics.

I can print anything without issue but not this spider. I give up.

Is there a way to print the legs separately? A-la-Octopus The Great?

How do you make these?? Is it a 3D modeling program that anyone can buy? They are so good we’ll done!

Thank you very much for your quick response. Sincerely.

Bonjour, je suis un novice en impression 3D. j'ai une elegoo mars 2 pro. Je n'ai changé aucun paramètre et j'ai lancé l'impression. 4h30 de print pour un résultat un peu décevant. Pas d'articulation, les pattes étant fondues au corps. Je ne critique pas l'auteur de la figurine. Simplement cet d'objet est il fait pour les imprimantes SLA ? Que dois je changer dans les paramètres pour avoir des pattes articulées ? Cordialement.

So I am pretty new to this hobby but I printed one successful on the first try just from using the creators suggestions, came out amazing. Here's what I ended up tweaking.

Tarantula_v2_baseA.stl
0.2 - Layer Height
Main Body 15% Infill
Legs and Palps 0% Infill
50 mm/s Speed
8 mm/s Initial Layer Speed
0.6 mm/s Z hop Speed
100% Fan Speed
200% Scale

I had to look up how to change infill being so new but its super easy once you look it up. Good luck to everyone else and thanks to Mcgybeer for making an amazing model.

in the background of the video you have provided for this print, there is an awesome dragon, do you have the file for this print and maybe a video on how to assemble it?

I'm also struggling to get a good print out of this model with the A version. It's pretty much as described in comments below. Something always goes wrong on the early build up of feet and a couple of inners always seem to fail. Tried 5 times now with two filaments and lowering temp on PLA that doesn't normally need it. I've no problem with other prints and adhesion directly before and after this print so I'm going to try the full raft version next in the hope that helps without being too much of a clean up pain.
Any other pointers gratefully received

Nice, thanks for your feedback.
No special tricks for the surface finish. Just the filament used, and sometimes some paint touch (like the blue on the giant tarantula).

Also, @mcgybeer: i didnt mind too much it failed. I have my printer about a week. Although i'm pretty convinced the calibration is well done (benchy etc) i still need to learn a lot. And you do that by failing :) So it allowed me to learn on supports etc in this case.

I do have a question to you as an experienced maker: how do you get the matte surface finish? What kind of filament and techniques do you use?

I've successfully printed the A model at 70% , but with custom enforced supports in prusa slicer. However the supports were a bit tight to the model (stuck) so i will tweak a bit with it, at 70% it proved easy to break the lower part of the legs.

Will today test at 120% (roughly 10cm front to back) with supports

That's warping/curling. Increasing the Z-hop helps a lot to deal with that. Also lowering the nozzle temperature, if the filament allows it.
I saw a bit of that on my Prusa Mini, but not enough to be an issue.
Also ambient temperature makes a difference, no kidding: it works better in winter hahaha

Unfortunately it failed again. But now i know exactly what is the problem. During the feet build up the perimeter layers in the feet and are lifted up during the printing creating a buildup of PLA above the currently printing height, during the printing process the nozzle crashes into the feet and displaces them in the bed. After that the print is doomed. I really don't know how to compensate for that. Maybe printing it on bigger scale. I am using 3 perimeters for the feet with 0% infill, and 15% for the rest of the model with triangular pattern. Prusament PLA galaxy black, 215C nozzle and 60C bed.

Just uploaded a new version ("Tarantula_v2_baseC.stl") with a quick fix. Printing it myself right now. Hope this works and solves your issue.

Happy to test print as soon as you post it, i have my printer idle right now ! Thank you for you commitment.

Second failure reported on a Prusa MK3, so maybe I'm missing something because that can't be a coincidence. I've printed several on my Prusa Mini, and yesterday I printed one at 150% on the Ender 3 v2.
I'll upload an improved version with larger tabs ASAP (maybe a huge tab holding all the legs together).
Sorry for the inconvenience.

Hi there. MKS3+ owner here. Tried it two times on my printer with the A version of the STL.
While the outer part of the legs are still firmly in place, the inner part of the legs all came loose - except for one.
I am printing with PLA. First layer looks perfectly smooth, no adhesion issues. Steel bed was cleaned properly with isopropyl acohol.

Bit of a bummer to be honest :D

(i tried once on 100%, once 120%, stopped the print after roughly 60% of the print, where the lower part of the inner leg part was printed and about 3 mm of the second part.

Mmm... That's weird. I've printed several with no issues on my Ender 5 and my Prusa Mini, and your MK3 should be a far better printer than mine. Anyway, if someday you want to give it another try I'll be glad to help ;)

The printer is a prusa mk3 with great bed adhesion and 0 problems so far. I washed the bed with soap and hot water and cleaned it with IPA before starting the third print. The easiest would be to use a big brim. Although i will not try again, maybe someone else tries with a brim. I really appreciate you prebuilt supports but maybe they need to be a bit bigger. Thanks anyway for your support.

@GPPETTO
I know it is quite a torture test, but feasible for a well calibrated printer. My two main recommendations are to improve bed adhesion and deal with warping/curling.

For the first one, just be sure your bed is well calibrated and clean (I use IPA). Proper bed temperature (if heated), and maybe some stick or spray depending on the material. I used hairspray on my old printer with glass bed and worked like magic. Lowering first layer speed, even down to 8-10m/s, really improves adhesion. And also increasing thickness for the first layer, around 0.3 mm, helps a lot.

To deal with the warping/curling you should enable the z-hop (~0.4 - 0.6 mm), because the extruder may collide with curled parts and loosen them. To reduce the curling it's important to have a good layer cooling. Check it and be sure it's set at 100% speed and you have proper airflow. I improved my prints a lot just changing the stock fan duct.

Hope this helps!

Unprintable model. I tried to print it 3 times and the last time was in 140% scale and i was unsuccessful. The feet are always get lifted from the bed and the print crashes. Unfortunately i am giving up on this model.
