Easy shell tool

Recommended Posts

Posted · Easy shell tool

Hi everyone!

I got some 3D model I would like to print but sadly it doesn't have a thickness. I do have to add it manually for each piece.

I'm quite inexperienced in modelling but I tried with 3DS max the shell modifier tool to add the proper thickness...it works for simple geometry but I've got lots of overlapping polygons, inner shell extruding through outer shell and many other issues for more complex geometry.

Does anyone know a simple tool, or maybe a step by step tutorial to create a good thickness for 3D model in order to get them ready to print?

I've a Mark7 Iron Man Armor to print size 1:1 :D

Thanks you for any tips/tutorials/tools/videos you can provide

    Hi devilflash,

    I've had to do the same for the Mark3 Iron Man suit for a friend and we did use the shell of 3ds Max.

    Over time we managed to simplify the process a bit but overall here is what we did:

    For every part we wanted we took the surface only (our model was nice outside but not valid for a wearable suit inside):

    - We made our objects Editable Poly

    - Use the selection tool with Ignore Backfacing on and By Angle (depending on the case but usually something around 20 worked well) to easily select the faces of the surface.

    - Detach every surface we wanted to be considered as separate objects.

    - If the object was very high in polygon we sent it in MeshLab to reduce the number of faces using Quadric Edge Collapse Decimation. Export as obj and bring it back in 3dsMax.

    - In some cases we created a lid around the surface of about 3mm.

    - Use the shell modifier. We used about 1.5mm (inward only) and used the Straighten Corners option. You will probably notice spikes here and there. These are the places you need to go fix.

    Hope this helps

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.

        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
