I'm an old school 3DS Max guy but haven't touched it in like 8 years or so. Lately I've been very inspired by 3d printers and have been thinking of getting one in the spring when the money picks back up. But as cool as they are I don't want to just print Benchy's and other thingiverse fodder. I want to design and print my own stuff.
Long story short my old version of 3ds max doesn't want to work on my computer for some reason. So, I downloaded Blender. There's a bit of a learning curve but I'm slowly figuring it out. Any Blender gurus out there? I may have questions. Thought I'd share my first design so far and get input. I know materials in Blender are pointless for 3d printing but I threw some rough colors on stuff to help me visualize during the design process. Haven't started on the hood or floor pan yet, but trying to keep the design broken into manageable pieces since it's likely my first printer will be a smaller build platform. (Looking at the Ender 2 right now.) Still have some cleanup to do on the mesh, corners of the bumper, edges of the fender etc. and more details to add.

I'm a 3DS Max guy...not an expert, exactly, but it's what I use. I have a bit of experience with Maya, know just enough about modo to never want to touch it again, but have never used Blender. So far it looks like you're off to a promising start. What sort of workflow do you use to make a tire like that? Or the rest of the chassis, for that matter?

Thanks man,
I use a combination of box modeling and spline modeling. Anything designed for 3d printing has to have volume though so any spline modeling has to have a Solidify modifier applied to it when you finish the part to add thickness or it won’t translate to gcode in the slicer software. The cool thing about Blender is, it’s open source and there are tons of add-ons and they can be downloaded and added to the program right from the user preferences menu without restarting the program. During my research I found out about the 3d Printing Toolbox add-on which helps a lot in analyzing the model. Meshes have to have volume, and be manifold (water tight) or the slicing software won’t read them right. I actually modeled the tire by extruding faces and tweaking vertices on a torus. Originally I tried spline modeling a tire like I would have done in max by wrapping an array around a central axis point, but every time I would click the “Make Manifold” button on 3d Print Toolbox the mesh would go all to hell. So went back to the drawing board tried starting with the torus and it went much better. I still don’t have a 3d printer so I’m sure I will have to make adjustments and redesign a few things once I actually get to try printing the parts. Some things that look fine on the screen will run into issues in the real world. Being a musician in Nashville for a living the income drops off dramatically in the winter time, but figured that gives me some time to have some designs ready to try as soon as I get a printer. Also I have to keep in mind I can’t make any lines too thin or the printer will ignore them. That’s why some of the details look kinda thick. Of course you know all these things, but it's stuff I've learned along the way. Which printer do you have? I'm thinking about getting a CR-10. Quote:

Well, I know enough to know that I still have a lot I can stand to learn, so I like to ask others about their experiences when I can. As for my printer, I have a Zortrax M200. It's pretty fantastic, though it is comparatively expensive.

I'm no expert myself. Someone like Nogamusprime would see how I'm modeling this and probably laugh or have a stroke...
Slow and steady progress though. I've got the bulk of the body shell done now. Still have to clean up some vertices on the rear after just straight copying the mesh from the front end, to make the rear. But I wanted to make sure my fender openings matched. Remaining checklist: Clean up rear vertices Model tailgate and rear bumper Model floorpans Model roll cage Model Interior (seats, dash, etc.) Design connection points to connect it all together After that I plan on making multiple variants of the jeep by manipulating the original model. Planned iterations include 1. 2 seater roll-cage basic jeep (the one I'm building now) 2. Hard top enclosed version (various rear turret mounted weapons) 3. stretch both for rear seat variation 4. stretch further for 4 door version 5. truck cab (2 door, extended cab, 4 door) and bed version 6. bed variations (ambulance body, tow truck, utility bed, personnel carrier etc.) 7. Tank tracks for a half track kit. 8. Lift kit and oversized tires. Once (if ever) all that is done I've sketched out some other vehicle ideas. Big truck, tank, semi. Each one with multiple iterations planned. I've looked at the Zortrax machines they look awesome, but way out of my price range. Looking at the CR-10 because it's around $400 and has a large build volume. May cheap out initially and get the Ender 2 to get me started because it's under $200. I could then later get the CR-10 also and the Ender would still be useful to print wheels, tires, suspension etc while the bigger printer prints body parts. |

Nice work.
I'm a Sketchup junkie myself, which is fine for render quality work, but takes a ton of patience to prep for 3d Printing. It can be done, but not the best for any sort of production runs. I have Solidworks and Fusion 360 thru work, both are vastly better for engineer quality modeling and production, but Solidworks is a few grand. If it's something you want to really pursue, you may consider Fusion 360. I believe they still offer a free version for hobbyists, but even their pro version is reasonably priced. I'm also in Mid TN (live in Murfreesboro and work in Franklin) and have a filament style printer if you need to test some stuff out. It's an XYZ Davinci with an 8" cube print volume. |

I've been very interested in 3d printing. It started watching some of the 3d creations people were making here, which led me to start researching printers which led me to YouTube, after watching lots of videos by Joel the 3d printing nerd, Angus at Maker's Muse and Thomas Sanladerer. I really felt like it wasn't something over my head, I used to build and repair computers and laptops so I think I can build a kit printer, maintain and upgrade it no problem. (We'll see) I might take you up on that offer to test some things, have you been happy with the DaVinci? I have heard some mixed reviews on it. More progress on the model in the attachment |

Started building floor pans, and playing around with what to call this thing...

Finished floorpans and tailgate. Almost finished with the roll cage but it's giving me a few issues.
