#3D Modeling questions / printer type to buy

Hello,

I recently started to use blender to make pokemon models I'd like to print out to make cute lil dioramas out of.

Stuff such as that lotad or that spheal.

Do i have to ensure all of my edited meshes have proper thickness, or does a closed mesh ( a volume with no filling and no thickness walls) get filled in entirely by the printer's software? Also do I need to unite all my meshes into one, or does intersecting ensure the printer will make a single piece?

For mid air stuff, do I add pillars, or does the software automatically insert some stuff that i can clean out post impression? (I've seen this happen with my old school's printer).

Lastly, which type of printer should I get? (I live in an apartment, so safety issues are a concern) . Do they come with their own software? Do I need additional gear?

If you have a rough idea of the price as well, my budget would be around 600$ for printer, brushes, materials, a fan and eventual additional gear

I'd appreciate any help / advice i can get!

Hello,

  1. It's generally recommended to ensure that your edited meshes have proper thickness before 3D printing, as printers may struggle with printing thin walls accurately. If you have a closed mesh, the printer's software may attempt to fill it in, but it's best to provide the thickness yourself for more control over the final result. While intersecting meshes can sometimes be printed as a single piece, unifying them can help ensure better printing results.

  2. For mid-air structures, it's a good practice to add supports or pillars in your modeling software before printing. While some slicing software can generate supports automatically, it's often better to manually add them for more precise control. You can then remove the supports post-printing.

  3. Considering your apartment setup and safety concerns, a good option could be a desktop FDM (Fused Deposition Modeling) or resin-based 3D printer. FDM printers are more common, safer, and easier to use at home. Some popular brands ...

What is Manifold Geometry
It is important that a model's mesh is manifold in order for a slicer to accurately determine where to generate a tool path to print plastic and where not to.

In relation to 3d printing a model is manifold when you could imagine filling the entire internal volume with water from one source. In practice this means that the model mesh has one single shell with no other shells that overlap or intersect with one another and the shell has no holes in it and the mesh has no flipped normals. You can think of a shell like that of an egg shell, it encloses a single volume of space. If there is more than one shell then filling any one shell the fluid cannot reach the other shells. If shells are nested within one another completely then the volume between the two shells can be filled. If shells partly overlap then only some of the volume of one or both of the shells can be filled. If shells have holes or flipped normals then the volume will leak water.

Slicers are universal, supports are automatic or manual if you want. Talking about FDM here.

What FDM Printer Should I Buy?
Use the #✅｜what-printer-should-i-buy if you're looking to buy a printer and seeking advice as to which.

Please provide the following info to help us help you decide:
• Your budget and country of residence
• Do you want to print special filaments? (flexible, high temperature resistance, high strength...)
• Do you want a kit or a mostly assembled machine?
• Are you willing to change parts on it and modify it to make it better? Or do you want something that is better out of the box? (More expensive)
• What size of printer do you require? (typical sizes go from 120x120x120mm to 300x300x300mm on average for consumer machines. Anything smaller or bigger is often not viable)
• Are there any special features you want? (quieter operation, enclosure, multicolour/multimaterial etc.)

Some printers are reviewed on the printers spreadsheet!

If you want resin, be aware of its dangers and need for proper ventilation (NOT an open window)

I see thank you

#

Is there a thing in blender which allows you to fix non manifold geometry?

#

Do I need to merge all meshes

# uncut narwhal Is there a thing in blender which allows you to fix non manifold geometry?
  • 3d printing toolbox addon
  • boolean modifiers, remeshing (voxel), and decimate (2 degrees)
  • merging all meshes will help... But i usually save a seperate version with _PRINT.blend in the naming where i clean up the mesh. In case I need to edit the original...
