| 20:46 | < abudhabi> | What are commonly accepted blueprint formats in 3D printing? |
| 20:55 | <&ToxicFrog> | abudhabi: depends on what stage in the process, and what kind of printing. |
| 20:55 | <&ToxicFrog> | For FDM, the printer itself will almost invariably take g-code, a textual CNC instruction stream format. |
| 20:56 | <&ToxicFrog> | The slicer -- the tool that takes the 3d model and generates the c-code -- needs a tesselated mesh; STL is popular for this, and is what you should ship to end users. Don't ship g-code, since the generated code is printer- and material-specific. |
| 20:57 | <&ToxicFrog> | For the actual model editing, it depends on what software you use, but it can be basically anything as long as you can export it to a mesh when you're done. |
| 20:57 | < abudhabi> | I want to know what 3D printing businesses generally accept for their "print me this" service. |
| 20:57 | < abudhabi> | Hmm. |
| 20:57 | <&ToxicFrog> | They probably want the mesh, so STL or maybe OBJ. |
| 20:57 | < abudhabi> | Right. |
| 20:58 | <&ToxicFrog> | N.b. I assume that SLA and SLS print services will also use a mesh and just generate something other than gcode from the slicer, but don't quote me on that -- check the documentation for the print service. |
| 20:59 | < abudhabi> | Mhm. |
| 21:05 | < abudhabi> | OK, cool, freecad appears to export to a lot of formats, some of which look relevant. |

| 21:05 | < abudhabi> | I just have to learn how to use it. |
| 21:08 | < Alek> | oh hey, they stopped spamming? or did you finally figure out how to block them out? |
| 21:08 | <&ToxicFrog> | STL is really widely supported, I'm not surprised freecad can export to it. |
| 21:09 | <&ToxicFrog> | (I usually use openSCAD but my needs are pretty modest) |
| 21:09 | < abudhabi> | I suppose having a design will also possibly allow the option of using other manufacturing methods that support this. Like, wood. |
| 21:14 | < abudhabi> | Tamber: Is openSCAD easier to use? I need to design a solid object, no moving parts, no fine details, but moderately complex otherwise. |
| 21:15 | < abudhabi> | Ugh. |
| 21:15 | < abudhabi> | ToxicFrog: I meant you, not Tamber! |
| 21:15 | < abudhabi> | Specifically, what I'm going to be designing is a variation on #13 here: http://www.iz-article.ru/images6/sm2%205606.png |
| 21:17 | <&ToxicFrog> | OpenSCAD is the LaTeX of 3d modeling software. You write code that compiles to a 3d model. It works well with my brain but is definitely not for everyone. |
| 21:18 | < abudhabi> | Oh. I see. I'll take any graphical visualization over that. 😉 |
| 22:09 | <@gnolam> | ToxicFrog: the process for SLA is no different from FFM. You just get way bigger files (as the instructions are basically "full image of the layer + timing info"). |
