3D Printing with GeoGebra

Diego Lieban, Aug 16, 2018

Create your own 3D shapes with GeoGebra and a 3D printer. In this tutorial you will learn how easy it is to export 3D constructions from our [url=https://www.geogebra.org/3d]GeoGebra 3D Graphing app[/url] to the STL file format which can be printed directly on any 3D printer.

Tutorial for 3D printing with GeoGebra

[size=150][b]1)[/b][/size] Access [url=https://geogebra.org]geogebra.org [/url]and choose [b]3D Graphing.[/b]
[b][size=150]2)[/size][/b] At the top left corner, you must open the [b]Main Menu[/b] and then you can either create a [b]New[/b] file or [b]Open[/b] one that already exists.
[b][size=100][size=150]3)[/size][/size][/b] If you create a [b]New[/b] one, you can either do through geometric constructions or algebraic descriptions.
[size=85][size=100][i][color=#0000ff]note[/color][/i]: for those who are not familiar with proper GeoGebra algebraic syntax, we recommend starting from some examples available in [url=https://www.geogebra.org/m/pkfzccjw#chapter/314408]Samples[/url]. [/size][/size]
[b][size=100][size=150]4)[/size][/size][/b] If you select [b]Open[/b], just pick one up and click in [b]Edit[/b].
[size=100][i][color=#0000ff]note:[/color][/i] you can look for some materials through the [i]Search GeoGebra Materials[/i] bar. Typing [b]printable[/b], for instance, we got all options above.[/size]
[b][size=150]5)[/size][/b] Almost done! After your editions, you basically have to export to STL. Again in the Main Menu, select the option [b]Download as, [/b]choose[b] STL [/b]and finally[b] EXPORT [/b]your file. [br][br][i][color=#0000ff]NOTE[/color][/i]: Be sure all elements that you want to print out are visible in the main screen as well as those you don't want to print out must be deleted or hidden, like the axes for instance.
[size=150][b]6)[/b][/size] Next two final steps are out of GeoGebra. First, take a look if your STL is well done as the image in the left side bellow and then open it in your 3D software for final adjustments before you print out. You can find more details in [url=https://www.geogebra.org/material/edit/id/yaxnk8pd]Setting the 3D printer software[/url].
[i][b][color=#ff0000]REMARK[/color][/b]: [/i]you can also download as STL from others GGB apps, even though sometimes the way is a bit different. In [url=https://www.geogebra.org/classic]GeoGebra Classic[/url] for instance, the [b]Main Menu[/b] is now at the top-right corner. Then you'll find [b]Download as[/b] in the [b]File[/b] section, as shown below. Just explore it for other apps and have fun.

Technical Notes

Here you can find some comments on how to get good 3D printing results from GeoGebra.

  • 1. Dimensions and thicknesses
  • 2. Hiding undesirable objects
  • 3. Setting the 3D printer software

3.1.

Dimensions and thicknesses

Regardless of the dimension that you are modeling in GeoGebra, your model will be rescaled and exported to STL automatically with ~4 cm on its bigger dimension. For instance, if your model in GeoGebra looks like 6 x 6 x 8, then it will be exported to STL as 3 cm x 3cm x 4cm.[br][br]If you want something bigger or smaller than that, you can still rescale it in the 3D printer software. [br]The thickness of all objects in that case will be rescaled as well. By default, GeoGebra is exporting to STL under the follow dimensions:[br][br]ø 3.5 mm for curves and segments;[br]ø 3.8 mm for points; [br]~ 3.2 mm for surfaces. [br][br]You can find more details about that in [url=https://www.geogebra.org/m/pkfzccjw#material/yaxnk8pd]Setting the 3D printer software[/url].
