Extrudifier is a HTML5 application that enables you to create 8-bit pixel designs that can be exported into 3D models ready for 3D printing. Make coasters, fridge magnets and many other pixelated objects! Let your imagination run wild!

Frequently Asked Questions


Q: What is Extrudifier?
A: Extrudifier is a HTML5 application that uses <canvas> to enable you to create 2D designs that are then extruded to the height specified and converted into 3D models of various formats. These 3D models can then be 3D printed to make your designs into physical objects.

Q: What does extrude mean?
A: To extrude a 2D object is to pull it up in order to make it into a 3D object. Imagine your 2D design becoming a solid 3D object with a thickness that you specify with the height.

Q: What can I make with it?
A: You can make anything ranging from fridge magnets to coasters, keyrings, jewelery, etc. All you have to do is create your design, export it, tweak it in your favourite 3D modeling application and 3D print it.

Q: Where can I see some designs that have already been made?
A: I've put a number of designs that I've made using Extrudifier on Thingiverse in my Extrudifier Designs Collection. You can also do a search for any designs that have been tagged with Extrudifier.

Q: Is it free?
A: Yes, Extrudifier is free to use, feel free to spread the word if you like it!

Q: What file formats are supported?
A: There are three file formats that Extrudifer uses: Grid, SCAD and STL. The Grid format can be saved and loaded, whereas the SCAD and STL formats are export only.

Q: What is the Grid file format?
A: The Grid file format is a custom file format used by Extrudifier to save your design. This file format can be read by Extrudifer so you can save and continue working on your design at a later time.

Q: What is the SCAD file format?
A: The SCAD file format is used by OpenSCAD to represent solid models.

Q: What is the STL file format?
A: The STL (STereoLithography) file format is a popular 3D model file format that can be used by most 3D modeling tools. STL files can be imported directly into Cura ready for 3D printing.

Q: What does Generate Link do?
A: Generate link creates a URL (web site address) that can be used to share your Extrudifier design without saving it as a Grid file.

Q: What size grid does Extrudifier provide?
A: The grid is 32 x 32 pixels.

Q: Are there other grid sizes available?
A: At the moment Extrudifier does not support any other grid sizes. If this becomes a requested feature, it can be added in the future.

Q: What do the width/depth/height control?
A: These control the physical dimensions that the grid will have when 3D printed. The height is the extruded height of the 2D design, the width and depth are the dimensions along the X and Y axes.

Q: Can I submit suggestions and how?
A: Suggestions and feedback are always welcome and can be left on the Blog Post for Extrudifier. I would love to hear what you have to say.

Q: Will other file formats be supported?
A: There are no plans to support any other file formats in the near future because SCAD and STL formats cover the majority of the 3D formats used for 3D printing.

Q: Is GCODE file format supported?
A: GCODE is not supported and there are no plans to export into GCODE due to the number of different parameters that influence how GCODE files are generated.

Q: Why does Extrudifier not work on my browser?
A: Extrudifier requires a browser that supports HTML5 and the <canvas> tag. If your browser does not support those, Extrudifier will not run.

Q: Who made this useful tool?
A: Extrudifier was made by Igor Kromin, you can find my Blog here.

Q: Is Extrudifier actively developed?
A: Yes and no, the base functionality for Extrudifier is complete, if there are any suggestions that come up, I will be happy to implement them if I see them being useful.
