Here is an update and release of the universal 3D Printing Filament Spool Standard.


The Idea was first discussed and proposed here in March 2014, the draft standard has now been produced for comment and further discussion. It's available for download from the 3D Printing Association and Youmagine.

If you wish to discuss, comment or ask questions about the standard, a Youmagine page also contains the standard and can accommodate any drawings, model files or tooling information as required.

To get you up-to-speed quickly take a look at the original blog post here, and also view my update video on Youtube or below.



The discussion thread on the RepRap Forum is also still alive and active if you prefer to keep that discussion going.

The document standard is - Document Number - 88-22963-1 (Issue 1) 25th November 2014

The 3D Printing Association is supporting this project and also looking for feedback and implementation from filament manufacturers and everyone in the 3D Printing community, please get involved if you can.

 Expanded Biofoam (PLA based) half-spool - can be rotated together to form a Filament spool.


Dimensions are outlined in the spool standard along with suggested deviations.



Space reduction was an important factor for the spools, both is shipping weight and the volume of space the take up while in storage before being used to hold 3D Printing filament.




The idea of a standard filament spool size and compatible mechanical mounting dimensions will only be a reality of filament manufacturers decide to work with the standard and help make it a success.

Thanks for reading, and a special thank you to all of you who got involved in this and spared time to talk to me, I really appreciate it.

The 3D Printing community thanks you all.

Rich.
