Trispatial is a 3D printing device being developed as an entry for the Kartik M. Gada Personal Manufacturing Prize. The current stage is still early development and design.
Contents
Overview
The main requirements of the Gada Prize are:
- Print at least three different materials, including one that is usefully electrically conductive.
- Demonstrate the ability to print electronic circuit boards.
- Any print beds must be of a material which may be reused with minimal refurbishment for at least 20 print cycles.
- Maintain a total materials and parts cost under $200.
- 90% of the volume of the device's components shall be printed.
- Demonstrate a build volume greater than 300mm[11.81in] x 300mm[11.81in] x 100mm[3.94in].
- The capacity to print a full set of components for a complete replica of itself within 10 days unattended save for clearing no more than one printer head jam.
- The ability to print autonomously without a PC attached.
- Uses no more than 60 watts of electrical power.

Nomenclature
As was stated by Isaac Olson "Due to the nature and scale of this project it is expected that hundreds – if not thousands – of files will be created to properly document and exploit the various conceptual designs, prototypes, and official releases. Because one can only name a file just so many things before language is exhausted, the following nomenclature will be used...". Similarly, I will also use a naming system much like Columbus
My naming system will be:
- TRI-XXX-XXX-XXX-X
- All files begin with the first three letters of the Team name, in this case TRI.
- The second set of three digits represent the project the component is in.
- If a file is purely experimental then it may be noted as such by substituting the project name with "EXP". Example: TRI-EXP-580-...
- The third set of three digits represent the assembly within the project.
- The fourth set of three digits represents the part number within the assembly.
- The last placeholder represents the release status: an uppercase letter for released revisions (A,B,C...) or a number for unreleased revisions (1,2,3...)
- For released revisions the letters I (as in iceberg) and O (as in orange) are skipped due to their similar appearance to 1 and 0 respectively.
- Example: TRI-345-007-004-C. This is read as: Trispatial, project 345, assembly 7, part 4, revision C.
I will probably change this further, but for now I will use this. However, if anybody dislikes my use of this system I will be happy to change it.

General Notes
In cooperation with the official rules, all documentation for this project will be displayed here. In addition to this wiki I will have a web log documenting in parallel. However, nothing on the web log will differ from the documentation here, and anything that does should be considered insignificant.
- The following notes help to keep this workbook in a neat and orderly condition and shall be generally adhered to throughout all levels of documentation.
- All dimension and temperature nomenclature shall include both SI and Imperial units. SI units shall be first followed by Imperial units in brackets. Examples: 100mm[3.94in] and 40°C[104°F]
