Trispatial Printer design documentation

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.

Layout of Documentation

This entry is to detail how I will be running this Log book.

Here is the layout this page will use for organization:

  1. Abstract:There will be a summary of the project at the beginning
  2. Layout: The layout of the page
  3. Design: Here I will detail the finalized designs
  4. Design Apparatus: Here I will present the most up-to-date Drawings and CAD models, numbered to correspond to the Theory
  5. Resources and Data: Here I will present information regarding my resources, lists of data for the project, etc.
  6. Final Build: Here I will detail any information on the final build
  7. Final Apparatus: Here I will present Pictures documenting the final build, numbered to correspond to text.
  8. Logbook: Here I will list the logbook entries.


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:

  1. All files begin with the first three letters of the Project name, in this case TRI.
  2. The second set of three digits represent the version I am on.
  3. The third set of three Letters represent the assembly within the project.
  4. The fourth set of three digits represents the part number within the assembly.
  5. The fifth set of three letters will state whether or not it is experimental (EXP) or final (FIN)
  6. 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.
  7. Example: TRI-007-EXT-004-EXP-C. This is read as: Trispatial, version 7, the extruder assembly, part 4, experimental, revision C.


The main requirements of the Gada Prize are:

  1. Print at least three different materials, including one that is usefully electrically conductive.
  2. Demonstrate the ability to print electronic circuit boards.
  3. Any print beds must be of a material which may be reused with minimal refurbishment for at least 20 print cycles.
  4. Maintain a total materials and parts cost under $200.
  5. 90% of the volume of the device's components shall be printed.
  6. Demonstrate a build volume greater than 300mm[11.81in] x 300mm[11.81in] x 100mm[3.94in].
  7. 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.
  8. The ability to print autonomously without a PC attached.
  9. Uses no more than 60 watts of electrical power.

Documentation Log Book

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 will help to keep this log book in order and will be generally adhered to throughout all levels of documentation.
  1. 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]
  2. There might not be new information in every entry subject
  3. I will update at least once a week.
