Tasks

Evaluate RAMBO fitness for purpose (can it handle enough current). Otherwise use RAMPS with drv8825. Set correct V_ref and steps per mm (drivers/firmware)

CAD l_module, including interfaces Order parts for l_module prototyping Design tests for l_module prototype Build l_module prototype Test l_module prototype, possibly iterate design Estimate costs for l_module design in $ and prep-time Record build time l_module (when built by non-developer)

CAD frame, including corner brackets Order parts for frame prototype Design tests for frame prototype Build frame prototype Test frame, possibly iterate design Estimate costs for frame design in $ and prep-time Record build time frame (when built by non-developer)

CAD the tool mount part, including bed probe Order parts for tool-mount prototype Design tests for tool-mount prototype Build tool-mount prototype Test tool-mount, (test reliability of bed probe) Estimate costs for tool-mount design in $ and prep-time Record build time tool-mount (when built by non-developer)

Order hot end for extruder prototype

CAD the tool extruder Order parts for extruder prototype Design tests for extruder prototype Build extruder prototype Test extruder, possibly iterate design Estimate costs for extruder design in $ and prep-time Record build time extruder (when built by non-developer)

Milestone: Build times for l_module, frame, tool mount and extruder recorded Milestone: All modules have module-tests created Milestone: All modules pass module-tests Milestone: First complete D3D Printer prototype built

Order Prusa Steel kits All instructors test out documentation and kit by building kit themselves

Define "workshop reprodicability" Define what data to collect during WS and how

Define which workstations should exist in WS (before WS1) For each workstation plan what hardware is needed Design testing procedures for each workstation Write instructions for each individual workstation Print out two sets of documentation for every workstation Plan and draw WS local layout and flows (workstations' relative placement and parts/participants-flow between them) Put chairs and tables in place in WS local Build complete example-printer and all example-modules for WS workstations (before WS1) Place example-modules, tools, instructions, test-rigs, nuts and bolts on workstations (before WS1) Create WS1 time schedule Simulate complete workshop (time: between USA arrival and first workshop)

Compile data-collection routine, build-steps, schedule, workshop local layout and hardware flows and welcome letter into one document: "WS1 Plans". This will evolve into project main delivery Milestone: First version of Workshop Plans released Send out WS1 Plans to participants

Host WS1 according to WS1 Plans Depending on type of data-collection: ask participants to fill out form. Milestone: First WS completed

Collect instructor experiences through WS retrospective/evaluation meeting From WS1 data determine bottlenecks for reproducability (cover at least build-process, participant satisfaction and instructor satisfaction). Compile "WS1 Experiences and Key Metrics", thesis quality, presented on wiki (Were Prusa Steel design suitable for paralell WS production?)

Do design improvements for D3D Printer for workshop (prepare design for WS2 action) Order for WS2:

 steel
 PLA filament
 stepper motors (and lead screws + coupler if not already lead screw shaft on motor)
 electronics
 endstops
 BuildTak or similar
 linear bearings
 smooth rods
 hot ends (with thermistor, resistor, maybe PTFE tubing)
 hobbed bolts
 nuts and screws
 power supplies
 Force Sensistive Resistors

Compile BOM for WS2 with sources and prices Print parts for WS2 Cut steel parts for WS2

Adjust WS local layout to match D3D Printer build (instead of Prusa Steel) Compile "WS2 Plans" Send out WS2 Plans to participants

Host WS2 according to WS2 Plans

Depending on type of data-collection: ask participants to fill out form. Collect instructor experiences through WS retrospective/evaluation meeting. From WS2 data determine bottlenecks for reproducability (cover at least build-process, participant satisfaction and instructor satisfaction). Compile "WS2 Experiences and Key Metrics", thesis quality, presented on wiki

Improve WS Plans Decide whether to use Prusa Steel or D3D Printer for remaining 2 workshops.

Prepare WS3 Host WS3 Compile "WS3 Experiences and Key Metrics", thesis quality, presented on wiki

Improve WS Plans

Prepare WS4 Host WS4 Torbjørn returns to Sweden Compile "WS4 Experiences and Key Metrics", thesis quality, presented on wiki Milestone: Four workshops hosted

Finish thesis Present

TODO: Copy relevant stuff from https://www.overleaf.com/read/vmpdtnzsgdgg over here...

TODO: Embed WBS here

TODO: Create team charter similar to this for Thesis Project...

TODO: Write Story from Background, Goal etc here, Google-Doc here and D3D Fusion Project Team Charter here. Focus on the tips I've got:

• Broader opening that explains main characters and concepts that builds the story
• Clearer links to earlier work

The super-project, D3D Fusion focuses on people and Distributive Enterprise. This thesis project focuses on the workshop, including the D3D Printer. Similarly to how the RepRap project focused on making any self-replicating 3D printer (not necessarily a fantastic 3D printer), this thesis will focus on creating workshop with self-propagating features.

This means tailoring a 3D printer design, creating an initial workshop plan and packaging it as a clone-able and easily modifiable kit. The core idea is to make an enterprise that spreads exponentially by mechanisms of self replication and evolution.

The evolution part is important: successful entrepreneurs share their versions of the workshop kit and will be replicated more often than the less successful attempts. This means we only need to reach the threshold of self-propagation before the kit starts to "improve itself". That is why we should focus on achieving the first propagation rather than perfecting a single part of the D3D Workshop Kit.
