Allie[edit | edit source]

  • project writing

Bas[edit | edit source]

  • Take home exam MY5400: this will take all my time until Friday.


  • Software/firmware metal printer improve
  • HDPE prints experiments

Near term

  • linear_actuator:MOST
    • linear actuator stage w/game control - microscope -Science
  • Document the new design of the recyclebot and its operation-- main page Recyclebot - new designs here Recyclebot_v3.0, put images, detailed instructions for build and operate.
  • Background research on PETE -- its melting point is a lot hotter than what we have worked with - will be a challenge
  • custom reprap with high T extruder
  • print awesome parts
  • print mech tests components
  • PLA fractions experiment
  • print weak elec. material
  • large bot build/bed level/automate
  • resurrect trinity

Ben[edit | edit source]

Chenlong[edit | edit source]

Near term

* new glass etch - print Dr. Frost - verify - make sure it works on our own for PLA on normal glass

- The best recipe we have is:
- 1. clean slide with ethanol (200 proof is what we used)
- 2. soak in neat  [3-92-aminoethylamino)propyl]trimethoxysilane for 15 min.
- 3. rinse with toluene
- 4. let dry under ambient conditions over night

* ALD lit search Atomic layer deposition literature review

* finish InGaN lit review InGaN material characterization literature review

Emily[edit | edit source]

Near term - recyclebot

  • commission both filawinders
  • commission all 3 commercial recyclebots
  • read their spec sheets - if they can in theory do PET try it.
  • test PET in all bots with filawinder
  • when everything is good make good quality filament - while recording energy use and time for lca studies

Near term- microscope stage

  • finish on Automated microscope stage literature review - fill in spec sheet comparison chart with costs and do a lit. search on the instrumentation -- look for things like applications, etc.
  • Talk to Jerry about building it and doing test comparison with his
  • Create Spec sheet for the line of MOST OS automated microscope stage

Medium term

  • commission new recyclebot with Bas
  • test print with trinity with PET
  • when confident - we will do demo prints of OSAT
  • print dogbones for mech tests
  • do quick PET 3dp lit review

Medium - long term

  • lit review PET+ conductivity
  • order conductors
  • make composite filament
  • test composite filament
  • talk to Dr. King
  • print and test composite

Jerry[edit | edit source]


  • schedule/meet with Pat - see what is next
  • review stuff here - particularly build instructions and improve Open-source_metal_3-D_printer
  • order parts and make all metal MOST delta stage

Near term

  • collect data on delta 4 printing energy use for example product - I will send full list with paper outline
  • design and build table clamp for Nature stage
  • Nature -- develop protocols as a OS 3-D scientific platform: shaker, orbital shaker, mini shake table, particle size sorter, chem reactions, auto pippetter - work with Bas and Chenlong
  • write but dont post conversion of MOST delta to stage
    • write up BOM, instructions MOST delta stage
  • work with Bas to get fluid handling down by coupling syringe with stage

Ideas for later

    • talk to silabond see if they have anything useful
    • Methods paper on evaluating 3D printer materials - Nature/ Nature Materials
    • antigravity printing - space fabrication - top space journal?
    • zero waste laser/LED curing - Journal of cleaner production - can also take LCA route with David S.
    • surface finish printing - need killer app for this - then target the app
    • orthotics - with scanner - medical journal w. Mark
    • Effect of environment on print quality with exotic media
    • Silabond experiments
  • linear actuator stage w/game control - microscope -Science
  • Printing for Paul
    • methods paper on distributed casting - RepRap Journal
    • metal printer/ metal parts for it and Ga printing [1] or this [2]
  • inkject conductivity --Sci/Nature
  • pushme pullyou servo
  • glass fiber, sugar
  • WQI
  • work with portage
  • metal welder printer
  • possible PV characterization with Barbara

Joseph[edit | edit source]

near term

Jephias[edit | edit source]


  • 4 Point Probe:MOST
    • on the page put in the background material what is a 4 point probe, what does it do, how good does it have to be for our application
    • make a table of existing 4 point probes, costs, sources, specs -- use Emily's work on the syringe pump as an example

Near term

  • help Bas build 4 point probe
  • T up every experimental apparatus and write protocol for experiments when Ankit is done with simulations write appropedia "how to" pages for the following
    • Finish silver dep tests/protocol
    • start ITO tests/protocol
    • start litho tests/protocol
    • fix FIB protocol
  • Do it.

Nick[edit | edit source]

  • finish filter changer case
  • nip/pin flip stage
  • solar cell probe

Ravi[edit | edit source]

  • forestry data logger
  • Forest service PV system design-- appropedia summary page so others can copy - BOM, wiring, how to access data etc.
