Overview of Status of Analysis, Design, Fabrication, Tests, etc.
All components of the printer are nearly completed
Tested with 2D and 3D printing, both worked fine.
2D: Constant resolution stable print
3D: Managed to print a square up to 8 layers with constant resolution
More work required on wire management and insulation for fans/chamber
Accomplishments from Previous Week
Successfully 3D printed
Convective heating fans are done fabricating and works well
Goals for Next Week (list names after each item). Use specific and measurable objectives.
