Assignments & Goal#
Group assignment#
- do your lab’s safety training
- characterize your lasercutter’s focus, power, speed, rate, kerf, joint clearance and types
Individual assignments#
- cut something on the vinylcutter
- design, lasercut, and document a parametric construction kit, accounting for the lasercutter kerf
- extra credit: design it to be assembled in multiple ways
- extra credit: include elements that aren’t flat
- extra credit: engrave as well as cut
Learning outcomes#
- Demonstrate and describe parametric 2D modelling processes.
- Identify and explain processes involved in using the laser cutter.
- Develop, evaluate and construct a parametric construction kit.
- Identify and explain processes involved in using the vinyl cutter.
Refer to Assessment page
Group assignment guidline#
- Each lab should have at least 1 group assignment documentation (and show all student participated).
- IMPORTANT : Cite each week’s group assginment page in your individual Weekly Assignment Page.
【超重要】各々個人ページからグループページへのリンクをはること!
How to collaborate on same project on Gitlab#
- Method 1: Commit directly to the main branch
Same process as you upload your indivisual documentation.
Always make sure to pull remote and get the latest version before you edit.
You will encounter conflict if you edit the same line at the same time.
個人ページを更新するときと同じ手順です。編集する前に必ずPullしてください。同時に同じファイルの同じ行を編集するとコンフリクトが発生するので注意してください。
- Method 2: Branch out and send merge request
Effective way to keep track and organize when you’re working in a large group.
Reference : GitLab CE Tutorial #6 - Merge Requests
参考：Git Labでマージリクエスト（プルリクエスト）をするまで
Group assignment#
Check parameter, kerf width (spot diameter), precision and limitation of the laser-cutter in our lab.

Rico’s FreeCAD Tutorial on Parametric Design:#
via Rico
- Rough out a shape with a polyline drawing tool
- Apply constraints on the model to make it the actual shape you want
- Make Parameters
- Apply Parameters to the shape to make it fully-adjustable
- Extrude the 2D shape
- Apply Chamfers
- Export DXF file for cutting

Nueval#
The Evaluation Process (“Nueval”) is now active. Go to https://nueval.fabacademy.org/, and log in with your FabClout account.
The evaluation process:
- Students completes Weekly Assignment
- Students checks Checkboxes at Nueaval to indicate that the Local Evaluator can start.
- Local Evalutor evaluates and gives feedback.
- If the Local Evalutor suggests improvements, GOTO 1.
- If the Local Evaluation is at 100%, if will be handed off to an anoymous Global Evaluator
- Global Evaluator evaluates and gives feedback.
- If the Global Evalutor suggests improvements, GOTO 1.
- If all your Documentation is at 100% you have finished FabAcademy! Congratulations!
- Well, not quite. You still need to present in front of Neil and your Peers.
Overall Progress of Nueval.
