1-on-1 3D Printing Design Coaching: Advanced Parts That Print First Time

Each session the learner brings a design or a failed print. The tutor helps diagnose it and teaches the rule behind the fix: wall thickness, overhangs, tolerances for moving parts, or how orientation affects strength. The learner prints between sessions and reports back.

How classes work

Each 55-minute session is one learner with one teacher. There is no fixed lesson plan or set number of sessions: families book as many as they want, and the teacher sets the pace and focus around the learner's goals and gives feedback as they work.

What we can work on

• 

  Design and Printer Review – Look at past prints and set a project goal.

• 

  Walls, Overhangs and Bridges – Learn the limits of a printer and design within them.

• 

  Tolerances and Fit – Design two parts that slot together.

• 

  Moving Parts – Make a hinge or print-in-place joint.

• 

  Orientation and Strength – See how print direction changes strength.

• 

  Supports and Finish – Decide when supports are needed and how to avoid them.

• 

  Slicer Settings – Understand layer height, infill and speed.

• 

  Final Functional Part – Design, print and test a useful object.

Ages 12-17. Learners should already model in Tinkercad or Fusion 360 and have access to a 3D printer at home, school or a library.
