Turn a clay model into an ergonomic 3D-printed pen using a 3D scanner


* This lesson is part of the PrintLab Classroom lesson portal. To purchase one-year access to 3D printing lesson plan portal, click here. *


This lesson plan is split into three one-hour sessions. Students will go through the 3D scan to 3D print processes to create an ergonomic pen. The lesson involves sketching, clay modeling, 3D scanning, CAD, and 3D printing. Enrolling in PrintLab Classroom will give you complete access to the teacher training material and lesson documents. This includes content to help you prepare and deliver the lesson along with design tutorials so you become familiar with the process prior to teaching it in the classroom.

Subject Areas

The lesson can be incorporated into the study of design technology, and art. The material can be adapted for ages 7-15.


Learning Criteria

In this lesson students will:

- Develop contextual knowledge of ergonomic design

- Improve their mastery of art and design skills using a range of materials

- Analyze and evaluate their own designs in order to determine whether they meet the criteria required for 3D scanning and 3D printing

- Develop hands-on 3D scanning skills

- Use CAD software to edit and prepare files for 3D printing

- Develop hands-on 3D printing skills

- Go through the product design process from concept to completion


Equipment List

Each student will require:

400g of air-drying white modeling clay (200g for session 1, 200g for session 2)—modeling tools are optional

1 x pen/pencil

1 x ruler

1 x Bic Cristal Biro Cartridge


The teacher will require:

1 x screen for presentation

1 x desktop 3D scanner (

1 x 3D printer and filament

1 x laptop/computer preloaded with 3D scanning software and 3D printing software

1 x ready-made clay model to run a 3D scanning demonstration

1 x 25mm diameter ball of pressure sensitive adhesive e.g. Blu Tack

1 x tube of superglue


* Parts of the lesson content show instructions on how to use the EinScan-SE 3D scanner. However the lesson can be adapted for use with other 3D scanners. *
