Assignments ​

Group Assignment ​

  • Test the design rules for your 3D printer(s)

Individual Assignment ​

  • Design and 3D print an object (small, few cm3, limited by printer time) that could not be made subtractively 3D scan an object (and optionally print it)

3D Print Design ​

3D Printer Status Indicator ​

This week, I designed and implemented an innovative 3D printer status indicator that uses intuitive visual cues to display the printer's real-time working status, enabling users to quickly assess print progress from a distance and enhancing overall work efficiency.

Design to Print Workflow ​

  1. Complete 3D modeling in Fusion 360 and export the design in STL format Model Export

  2. Complete slice settings and parameter optimization in Bambu Studio Slice Preview

  3. Print Results Display

Week Two Design Implementation ​

After completing the status indicator, I continued to print the model designed in week two. Following the same workflow, from 3D modeling to slicing to final printing:

  1. Model Slice Preview Slice Settings

  2. Printing Process Recording

3. Final Product Display

Assembly Complete

Infinite Cube ​

I designed an Infinity Cube model using Fusion 360. Due to the nested and interlocking nature of its internal structure, the model cannot be processed using traditional subtractive manufacturing methods (such as milling or turning) and can only be produced through additive manufacturing (e.g., 3D printing). Below is the detailed design process of the model.

The final printing effect is as follows:

3D Scanning ​

In this practice, I used the SHINING 3D EinStar series handheld 3D scanner. This is a professional-grade structured light 3D scanning device that uses blue light structured light technology to quickly and accurately acquire three-dimensional data of objects. I used this device to 3D scan and print a YOKE joystick. SHINING 3D

Operation Process ​

Software Preparation ​

Install the EXStar software. After installation, registration of a SHINING 3D account is required to activate the software features. The software interface clearly displays the complete workflow: device calibration, scanning acquisition, data post-processing, and dimensional measurement. Software Interface

Device Connection and Calibration ​

After connecting the scanner to the computer, create a new project in the software and complete the device calibration process following the system guidance to ensure scanning accuracy.

Scanning Data Acquisition ​

Considering the smooth surface of the YOKE joystick with insufficient feature points, markers were attached at appropriate positions to assist with scan positioning. During scanning, maintain a distance of 30-50cm between the device and the target object while performing a 360-degree scan to ensure data completeness.

After scanning, use the software's post-processing tools to optimize the model: Use the lasso tool to remove noise and excess data

After post-processing, complete the final model processing using the wrapping function After model processing is complete, click export data and select STL format
