Rapid Prototyping Services Project Background
With the popularity of smart homes and outdoor lifestyles, portable AI fans have become a new trend. Consumers not only need a lightweight and easy-to-carry design, but also seek smart features – such as voice control, mobile app to adjust wind speed, and even automatic adjustment of wind power according to the ambient temperature. Traditional manufacturing process is difficult to quickly prototype these complex structures, while 3D printing technology can accurately match the agile development needs of ‘design-test-iterate’.
Prototype Project Challenges
The design submitted by the client contained the following characteristics:
- Complex structure: internal hidden air ducts, foldable bracket, embedded sensor slots.
- Lightweight requirement: the weight of the whole machine needs to be less than 200 grams
- High surface texture: matte frosted texture + local glossy logo
- Functional verification: circuit board snaps and heat dissipation test space should be reserved.
If CNC processing is used, details such as folding joints need to be made and assembled in multiple parts, which will increase the cost by more than 3 times and make it impossible to realise integrated air duct testing. the ProtoMat team finally chose **SLA light-curing 3D printing technology**, which takes into account precision, speed and functionality.
The full process of 3D printing production
- 3D drawing analysis and intelligent disassembly
Disassemble the fan body into 6 modules: housing, blades, folding bracket, control panel, battery compartment cover, sensor bracket
- Ultra-precise printing
Adopting SLA600 DLC printer, 0.05mm layer thickness ensures smooth blade surface without layer pattern.
SLA 3d printed fan- Functional post-processing
Non-destructive sanding: 800-2000 grit sandpaper is used to treat the seams, preserving the original rounded corners.
Dual-colour painting: Matte black body + fluorescent green warning stripes
Intelligent components pre-installed:
Embedded touch screen test module in the control panel position to verify user interaction experience
Why choose 3D printing?
Cost and time comparison:
The cost of CNC machining is three times that of SLA 3D printing. CNC machining takes about 7 days, while SLA 3D printing only takes about 3 days.
Finished Product Results
The final prototype perfectly presents the design intention:
The mobile phone APP successfully connects and realises 6-speed wind speed adjustment.
Surface texture passed 95% of participants’ blind test.
The surface texture passed the blind test of 95% of participants.
