3D Filament vs. Resin
This course provides an in-depth exploration of the two primary 3D printing material categories—thermoplastic filaments (FDM/FFF) and photopolymer resins (SLA/DLP/LCD). Students will learn the properties, applications, advantages, and limitations of each material type, along with practical guidance on selecting the right medium for different projects.
By the end of this course, learners will be able to:
- Identify key differences between filament and resin-based 3D printing.
- Select appropriate materials for functional, aesthetic, or industrial applications.
- Understand post-processing techniques (sanding, curing, etc.) for each material.
- Troubleshoot common printing issues related to material choice.
- Apply safety best practices when handling resins or high-temperature filaments.
