3D printing has expanded into industries such as medicine, architecture, fashion, and manufacturing thanks to its versatility. However, not all 3D printers work the same way. Here's a look at the main types:
1. FDM (Fused Deposition Modeling)
This is the most common and affordable type. It uses plastic filament (PLA, ABS, PETG) that is melted and deposited layer by layer. Perfect for home use, rapid prototyping, and educational projects.
2. SLA (Stereolithography)
Uses a light-sensitive liquid resin that is solidified by a laser. It delivers high resolution and detail, making it ideal for dental, jewelry, and anatomical models.
3. SLS (Selective Laser Sintering)
This type fuses polymer powder (like nylon) with a laser. No supports are needed, making it great for functional and durable parts, often used in engineering and industrial design.
4. DLP (Digital Light Processing)
Similar to SLA, but uses a digital light projector as the light source. It’s faster and also produces fine details.
Selecting the right type of printer depends on your needs, budget, and desired level of detail. The 3D printing world keeps evolving, and each technology offers unique benefits.
