How 3D Printing Works (FDM)

Step Description
1. Design Create a 3D model using software (CAD) or download a pre-made file (STL).
2. Slice Use a slicer program to convert the 3D model into layers and generate G-code (printer instructions).
3. Print The printer heats plastic filament and extrudes it layer by layer onto a build plate.
4. Finish Remove supports, sand, paint, or assemble your 3D printed object.

Common 3D Printing Materials (Filaments)

Material Pros Cons Best For
PLA (Polylactic Acid) Easy to print, biodegradable Brittle, low heat resistance Decorative items, prototypes
PETG (Polyethylene Terephthalate Glycol) Durable, good layer adhesion Can string, requires higher temps Functional parts, outdoor use
ABS (Acrylonitrile Butadiene Styrene) Strong, heat resistant Warps easily, requires enclosure Mechanical parts, high-stress applications
TPU (Thermoplastic Polyurethane) Flexible, rubber-like Slow to print, can be tricky Flexible parts, phone cases
