Getting Started with 3D Printing

3D printing, also known as additive manufacturing, is a process of creating three-dimensional objects from a digital file. The most common method for hobbyists is Fused Deposition Modeling (FDM), where plastic filament is melted and deposited layer by layer to build up the object.

Unlike traditional manufacturing which removes material (subtractive), 3D printing adds material only where needed, reducing waste and enabling complex geometries impossible with other methods.

FDM (Fused Deposition Modeling)
- Most common for hobbyists
- Uses plastic filament (PLA, PETG, ABS)
- Affordable ($200-$2000)
- Great for functional parts

Resin (SLA/MSLA)
- Uses liquid photopolymer resin
- Higher detail than FDM
- Requires post-processing
- Best for miniatures and jewelry

Powder Bed (SLS)
- Industrial applications
- Nylon and metal parts
- No support structures needed
- Expensive ($10,000+)

Must Have:
- 3D Printer (FDM recommended for beginners)
- Filament (start with PLA)
- Computer with slicing software
- Scraper/spatula for removing prints
- Isopropyl alcohol for bed cleaning

Nice to Have:
- Deburring tool or craft knife
- Calipers for measuring
- Enclosure for ABS printing
- Filament dry box
- Spare nozzles

1. Level your bed - Most important step! Paper should slide with light resistance.
2. Download a test model - Try a calibration cube or benchy boat
3. Slice the model - Use PrusaSlicer, Cura, or BambuStudio
4. Start with recommended settings - Don't change everything at once
5. Watch the first layer - It determines 90% of success
6. Don't touch the printer - Let it finish without interference

Common first print issues:
- Warping: Bed not level or too cold
- Stringing: Temperature too high or retraction too low
- Layer separation: Temperature too low
