TEST SETUP
----------
- Print ASTM-type dogbone coupons (use provided G-code)
- 100% infill, rectilinear pattern
- Nozzle: 0.4mm, Layer height: 0.2mm
- Calibrate extruder steps/mm first
- Print at least 5 samples per material

PRINTING PARAMETERS
-------------------
Material | Nozzle Temp | Bed Temp | Speed      | Retraction
---------------------------------------------------------------
PLA      | 210°C      | 60°C     | 60 mm/s    | 4-6mm @ 40-50mm/s
PETG     | 235°C      | 80°C     | 40 mm/s    | 6mm @ 40mm/s
ASA      | 260°C      | 100°C    | 50 mm/s    | 6-8mm @ 40mm/s

TESTING PROCEDURE
-----------------
1. Condition samples for 24 hours at 22°C, 50% RH
2. Measure cross-sectional area of neck section
3. Mount in tensile testing machine with appropriate grips
4. Apply load at constant rate (5mm/min)
5. Record maximum load at failure (in Newtons)
6. Calculate stress: Force (N) / Area (mm²)

EXPECTED VALUES (from CNC Kitchen)
-----------------------------------
PLA: 318 N average tensile strength, 3.2% elongation
PETG: 405 N average tensile strength, 12.8% elongation
ASA: 472 N average tensile strength, 8.5% elongation

SAFETY
------
- Wear safety glasses
- Clamp samples securely
- ASA printing requires ventilation (fumes)
