Managing Your Materials Library
Add filaments and resins, track stock levels, and keep cost-per-gram calculations accurate.
The Materials library stores every filament and resin you use. Each material has a cost-per-gram rate that feeds into your cost calculations, plus stock tracking so you know when to reorder.
Adding a Material
Go to Materials and click Add Material. Enter:
- Name — e.g., "eSUN PLA+ Black" or "Elegoo Standard Resin Grey"
- Type — PLA, PETG, ABS, TPU, Resin, Nylon, etc.
- Colour — hex value for visual identification
- Spool weight — net weight in grams (typically 1000g)
- Price per spool — what you pay
- Density — g/cm³ (PLA: 1.24, PETG: 1.27, ABS: 1.04)
- Current stock — number of spools on hand
- Low stock threshold — get alerted when stock drops below this
Cost Per Gram
Printforge automatically calculates the cost per gram from your spool price and weight. This is the rate used in the calculator. When spool prices change, update the price and the cost-per-gram updates everywhere.
Material Type Filter
The Materials page has a type filter dropdown. If you stock 30+ materials, filtering by type (PLA, PETG, etc.) keeps things manageable.
Colour Swatches
Each material shows a colour swatch based on the hex colour you entered. This helps visually identify materials in lists and the calculator dropdown.
