# Filament Guide & Specs
Not all plastic is created equal. Always check the manufacturer's sticker on the spool, but use these general specs as a starting point.
## 1. PLA (Polylactic Acid)
The bread and butter of 3D printing. Made from corn starch.
> [!NOTE]
> **PLA Specs:**
> * **Nozzle Temp:** 190°C - 220°C
> * **Bed Temp:** 45°C - 60°C
> * **Cooling:** 100% Fan Speed
> * **Enclosure:** No (Keep door open)
* **Pros:** Easy to print, stiff, biodegradable.
* **Cons:** Low heat resistance (deforms in hot cars).
## 2. PETG
Strong, durable, and slightly flexible.
* **Best for:** Mechanical parts, outdoor items (UV resistant).
> [!NOTE]
> **PETG Specs:**
> * **Nozzle Temp:** 230°C - 250°C
> * **Bed Temp:** 70°C - 80°C
> * **Cooling:** 30% - 50% Fan Speed
> * **Enclosure:** Optional
> [!WARNING]
> PETG sticks **too well** to glass beds. Use a release agent (glue stick or hairspray) or it might rip chunks of glass out of your bed!
## 3. TPU (Flexibles)
Rubber-like material for tires, gaskets, and phone cases.
> [!NOTE]
> **TPU Specs:**
> * **Nozzle Temp:** 220°C - 240°C
> * **Bed Temp:** 50°C
> * **Speed:** VERY VERY SLOW (20-30mm/s)
## 4. ABS / ASA
The engineering standard. Strong and heat resistant.
> [!WARNING]
> **Safety Alert:** Printing ABS/ASA releases **Styrene**, a toxic gas. You MUST have an enclosure and proper ventilation.
> [!NOTE]
> **ABS/ASA Specs:**
> * **Nozzle Temp:** 240°C - 260°C
> * **Bed Temp:** 100°C - 110°C
> * **Cooling:** 0% Fan Speed (Off)
> * **Enclosure:** **REQUIRED** (or prints will warp/crack)
