Your filament spool says "print at 190-220°C." That's a 30-degree range. Which number do you actually use?

The answer is different for every brand, every color, and sometimes every batch. A 3D print temperature tower finds the exact sweet spot in one short print. It takes 15-30 minutes, uses a few grams of filament, and gives you a clear visual answer you can see with your eyes.

## What Is a Temperature Tower?

A temperature tower (also called a temp tower or heat tower) is a test model divided into sections stacked vertically. Each section prints at a different nozzle temperature. The model typically includes features that reveal temperature problems: small bridges, gaps between pillars (for [stringing](https://beginner3dprinter.com/3d-print-stringing/) tests), overhangs, and fine details.

After printing, you compare sections visually. The section with the cleanest bridges, least stringing, and smoothest surface tells you your optimal temperature.

One print, one answer, done.

## Where to Download a Temperature Tower STL

Many slicers now have built-in temperature towers (see below), so you may not need to download anything. But if you want a standalone temperature tower STL file:

- **MakerWorld** (makerworld.com): Search "temperature tower" for dozens of options. Recommended: Smart Compact Tower (smaller, prints faster)
- **Printables**: Search "temp tower" for community designs with various features
- **Thingiverse**: Classic option, many variations available

Pick one that matches your material range. PLA towers typically span 190-220°C. PETG towers span 220-250°C.

## How to Print a Temperature Tower in Bambu Studio

Bambu Studio has a built-in calibration feature. No STL download or manual G-code editing needed.

**Steps:**

1. Open Bambu Studio
2. Top menu: **Calibration > Temperature**
3. Select your filament type (PLA, PETG, etc.)
4. The software automatically generates a temperature tower with the correct range
5. Click **Print** (sends directly to your Bambu Lab printer)

That's it. The printer handles the temperature changes automatically at each layer height. After printing, compare sections and note the best temperature.

This is the easiest method if you own a 3D printer temp tower workflow on a Bambu Lab machine. The entire process takes under 2 minutes of your time (plus print time).

## How to Print a Temperature Tower in Orca Slicer

Orca Slicer (popular with Klipper printers and as a Bambu Studio alternative) also has a built-in generator.

**Steps:**

1. Open Orca Slicer
2. Top menu: **Calibration > Temp Tower**
3. Set **Start Temperature** (e.g., 220°C for PLA) and **End Temperature** (e.g., 190°C)
4. Set **Step** (usually 5°C per section)
5. Click **OK**. The orca slicer temp tower generates automatically on the build plate
6. Slice and print

Orca handles the G-code temperature changes for you. No scripts or plugins needed.

## How to Print a Temperature Tower in Cura

Cura requires a few more steps because it doesn't auto-generate the tower. You'll import a downloaded STL and add a temperature-change script.

**Steps:**

1. Download a temperature tower STL (from MakerWorld or Printables)
2. Import it into Cura (drag onto build plate)
3. Slice the model normally
4. Go to **Extensions > Post Processing > Modify G-Code**
5. Click **Add a script > ChangeAtZ** (or "TempFanTower" if available)
6. For each section, set the layer height where temperature should change and the target temperature
7. Re-slice and print

**Simpler alternative for Cura:** Search MakerWorld for "Cura temp tower pre-configured" with embedded temperature changes already in the model. Some creators upload versions that don't need scripts.

This method works for all Creality printers (Ender 3, K1, Neptune) and any printer using Cura.

**PrusaSlicer users:** Import the STL, then right-click the model > Add Height Range Modifier. Set a different temperature for each height range matching the tower sections.

## Recommended Temperature Ranges by Material

| Material | Test Range | Step | Typical Best Temp |
| -------- | ---------- | ---- | ----------------- |
| **PLA**  | 190-220°C  | 5°C  | 195-210°C         |
| **PETG** | 220-250°C  | 5°C  | 230-240°C         |
| **ABS**  | 230-260°C  | 5°C  | 240-250°C         |
| **TPU**  | 210-240°C  | 5°C  | 220-230°C         |

**Note on brand differences:** Don't assume all PLA is the same. Bambu Lab PLA Basic prints beautifully at 200°C. eSun PLA+ often needs 210°C. Polymaker PolyTerra prefers 195°C. Even different colors within the same brand can vary by 5°C (darker pigments sometimes need slightly higher temperatures). A PLA temp tower takes 20 minutes and removes all guesswork.

For PETG specifically: this material is naturally stringy. Your PETG temp tower will likely have some stringing at every temperature. The goal is finding the temperature with the least stringing while maintaining good layer adhesion. Don't chase "zero strings" with PETG because dropping temperature too low causes layer splitting.

## How to Read Your Temperature Tower Results

Look at each section and evaluate these four things:

**1\. Stringing (threads between pillars/gaps)** Less is better. The section with the fewest thin strings between features is closer to your ideal temperature. Stringing means temperature is too high for that section.

**2\. Bridging (horizontal spans with no support)** Flatter is better. If the bridge droops or sags badly, the temperature is too high (filament too liquid to hold shape mid-air). A clean, flat bridge means the filament solidifies quickly enough.

**3\. Surface smoothness** Run your finger along each section's outer wall. The smoothest section with no bumps, blobs, or rough texture is printing at a good temperature.

**4\. Layer adhesion (optional destructive test)** Try snapping a section off. If it breaks cleanly between layers with minimal force, the temperature was too low for proper layer bonding. Good adhesion means layers fuse together strongly.

**How to pick the winner:** Find the section that scores best across all four criteria. If two sections look equally good, pick the lower temperature (less stringing, less energy, less oozing overall).

## What to Do After Finding Your Best Temperature

Once you know the optimal temperature:

1. **Update your filament profile** in your slicer. In Bambu Studio: go to the Filament settings tab, change nozzle temperature, and save as a new preset (name it with the brand and color, e.g., "eSun PLA+ White 210°C")
2. **Label the spool.** Write the optimal temperature on the spool with a marker so you don't forget
3. **Test new spools.** Even the same brand and color from a different manufacturing batch can shift 5°C. If a new spool [isn't sticking well](https://beginner3dprinter.com/3d-print-not-sticking-to-bed/) or has unexpected stringing, re-run a temp tower before tweaking other settings

A temperature tower is your first troubleshooting step whenever print quality drops with a specific filament type. Before adjusting retraction, speed, or flow rate, confirm your temperature is still dialed in.

## FAQ

### What temperature should I print PLA at?

Most PLA prints best between 195-210°C, but it varies by brand. The spool label gives a range (e.g., 190-220°C). Print a temperature tower to find the exact best value for your specific spool on your specific machine. It takes 20 minutes and removes all guessing.

### Do I need a temperature tower for every new filament?

Ideally, yes, especially when trying a new brand or material. Same-brand, same-color filament from the same purchase is usually consistent enough to skip. But if you open a new brand or even a noticeably different color from your usual, 20 minutes for a temp tower saves hours of troubleshooting later.

### My temperature tower looks the same at every level. What's wrong?

Two possibilities: (1) The temperature isn't actually changing between sections, meaning the G-code script didn't apply correctly. Re-check your slicer's post-processing setup. (2) Your filament is moisture-damaged, which causes consistent poor quality regardless of temperature. Try drying the spool first, then reprint the tower.
