PLA Temperature Tower (185–230°C)

A premium PLA temperature calibration tower designed by Craft & Hue for precise, real-world filament tuning. This tower covers 185°C to 230°C in 5°C steps and includes a full suite of structural tests to reveal the true performance of your filament.

A pre-configured G-code file is available in the Raw Files section of this listing. It already includes all temperature changes from 230°C down to 185°C in 5°C steps, so you can print the tower immediately without entering any manual commands.

Simply download it, load it into your Bambu printer, and you’re ready to go.

🔧 Features

- Temperature Steps (185 → 230°C) Clearly engraved labels for easy evaluation. - 45° and 55° Overhang Tests Instantly shows sagging, cooling behaviour, gloss changes and layer stability at each temperature. - Bridging + Arch Geometry Tests unsupported spans, dimensional accuracy, and heat softening in a realistic environment. - Smooth Calibration Surfaces Each fin provides clean planes for assessing layer consistency and surface finish.

🎯 What This Tower Helps You Determine

- Best printing temperature for your filament - Matte vs gloss transition point - Overhang behaviour at 45° and 55° - Stringing level at each temperature - Bridging performance - Layer adhesion - Detail reproduction and sharpness - Stability during long, thin overhangs Ideal for PLA, PLA+, Bambu Basic PLA, Matte PLA and most standard filaments.

🔥 Manual Temperature Change Instructions (Custom G-code)

If you prefer manual control over temperature stepping, add the following G-code commands in Bambu Studio → Right Panel → Custom G-code :

Command format:

M104 S[Target temperature] This sets the nozzle to the next temperature at specific layers.
