SUNLU S1 Plus Filament Dryer Instruction Manual

Introduction

The SUNLU S1 Plus Filament Dryer is designed to remove moisture from 3D printer filaments, which can absorb humidity from the air. Drying filament helps prevent common printing issues such as stringing, clogging, and poor adhesion, leading to improved print quality and smoother model surfaces. This manual provides detailed instructions for the proper use and maintenance of your S1 Plus Filament Dryer.

Product Overview

The SUNLU S1 Plus features a built-in circulation fan for uniform heating, a 2-inch LCD screen for displaying temperature and time, and two control buttons for easy operation. It is compatible with various filament types and diameters.
