Solving Under-Extrusion Issues in Industrial 3D Printing
Under-extrusion is a critical issue in industrial 3D printing, leading to structural defects and compromising production quality. This article explores the main causes and advanced solutions to ensure precise and reliable prints while optimizing the production process.
What is Under-Extrusion in Industrial 3D Printing?
Under-extrusion occurs when a 3D printer fails to extrude enough material, compromising the strength and accuracy of the printed parts. This issue is particularly critical in industrial settings where print quality must be uniform and repeatable. Causes include incorrect parameters, nozzle or extruder defects, and filament-related issues.

How to Identify Under-Extrusion?
Identifying under-extrusion early is essential to avoid material waste and production delays. Symptoms include:
- Discontinuous or fragile layers
- Irregular surfaces with visible gaps
- Poor adhesion between layers
- Intermittent or insufficient extrusion
A visual inspection and precise measurements can help detect the issue before it affects production.
Common Causes of Under-Extrusion
The main factors causing under-extrusion in industrial environments include:
- Poor quality or contaminated filament
- Partially clogged nozzle
- Incorrect slicer parameters
- Inadequate printing temperature
- Incorrect filament feeding system tension
