Quality

At 3DFils, we know that filament quality is critical for achieving precise and consistent 3D prints. Every filament specification—whether its diameter, tolerance, or ovality—exists for a reason: to ensure the material performs exactly as expected in the printer.

To achieve this, we developed checkFIL , a real-time control system that monitors every stage of the manufacturing process. This way, each reel is tracked from raw material to final product, ensuring it remains within established tolerances.

Key quality parameters:

Diameter

Diameter is the measurement from one end of the filament to the other in a cross-section. Filaments typically come in standard sizes, such as 1.75 mm or 2.85 mm.

Tolerance

A tolerance, for example ±0.05mm, indicates how much that diameter can vary on each spool. In other words, a 1.75mm filament measuring ±0.05mm can vary between 1.70mm and 1.80mm. Although the difference may seem minimal, in 3D printing terms this translates into significant variations that can affect extrusion accuracy.

Ovality

Ovality assesses whether the filament maintains a perfectly circular shape throughout its entire length. A filament that deforms and becomes oval can cause difficulties for the printer's feed system to properly grasp it, leading to problems such as overextrusion or even jamming.

Measurement of diameter and ovality

Standard Deviation

We measure the variation in diameter along the filament. A low standard deviation means that most sections of the filament are close to the ideal value, resulting in a more uniform and predictable material.

Standard Deviation of the filament

What quality do we offer?

Our coils meet at least these parameters:

Maximum tolerance: < 0.05mm
Ovality: <2%
Standard deviation: <0.02mm

These values ​​are for reference only and may vary depending on the material and specific diameter. For exact quality, please refer to the respective product page.

Check the Quality for Yourself

3DFils Quality Label

Each reel includes a label with all the quality data and a unique identifier, allowing each stage to be tracked from manufacturing to delivery.

Final Filament Inspection

Before the filament is wound, it undergoes rigorous quality control using an advanced laser inspection system. This high-precision system performs real-time measurements of the filament's diameter and ovality, continuously evaluating each section to ensure it remains within established specifications (1.75 mm or 2.85 mm). This ensures that the material meets the standards necessary to deliver optimal performance in 3D printing applications.

The laser performs multiple measurements per second, allowing each segment of the filament to be analyzed thoroughly and without error. Thanks to this high evaluation frequency, even the most subtle variations in diameter or shape are detected instantly, preventing tiny defects from propagating throughout the material.

As soon as any anomaly is identified, the system triggers an immediate alert. This rapid response mechanism ensures that any spool that deviates from quality parameters is discarded from the production line. This protects the end user from potential issues during 3D printing, ensuring that only filament that strictly meets specifications reaches the market.

How Does Low Quality Affect 3D Prints?

A difference in diameter or high ovality can cause serious problems during printing:

  • The printer may extrude too much or too little, creating gaps or excess material.
  • The extruder can clog if the filament is not fed consistently.
  • Adhesion between layers can be compromised, affecting the strength and finish of the part.
  • Printing software, which uses filament dimensions to calculate extrusion, relies on these measurements; any discrepancies can throw the process off.

Therefore, investing in high-quality filament not only improves the quality of your prints, but also prevents problems that could lead to additional costs for rework or repairs.
