PRODUCTION
Production of Roffesen 3D is located in Surany, Slovakia. This factory has many years of extrusion experience at the highest standards.

QUALITY AS PRIORITY
For Roffelsen 3D, quality is one of the core values. Quality of the products and production, as well as the services. The production lines are equipped with state-of-the-art measuring instruments that continuously monitor quality. ISO9001 certification of our factory in Slovakia helps to ensure the high quality standard.
Roffelsen 3D printing filament is manufactured to meet the highest performance specifications.
Filament Quality Assurance
In-Line Measurement of filament dimensions
The filament diameter and roundness are major factors which influence ease and consistency of printing and the quality of your end-product. Too high fluctuations in filament diameter will result in over- or under extrusion, which will affect the dimension tolerances and mechanical properties of the printed product
Roffelsen 3D uses 3-axis laser scans the filament 5000 times per second as it is being produced, resulting in an unrivaled diameter and ovality tolerance. Many other 3D printer filament manufacturers only measure after the filament has been produced using a small sampling of the total production. Our filament is guaranteed to be within +/- 0.05mm of the stated diameter. Quality reports on filament dimensional tolerance can be supplied per produced spool on request.
Test Prints
Each batch of filament is rigorously tested in the field using desktop 3D printers to ensure that melting temperatures and surface finish are consistent and of the highest quality.
Traceability
Raw materials are checked prior to production and full traceability is guaranteed per spool.
Roffelsen 3D stores filament samples of each produced batch to trace and check product consistency over time.





Granulate quality assurance
Certficates of Analyses
For each produced batch, we can supply a tailored Certificate of Analysis, with test results of key material properties of the produced batch.
Traceability
Raw materials are checked prior to production and full traceability is guaranteed per produced batch.
