Pro Tips

Partner with experienced resin suppliers like Colorado Sun Inc for consistent polymer quality and technical support in material selection and processing optimization.
Maintain detailed quality records for each filament lot to identify trends and correlate print performance with material properties over time.
Establish baseline performance metrics for each material type to quickly identify quality deviations and processing issues before they affect production.
Invest in proper drying equipment for hygroscopic materials like nylon and PETG - moisture control is critical for consistent mechanical properties.
Create material-specific print profiles based on quality testing results to optimize settings for each filament batch and maximize part quality.
