Practical Usage Tips for Optimal Printing

Mastering the Ultimaker S7 involves more than just knowing its specifications. Here are some practical tips to ensure the best possible print results:

• Filament Selection: The Ultimaker S7 boasts a wide range of compatible materials. However, selecting the right filament for your specific application is crucial. Consult Ultimaker’s material guides and community forums for optimized print profiles and recommended settings.
• Proper Filament Storage: Keep filaments dry! Most 3D printing materials are hygroscopic, meaning they absorb moisture from the air. This can lead to printing issues like stringing, popping, and weakened parts. Store filaments in airtight containers with desiccant packs.
• Bed Adhesion is Key: The Ultimaker S7’s flexible build plate with PEI coating provides excellent adhesion for most materials. However, for challenging materials like ABS or Nylon, consider using a brim or raft to increase the surface area in contact with the build plate and improve adhesion. Cleaning the build plate with isopropyl alcohol before each print is also essential.
• Nozzle Maintenance: Regularly clean your nozzles to prevent clogging and ensure consistent extrusion. Cold pulls (heating the nozzle, manually pulling out the filament) can remove stubborn clogs. Consider investing in nozzle cleaning needles for more intricate clogs.
• Experiment with Print Settings: Don’t be afraid to experiment with print settings in Ultimaker Cura. Adjusting parameters like print speed, infill density, and layer height can significantly impact print quality, strength, and printing time.
• Utilize the Built-in Air Filter: The integrated HEPA filter is designed to capture potentially harmful particles emitted during the printing process, especially when printing with materials like ABS. Ensure the filter is properly installed and replaced regularly according to the manufacturer’s recommendations.
• Keep Software Updated: Regularly update Ultimaker Cura and the printer’s firmware to take advantage of the latest features, bug fixes, and performance improvements.
