Builder Premium Medium

The Builder Premium Medium is an FDM 3D printer from Builder with a 210 x 210 x 400 mm build volume.

Specifications

In the professional desktop FDM 3D printing segment, the Dutch manufacturer Builder 3D Printers has carved out a unique engineering niche. The Builder Premium Medium sits in the center of their Premium product line, offering a substantial vertical print volume, a fully enclosed chamber, and a patented Dual-Feed extrusion technology. The machine is targeted directly at rapid prototyping in corporate environments, architectural design firms, and design studios where high mechanical reliability, multi-material capabilities (particularly soluble support integration), and very quiet operational characteristics are required.

• Hotend: Patented Builder Dual-Feed hotend assembly.

Calibration

Operating the unique Dual-Feed system of the Builder Premium Medium requires specific calibration routines to prevent mechanical blockages and maintain color integrity. Follow these 8 calibration steps:

• Extruder E-steps Calibration (Dual Feeds)

Both feed motors must feed the exact same volume of filament. Any difference in feeding velocity will lead to pressure imbalances in the nozzle when switching between channels.

Common defects

• Hardware defects and mechanical weaknesses
• PVA Thermal Degradation Jams: PVA is highly sensitive to heat. If the inactive channel is kept at print temperature (above 200°C) during long prints, the PVA inside will carbonize and form a plug.
• Solution: Always set a Standby Temperature for the inactive extruder to 150-160°C in your slicer settings.

What it is used for

Best applications:

• Tall PLA Prototypes (up to 400 mm): Ideal for printing bottle prototypes, architectural columns, tall enclosures, and decorative structures.
• Soluble-Support PLA Models: Well-suited for complex visual models with internal channels where mechanical support removal is impossible.
