S7 Pro Bundle

The S7 Pro Bundle is an FDM 3D printer from UltiMaker with a 330 x 240 x 300 mm build volume.

Calibration

• Verify the machine state before any calibration run.

Action: Power on the S7 Pro Bundle, confirm the build chamber is clean, ensure the PEI plate is seated flat on the magnetic base, and verify that the active print core pair matches the intended job. For dual-material work, install the correct AA/BB/CC combination and make sure the purge bucket and front material bays in the Material Station are unobstructed.

Common defects

• First-layer adhesion sensitivity can still appear if the build plate is contaminated or the wrong profile is used. The S7’s PEI flexible plate was introduced specifically because UltiMaker identified poor first-layer adhesion as a major failure source, and the company claimed a substantial reduction in adhesion-related defects after the switch.

Symptoms: Corners lifting, incomplete brim bonding, shifting first layers, or parts detaching mid-print.

What it is used for

The UltiMaker S7 Pro Bundle is best suited to reliable professional FDM production, especially when unattended operation, dual-material printing, and controlled environmental stability matter more than maximum raw speed.
