Expert Guide: Optimizing Your Stratasys F123 Series 3D Printer for Peak Performance

Since its launch, the Stratasys F‑123 Series has become the industry’s go‑to solution for high‑quality, cost‑effective prototyping. In its first year it outpaced every previous Stratasys launch, proving that professional‑grade performance can be delivered without the hefty price tag of a production‑grade Fortus system.

At our Syracuse, New York headquarters the F370 powers our lab’s weekly production of prototypes, fixtures, and benchmark prints. Over the past year we’ve refined our workflow and gathered insights that we’re excited to share.

1. Dedicate Each Print Head to a Single Material

For maximum dimensional accuracy and reliability, assign one print head to each filament type. Switching from ASA to PC‑ABS, for example, requires a hardware swap and a fresh calibration. Skipping this step can lead to dimensional drift, stringing, or filament jams, potentially necessitating a full print head replacement.

2. Calibrate After Every Head Move or Unclamping

When a print head is moved or removed from its clamp, recalibrate the nozzle tip. This ensures the printer knows the precise distance from the tip to the build plate and the relative Z‑height between the model and support tips. Proper tip calibration guarantees flat bottoms, eliminates warping, and prevents the nozzle from dragging along the tray.

3. Keep Firmware Current

Stratasys released multiple firmware updates for the F123 Series in 2017. Machines without internet access can miss these improvements, which often include performance boosts and higher print detail. Regular firmware upgrades keep your F370 running at its best.

4. Replace Build Trays Frequently

While reusing trays may seem economical, repeated handling introduces oils and wear that compromise adhesion. For full trays or critical parts, always swap in a fresh tray to maintain consistent quality and avoid failed prints.

The F123 Series continues to be an invaluable tool for creating durable ASA and PC‑ABS prototypes, fixtures, and end‑use parts. By following these best practices, you’ll produce parts that look great and perform reliably.
