Frustrated with "subjective" flow rate calibration in OrcaSlicer? This quick guide will help you ditch the guesswork and objectively master your flow rate for consistently perfect prints.

Why Flow Rate Matters (The Short Version)​

Flow rate (Extrusion Multiplier, EM) controls how much filament your nozzle extrudes. Get it right, and your prints are strong, dimensionally accurate, and smooth. Get it wrong, and you'll face issues like:

• Over-extrusion: Wasted material, blobs, stringing, rough surfaces, weakened parts.
• Under-extrusion: Gaps, weak layers, poor surface finish, holes.

Introduction​

Flow rate calibration is a crucial step in achieving high-quality 3D prints. Proper flow rate ensures consistent layer deposition, smoother surfaces, and better details. In this article, which is one of a series of OrcaSlicer calibration articles, we’ll explore the flow rate calibration process using OrcaSlicer, an open-source slicer software designed for Fused Deposition Modeling (FDM) 3D printers.

Before we delve into the flow rate calibration process in OrcaSlicer, let's pause briefly to understand what it is and its key features.

OrcaSlicer: A Powerful & Flexible Option for 3D Printing Slicing​

OrcaSlicer is an open-source 3D printing slicer software for FDM printers. It's primarily designed for printers compatible with Marlin, Klipper, and Bambu Lab firmware. It supports various popular models from brands like Creality, Prusa, Elegoo, and even the open-source Voron.

OrcaSlicer Family Tree:​

OrcaSlicer is based on Bambu Studio, which itself is derived from PrusaSlicer. PrusaSlicer, in turn, is based on the open-source solution Slic3r.
