Markforged Print Accuracy

The precision of a 3D printed part from Markforged is influenced by various factors such as part geometry, fiber usage, chosen material, layer resolution, humidity, and machine condition. To achieve optimal dimensional accuracy for composite parts, it is recommended to adhere to the guidelines outlined in the Composites Design Guide during the printing process.

‍

Markforged composite printers have been shown to achieve high accuracy levels, falling within specified tolerance ranges as detailed below. 95% of measured values from multiple printers, builds, and features have fallen within these prescribed ranges according to internal testing and analysis.

‍

Desktop Series

X, Y Axis: +/-0.250 mm

Z Axis: +/- 0.100 mm or 0.15%

‍

Industrial Series

X, Y Axis: +/-0.100 mm or 0.2%

Z Axis: +/-0.100 mm or 0.1%

Important Notes:‍

1. Accuracy is based on measurements taken along the axes from multiple printers, builds, and features
2. The provided accuracy values represent the greater of the two measured aspects and are determined through internal testing of specific geometries printed using Onyx material with default 0.100mm layer height and print settings. Prior to measurement, the conditioning is performed consistently with ASTM D618 Procedure A
3. These values are applicable for printers manufactured after February 2021 and are reliant on proper maintenance procedures
4. The stated accuracy values pertain exclusively to Onyx prints; they are not applicable to Precise PLA or Smooth TPU prints
