Our Manufacturing Standards

Implementing our manufacturing standards for Fused Deposition Modeling (FDM) 3D printing involves a comprehensive approach to ensure quality, consistency, and safety in the production process. This includes defining material specifications, calibrating machines, enforcing safety protocols, conducting quality checks, meticulous documentation, and continuous improvement efforts. Adhering to these standards ensures that printed parts meet specified criteria and fosters a reliable and efficient manufacturing process.

How Do We Implement Our Manufacturing Standards?

Here are the lists of standards we take into consideration.

• +/- a single build layer thickness for the first 2.5cm and +/- .100mm for every 2.5cm thereafter.

• .250mm layer thickness is used for parts fitting within a 250mm X 210mm footprint, (Prusa MK3S+)

• .300mm layer thickness is used for parts exceeding 350mm X 350mm footprint(Anycubic Chiron)

• .320mm layer thickness used for Prototyping PLA (250mm x 210mm x 210mm, Prusa MK3S desktop FFF)

• Guaranteed tolerances may be possible with a manual quote review and must be approved on a case-by-case basis.

• 3D Printcraft chooses optimal build orientation taking into consideration overall surface quality and minimum build time unless otherwise specified.

• Minimum resolvable feature size, including positive text features, is at least 0.89mm (1.14mm or greater is safest).

• Modeled threads or precision features may have limited functionality as printed. Tapping or the addition of threaded inserts is recommended for best function.

• Horizontal holes and protrusions will build slightly oblong due to stair stepping from layers.

• Nylon 12, ULTEM 9085, and ULTEM 1010 parts with thicker geometries, flat or broad parts, and parts with uneven wall thicknesses will be prone to significant deviations or warp due to variable thermal shrinkage and stress.

• General tolerances apply before secondary finishing or post-processing unless otherwise specified.
