3D Printed Proof is a precision-focused FDM publication for people designing parts that must fit, move, assemble or meet dimensions reliably. Our central question is simple: did the printed part actually satisfy its dimensional and functional requirement?
A model can look correct on screen and still produce tight holes, loose joints, weak walls or distorted features. We focus on the practical decisions that help readers identify those problems, correct their causes and validate the finished part.
What We Cover
Our coverage is organized around Calibration & Accuracy, Fit & Tolerances, Strength & Walls, Geometry & Orientation, and Functional Features. These areas include dimensional calibration, clearances, hole sizing, wall behavior, print orientation, threads, joints and other geometry that affects real-world performance.
Current guides explain how to calibrate dimensional accuracy on an FDM printer and why 3D-printed holes come out too small. Planned coverage will extend these subjects with focused workflows, comparisons and technical explanations for functional FDM parts.
Our Editorial Approach
We aim to be measured, technical and practical. Exact recommendations depend on relevant conditions such as material, nozzle, layer height, orientation, machine and measurement method. Fit values from a specific test are useful evidence, not universal rules.
