Every result on this page is tested and documented — proof behind every print.
We employ repeatable, transparent, standard-inspired testing
protocols to evaluate 3D printing materials. Our methods bridge the
gap between laboratory precision and real-world maker
applications.
Our Testing Philosophy
We combine laboratory-style testing with real-world practicality to give makers,
engineers, and buyers clear, reliable material insights.
Repeatable
Controlled printing and testing conditions
ensure consistency across every material
we evaluate.
Transparent
We document our methods, settings, and
results so you know exactly how we test
and score.
Standard-Inspired
The line height in the live website differs from the value specified in the Figma design.
Practical
We focus on what matters in real prints—
printability, durability, and long-term
usefulness.
Visual & Clear
Results are shown in easy-to-understand
scorecards, charts, photos, and real
examples.
For Everyone
Built for creators, engineers, designers,
and buyers who need evidence, not
marketing claims.
Our testing methodology
Standard-inspired. Repeatable. Transparent.
1
Material Intake & Preparation
Materials are logged, dried (if
needed), and printed using
controlled processes to ensure
consistency.
2
Standard-Inspired Testing
Mechanical, thermal, and physical
tests are performed using standard-
inspired protocols.
3
Data Analysis & Scoring
Results are analyzed, normalized,
and scored across key performance
categories.
4
Documentation & Publication
Scorecards, reports, photos, and
results are published with full
transparency.
- While PrintProof Lab is not a certified testing laboratory, all tests are performed using documented, standard-inspired methods to provide consistent and transparent material evaluations.
Key performance Test
Printability
Ease of printing, layer consistency, reliability, and common issues.
Dimensional Accuracy
How closely prints match
intended dimensions and
tolerances.
Tensile Strength
Material strength under tension
and resistance to breaking.
Layer Adhesion
Bond strength between layers
and resistance to delamination.
Flexural Strength
Bending performance and
stiffness under flexural load.
Heat Resistance
Resistance to heat deformation
and ability to maintain properties.
Creep Resistance
Ability to resist deformation
under long-term load or stress.
Impact Resistance
How well the material absorbs
energy and resists impact.
Moisture Stability
Effect of moisture exposure and
drying on print quality and
strength.
Surface Quality
Visual finish, layer lines,
smoothness, and overall surface
appearance.
Additional tests may be carried out depending on the material type, supplier claims, and intended application. These may include hardness, UV/weathering, chemical exposure, abrasion, flexibility, conductivity, or other material-specific checks.
