SGS Tested: 3D Materials with Superior Strength & Flexibility
When it comes to footwear innovation, performance is everything. At [PRINTMORROW], we believe that comfort, strength, and sustainability start from the material itself. That’s why our 3D-printed shoes are built on verified science — each batch of polymer materials undergoes rigorous mechanical testing by SGS, one of the world’s leading certification and testing authorities.
1. Verified by SGS: Certified Material Reliability
In March 2023, our core rubber polymer was officially tested by SGS-CSTC Standards Technical Services Co., Ltd. (Suzhou Branch) under the ASTM D2240-15(2021) and ASTM D638-22 standards.
The results speak for themselves:
| Test Item | Standard | Result |
|---|---|---|
| Shore Hardness | ASTM D2240-15(2021) | A/83 |
| Tensile Strength | ASTM D638-22 | 25.6 MPa |
| Elongation at Break | ASTM D638-22 | 244 % |
| Tensile Modulus | ASTM D638-22 | 25.2 MPa |
These figures confirm that our polymer combines high tensile strength and exceptional elasticity — a rare balance between durability and flexibility. In simpler terms, our 3D-printed shoes can stretch, support, and rebound without breaking down under daily wear.

2. What These Numbers Mean for You
-
25.6 MPa tensile strength means each shoe can withstand high pulling forces without deformation — ideal for running, walking, or daily commuting.
-
244 % elongation at break ensures flexibility and adaptability to your foot’s natural movement.
-
83 Shore hardness provides enough firmness for support while maintaining softness for all-day comfort.

This perfect balance results in a shoe that feels soft on impact yet strong under pressure, making it suitable for both lifestyle and athletic wear.
3. Inside the Science: How 3D Printing Enhances Performance
Our advanced HALS ultra-fast 3D printing technology allows precision lattice structures that optimize cushioning and airflow. Unlike traditional molded soles, every shoe layer is printed with micro-level accuracy — reducing material waste while maximizing ergonomic performance.
This synergy between tested materials and intelligent design means our shoes don’t just look futuristic — they perform that way.

4. Sustainable and Responsible Manufacturing
3D printing allows localized, on-demand production, minimizing excess inventory and shipping waste. Combined with our SGS-verified durable materials, the result is footwear that lasts longer and leaves a smaller footprint on the planet.
5. Proven Comfort, Certified Quality
Every pair of our 3D-printed shoes represents the fusion of engineering precision and real-world comfort.
SGS testing ensures that what we promise — flexibility, strength, and durability — is backed by internationally recognized standards.
Innovation isn’t just about design — it’s about trust.
When you choose [PRINTMORROW], you’re stepping into footwear that’s scientifically validated and sustainably crafted for everyday performance.
