PROBLEMS IN THE ADOPTION OF AM

Additive Manufacturing (AM) — the production method of the future — enjoys a rapidly growing market. As it undergoes major technological advances in quick succession its widespread adoption is certain. But of the companies that want to switch to AM:

www.spherene.one

71% say that a lack of knowledge* is the greatest limiting factor for AM

51% indicate the high cost* of 3D-printing as a challenge

75% indicate long time to finish* parts as a key challenge

* removal of build support

* long post processing time

* high material use

* long print times

* material waste

* low efficiency

* specialist skillset needed

* high design effort

* low innovation

HOW IT WORKS

Input parameters like shape, material or loads are translated into the ideal geometric form: an Adaptive Density Minimal Surface. ADMS approach maximum weight–to–performance ratio and are inherently printable without build supports. PATENT NR. PCT/EP2020/063727

TWO–CHAMBER SYSTEM

EFFECTIVE DISSIPATION OF STRESS & STRAIN NON-CONSTANT

ULTIMATE COMPRESSION PERFORMANCE

Shear and compression tests* show almost twice the specific stiffness and +98% superior compression for ADMS pitched against a ‹best in class› design provided by Zühlke Engineering. A random ADMS is as good as Zühlke’s best.

WHY ADMS ARE THE BEST POSSIBLE SOLUTION

ADMS have the same universal properties as the sphere — but the other way around. Nothing used in engineering today is similarly ideal.

NEW TECHNOLOGY FOR MEDICAL IMPLANTS: TITANIUM

Research at University of Applied Sciences FHNW Muttenz showed that ADMS provide support-free titanium SLM printing, superior strength, and no collapsing effect (versus the frequently used Gyroid Minimal Surface)

www.spherene.one

«It was shown that ADMS can be success-fully produced out of titanium by SLM without support structures, which is of great advantage for production and post-treatment.»

NEW TECHNOLOGY FOR MEDICAL IMPLANTS: BIOCERAMICS

In-vivo tests at University of Zürich confirmed exceptional bone ingrowth and vastly superior strength compared to their optimal design. ADMS offer excellent characteristics for implants and bone replacements printed from resorbable bioceramics.
