An Analysis Of Tensile Test Results to Assess the Innovation Risk for an Additive Manufacturing Technology

Abstract

The aim of this study was to assess the innovation risk for an additive manufacturing process. The analysis was based on the results of static tensile tests obtained for specimens made of photocured resin. The assessment involved analyzing the measurement uncertainty by applying the FMEA method. The structure of the causes and effects of the discrepancies was illustrated using the Ishikawa diagram. The risk priority numbers were calculated. The uncertainty of the tensile test measurement was determined for three printing orientations. The results suggest that the material used to fabricate the tensile specimens shows clear anisotropy of the properties in relation to the printing direction.

Estimating the Approximation Uncertainty for Digital Materials Subjected to Stress Relaxation Tests

“…In [1], the uncertainty of tensile strength measurements was calculated taking into account three directions of printing of test pieces made of photo-cured resin (Vero White). The test results were used to assess the innovation risks for additive manufacturing.…”

Challenges of additive manufacturing technologies from an optimisation perspective

“…Unfortunately, material law implementation is not yet fully revisited leaving an open area for research in this direction [138]. A typical research direction would be to explore interfacial effect in terms of limited load transfer and damage kinetics at the light of results achieved for composite materials [139,140].…”

Experimental and simulation flow rate analysis of the 3/2 directional pneumatic valve

“…In terms of their manner of operation, they are divided into: electrically and mechanically operated, hand-or foot-operated, pneumatically operated via pressure increase/decrease, and spring operated valves. Taking the applied materials into consideration [1,2], valves are the most commonly classified as well into: aluminum valves, plastic valves, valves made of brass or other similar materials allowed in hazardous areas with risk of explosion, e.g. mines.…”
