Analysis of the Part Distortions for Inconel 718 SLM: A Case Study on the NIST Test Artifact
(MDPI, 2020-11-11)
The present paper evaluates the misalignment and geometry distortion of the standard National Institute of Standards and Technology (NIST) test artifact in Inconel 718 alloy, when several layers with and without supports ...
Functionally Graded AISI 316L and AISI H13 Manufactured by L-DED for Die and Mould Applications
(MDPI, 2021-01-15)
Tooling in the die and mould industry is subjected to high-wear and high-temperature environments, which often leads to the premature failure of this high-added-value tooling. When severe damage occurs, an alternative to ...
Influence of process parameters on the particle-matrix interaction of WC-Co metal matrix composites produced by laser-directed energy deposition
(Elsevier, 2022-11)
The prediction of the in-service behaviour of metal-matrix composites produced by laser-directed energy deposition is a fundamental challenge in additive manufacturing. The interaction between the reinforce-ment phase and ...
Effect of powder particle size distribution on the surface finish of components manufactured by laser powder bed fusion
(Springer, 2023)
One of the key aspects of the laser powder bed fusion (L-PBF) process is the quality of the raw powder since it affects the final properties of the manufactured parts. In this study, 13 batches of Inconel (R) 718 powder ...
The Effect of the Laser Incidence Angle in the Surface of L-PBF Processed Parts
(MDPI, 2020-10-24)
The manufacture of multiple parts on the same platform is a common procedure in the Laser Powder Bed Fusion (L-PBF) process. The main advantage is that the entire working volume of the machine is used and a greater number ...
Modeling of cutting force and final thickness for low stiffness 2024-T3 aluminum alloy part milling considering its geometry and fixtures
(Elsevier, 2022-11)
The aeronautic industry is facing many challenges regarding the lifetime, weight and accuracy that aircraft skins must comply to meet stringent structural and aerodynamic requirements. Currently, mechanical milling of ...
Latest Developments to Manufacture Metal Matrix Composites and Functionally Graded Materials through AM: A State-of-the-Art Review
(MDPI, 2023-02-20)
Multi-material structure fabrication has the potential to address some critical challenges in today’s industrial paradigm. While conventional manufacturing processes cannot deliver multi-material structures in a single ...
Thermal Diffusivity Measurement of Laser‐ Deposited AISI H13 Tool Steel and Impact on Cooling Performance of Hot Stamping Tools
(MDPI, 2020-01-20)
Additive manufacturing is a technology that enables the repair and coating of high‐addedvalue
parts. In applications such as hot stamping, the thermal behavior of the material is essential
to ensure the proper operation ...
Study of the flexural behaviour and bonding strength of WC-Co metal matrix composite coatings produced by Laser Directed Energy Deposition
(Elsevier, 2023-06)
Surface coatings enable more durable and sustainable solutions to face the degradation of the functional surfaces of high-added-value components. Particularly, metal matrix composites (MMC) are known to mitigate friction ...
Analysis of the regimes in the scanner-based laser hardening process
(Elsevier, 2016-10-10)
Laser hardening is becoming a consolidated process in different industrial sectors such as the automotive industry or in the die and mold industry. The key to ensure the success in this process is to control the surface ...
