Analysis, Validation and Optimization of the Multi-Stage Sequential Wiredrawing Process of EN AW-1370 Aluminium
(MDPI, 2019)
For the wiredrawing of aluminium, the initial wire rod is obtained by continuous inverted casting. The raw geometry is industrially processed in a linear multi-step wiredrawing sequence to obtain a wire that is commonly ...
Decision Tree Methods for Predicting Surface Roughness in Fused Deposition Modeling Parts
(MDPI, 2019)
3D printing using fused deposition modeling (FDM) includes a multitude of control parameters. It is difficult to predict a priori what surface finish will be achieved when certain values are set for these parameters. The ...
Stripping of PFA Fluoropolymer Coatings Using a Nd:YAG Laser (Q-Switch) and an Yb Fiber Laser (CW)
(MDPI, 2019)
Fluoropolymers such as PFA are used as coatings for the protection of metal substrates due to their high chemical inertia and non-stick properties. These are “wear and tear” coatings and they degrade, at which point they ...
Superhydrophobic Cerium-Based Coatings on Al-Mg Alloys and Aluminized Steel
(MDPI, 2019)
Aluminum-magnesium (Al-Mg) alloy and aluminum-coated steel (aluminized steel) are typically used for the manufacturing of baking trays and molds. For these applications, these materials must be modified to develop release ...
Use of 3D Printing in Model Manufacturing for Minor Surgery Training of General Practitioners in Primary Care
(MDPI, 2019)
In order to increase the efficiency of the Spanish health system, minor surgery programs are currently carried out in primary care centers. This organizational change has led to the need to train many general practitioners ...
Study on the Main Influencing Factors in the Removal Process of Non-Stick Fluoropolymer Coatings Using Nd:YAG Laser
(MDPI, 2019)
The coatings with fluoropolymer resins rich in fluorinated ethylene propylene (FEP) and polytetrafluoroethylene (PTFE) are applied as anti-adherent coatings on aluminum–magnesium substrates for use in food containers. In ...
Water-Repellent Fluoropolymer-Based Coatings
(MDPI, 2019)
Fluoropolymer-based coatings are widely used for release applications. However, these hydrophobic surfaces do not reveal a significantly low adhesion. Water repellency incorporated to fluoropolymer coatings might enhance ...
Improvement of Surface Roughness and Hydrophobicity in PETG Parts Manufactured via Fused Deposition Modeling (FDM): An Application in 3D Printed Self–Cleaning Parts
(MDPI, 2019)
The fused deposition modeling (FDM) technique is used today by companies engaged in
the fabrication of tra c signs for the manufacture of light-emitting diode LED spotlights. In this
sector, the surface properties of the ...
