On the Geometrical Accuracy of High Aspect Ratio Micromilled Pins [PDF]

open access: yes, 2017
Geometrical accuracy of micro-features in micromilling is strictly related with the choice of cutting parameters. Their correct selection is a challenging task in particular when the target feature geometry is a high aspect ratio feature with tight ...

High accuracy geometric Hermite interpolation [PDF]

open access: yesComputer Aided Geometric Design, 1987
In natürlicher Verallgemeinerung der Hermiteschen Standardinterpolation werden für parametrisierte ebene Kurven interpolierende kubische Splines p(i) bestimmt. Dabei sind die Knotenpunkte und in jedem Knotenpunkt Tangente und Krümmung vorgeschrieben. Die Komponenten von p(i) sind kubische Polynome auf den Parameterintervallen \((i,i+1)\).

Binder jetting additive manufacturing of hydroxyapatite powders: Effects of adhesives on geometrical accuracy and green compressive strength

open access: yesAdditive Manufacturing, 2020
Binder jetting additive manufacturing (AM) is a promising process to print hydroxyapatite (HA) powder into bone tissue implants. However, one challenge remaining is the poor reactivity between HA powder with standard water-based ink.
