Selected Mechanical Properties of PETG 3-D Prints

Procedia Engineering, 2017
Abstract The 3D printing is a way of additive manufacturing that allows the creation of sophisticatedly shaped bodies at relatively low cost and in short time span. It is especially useful for rapid manufacturing, including engineering applications such as rapid prototyping. The commonly used fused deposition modelling (FDM) method dispenses filament

Additive Manufacturing of Cobalt Iron Oxide‐Based Photopolymer Resin Magnetoactive Polymer Composites Through Stereolithography

Macromolecular Materials and Engineering, Volume 311, Issue 3, March 2026.
In this study, novel resin/cobalt iron oxide magnetic actuation polymer composites (MAPCs) are synthesized and optimized for stereolithography (SLA)‐based 3D printing. Printing parameters are tuned for dimensional accuracy and print quality. Comprehensive physicochemical, mechanical, and magnetic characterization identifies the optimal formulation ...

Secrets within stems: The cryptic Apodanthes caseariae (Apodanthaceae), a rare neotropical holoendoparasite

PLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 385-400, March 2026.
Holoendoparasites are extremely rare plants that live entirely hidden inside their hosts, with only flowers and fruits visible. We studied Apodanthes caseariae, found in central and South America, parasitizing Casearia sylvestris. Little is known about its life cycle.
