PLA/GNP filaments containing 0–1.6 wt% graphene are produced by melt compounding and fabricated into flexural specimens using FDM. Their mechanical response and fracture morphology are evaluated through ASTM D790 three‐point bending tests and SEM. Increasing graphene loading promotes agglomeration and interlayer defects, reducing strength, stiffness ...

Analysis of extrusion process parameters in PLA filament production for FFF technology [PDF]
Additive technologies are becoming a common part of not only prototype production, but also piece or small series production. However, the choice of technology and material plays a key role in the applicability of the manufactured parts.

A bio‐based, photocurable vitrimer system is developed for sustainable digital light processing (DLP) 4D printing. The material exhibits tunable thermomechanical properties, shapes memory and reconfigurability, and supports repair, reprocessing, and reprinting through dynamic covalent bond exchange, offering a recyclable and multifunctional platform ...

Parallel Vectors Extraction using Bézier Clipping
Abstract In this paper, we propose a novel local feature extraction algorithm for the parallel vectors (PV) operator. Our method is based on Bézier clipping, which is a bracketing‐based root finding method that is commonly‐used in computer‐aided geometric design.

Hydrologic changes driven by climate change are affecting aquatic biota in the Neotropical Region, with significant impacts on water striders. Species distribution models predict an increase in conservation importance for the northern Andes and coastal areas of eastern South America, while central South America shows a decline. The observed changes are

ABSTRACT Background/Aim This study aims to evaluate and compare the impact absorption capacities of thermoformed ethylene vinyl acetate (EVA) mouthguards and 3D‐printed polyolefin mouthguards used in sports dentistry applications. The objective is to determine whether 3D‐printed polyolefin mouthguards offer superior impact toughness compared to ...

Abstract Purpose To evaluate the marginal gap of two‐piece polyetheretherketone (PEEK) abutments fabricated with different methods, before and after thermal cycling, while also focusing on their pull‐off bond strength. Materials and Methods A two‐piece abutment was virtually designed after digitizing a titanium‐base (Ti‐base) abutment.
