A Soft Robotic Fish With a Dielectric Elastomer Actuator Body and Negative Stiffness Spine

Advanced Robotics Research, EarlyView.
This work introduces a bio‐mimetic soft robotic fish driven by fiber‐reinforced dielectric elastomer actuators integrated as its body. By prestretching this active skin against a flexible spine, a negative stiffness system is created, enabling large‐amplitude bending.

EFFECT OF GEOMETRY AND SURFACE DISTRIBUTION OF HOLES ON SOUND AND LIGHT ABSORPTION PROPERTIES OF 3D-PRINTED PETG MATERIALS

MM Science Journal, 2023
Noise and lighting are significant factors that have an impact on our health, environment, production quality, etc. The purpose of this paper is to investigate sound and light absorption properties of 3D-printed polyethylene terephthalate glycol (PETG) material specimens that were manufactured with two types of holes, namely with circular and square ...

Development and Characterization of ZnO‐Filled and Maleic Anhydride‐Compatibilized PP/SEBS Blends for 3D‐Printing Filaments

Journal of Applied Polymer Science, EarlyView.
PP/SEBS/MA/ZnO filaments produced by bench‐top single‐screw extrusion show refined morphology, increased crystallinity, improved thermal robustness, and preliminary FFF printability, demonstrating a practical route for functional filament development. ABSTRACT Currently, single‐screw extrusion offers a versatile and accessible route to produce polymer ...

Circularity in 3D Printing with Poly(Ethylene Terephthalate Glycol): Copolymer Composition Dependent Degradation During Recycling

Macromolecular Materials and Engineering
Reduced environmental impact is commonly cited as a driver for additive manufacturing, but non‐circular end‐of‐life disposition of the printed materials reduces these advantages.

Organellar inheritance in the green lineage: insights from Ostreococcus tauri [PDF]

, 2013
Along the green lineage (Chlorophyta and Streptophyta), mitochondria and chloroplast are mainly uniparentally transmitted and their evolution is thus clonal. The mode of organellar inheritance in their ancestor is less certain.

Design and Additive Manufacturing of a Passive Ankle–Foot Orthosis Incorporating Material Characterization for Fiber-Reinforced PETG-CF15

Materials, 2023
The individualization of patient-specific ankle joint orthoses is becoming increasingly important and can be ideally realized by means of additive manufacturing. However, currently, there are no functional additively manufactured fiber-reinforced products that are used in the field of orthopedic treatment.

On‐deck pH measurement with integrated feedback control on a micro‐scale platform for monoclonal antibody low pH viral inactivation

Biotechnology Progress, EarlyView.
Integrating an automated, on‐deck pH measurement method with feedback control enables precise, real‐time pH adjustment during low pH viral inactivation on a micro‐scale platform. Abstract The increasing demand for efficient monoclonal antibody manufacturing has accelerated the adoption of high throughput process development (HTPD) platforms, which ...

Mechanical Properties of Additively Manufactured Polymeric Materials—PLA and PETG—For Biomechanical Applications

Polymers
The study presented herein concerns the mechanical properties of two common polymers for potential biomedical applications, PLA and PETG, processed through fused filament fabrication (FFF)—Material Extrusion (ME). For the uniaxial tension tests carried out, two printing orientations—XY (Horizontal, H) and YZ (Vertical, V)—were considered according to ...

The Effect of Nozzle Temperature, Infill Geometry, Layer Height and Fan Speed on Roughness Surface in PETG Filament

Journal of Mechanical Engineering Science and Technology, 2022
3D printing is a process of making three-dimensional solid objects from a digital file process created by laying down successive layers of material until the object is created. Many filaments can be used in 3D printing, one of which is PETG (PolyEthylene
