Extruder‐based 3D printing of eco‐friendly polymers

Polymer International, EarlyView.
Eco‐friendly polymers, such as biodegradable and recycled materials, offer significant potential for the production of high‐quality 3D‐printed components, provided that their properties and characteristics meet the requirements of extruder‐based 3D printing.

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.

Impact of Packaging and Recycling Systems on Material Recirculation: A Stage‐Decomposition Model

Packaging Technology and Science, EarlyView.
A system‐level view emerges from decomposing recycling into four stages (participation, collection, sorting and process yield), diagnosing constraints and targeting interventions. Cumulative equivalent uses (CEUs) quantify long‐term retention, revealing marginal improvements at high baselines generate disproportionately larger gains than low‐baseline ...

Assessment of Different Technologies in the Fabrication of 3D Printed Tooth Models for Dental Education

European Journal of Dental Education, EarlyView.
ABSTRACT Background 3D printing has emerged as a practical method for fabricating customisable, accurate and affordable dental training models. Numerous 3D printing technologies exist, though there is no standardised comparison to inform their implementation in dental education.

Dental Arch Expansion With In‐House Clear Aligners: An Exploratory Prospective Clinical Study on Torque, Vertical Control and Attachment Configuration

Orthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objective To evaluate the short‐term efficacy of transverse dental arch expansion with in‐house aligners (IHA) by comparing planned and achieved buccolingual movements, and secondarily to explore torque expression, vertical control and the influence of attachment design/position using a contralateral within‐subject approach.

FieldDino: Rapid In‐Field Stomatal Anatomy and Physiology Phenotyping

Plant, Cell &Environment, EarlyView.
ABSTRACT Stomatal anatomy and physiology define CO2 availability for photosynthesis and regulate plant water use. Despite being key drivers of yield and dynamic responsiveness to abiotic stresses, conventional measurement techniques of stomatal traits are laborious and slow, limiting adoption in plant breeding.

Some thermodynamic and kinetic properties of the system PETG‐CO₂, and morphological characteristics of the CO₂‐blown PETG foams

Polymer Engineering & Science, 1999
AbstractThe solubility of CO2 in PETG, a glycol‐modified PET, was measured at different temperatures and over a broad pressure range, and diffusion coefficients were derived at the corresponding conditions. The solubility of CO2 is quits high. For example, almost 15 wt% CO2 can be dissolved in PETG at 35°C and 6.0 MPa. Consequently, CO2 is good blowing

Influence of Annealing Temperature on the Thermomechanical Properties and Dimensional Stability of FFF‐Printed PET‐CF

Journal of Applied Polymer Science, Volume 143, Issue 38, October 10, 2026.
Following extrusion at 265°C, components underwent a 45‐min annealing process at temperatures from 145°C to 225°C. The results show that increasing the annealing temperature elevates the onset of thermal softening, significantly enhancing thermal reliability.
