Abstract
A study of mechanical and optical properties of samples of transparent plastic Polyethylene terephthalate glycol (PETG) manufactured by additive technology Fused Filament Fabrication (FFF) was carried out. PETG plastic is used in medicine, particularly in dentistry due to its unique set of properties: strength, elasticity, resistance to aggressive environments, transparency. Preserving the complex of properties of PETG plastic, including transparency, during 3D-printing is an important technical task. In order to solve this task a set of studies of PETG laboratory samples was carried out. The optimum modes of 3D printing were determined to provide PETG samples with increased strength properties, preservation of elastic properties and optical transparency of the material. The increase in the optical transparency of the material is provided by an additional post-treatment of the printed samples surface with a chemical reagent. The influence of technological parameters of the post- treatment mode on the mechanical and optical properties of the printed samples has been investigated. The novelty of the work consists in a comprehensive study of the modes of manufacturing products from PETG by technology FFF with subsequent post-treatment, allowing to preserve the transparency of the polymeric material.
Highlights
The market for additive manufacturing materials is actively developing as additive manufacturing equipment is modernised to meet new consumer demands
The study of a set of properties of engineering thermoplastics for 3D printing using Fused Filament Fabrication (FFF) technology has attracted the attention of many researchers due to the need to achieve an optimal combination of material properties in printing, sufficient to meet the operational requirements for the finished product [3]
The research carried out and the analysis of the results allow the following general conclusions to be drawn: 1. Polyethylene terephthalate glycol (PETG) plastic is characterised by a unique combination of properties: mechanical, optical, structural
Summary
The market for additive manufacturing materials is actively developing as additive manufacturing equipment is modernised to meet new consumer demands. New materials as well as common thermoplastics with relatively wellstudied properties - ABS (acrylonitrile butadiene styrene) and PLA (polylactide), adapt to the most common technology of 3D printing - FDM (Fused Deposition Modelling) technology [1] or FFF (Fused Filament Fabrication) [2], which consists in layer-by-layer deposition of material in the form of thread (filament) according to the original program. Note that ABS and PLA thermoplastics, are widely used for 3D printing of objects without special requirements for material properties. The study of a set of properties of engineering thermoplastics for 3D printing using FFF technology has attracted the attention of many researchers due to the need to achieve an optimal combination of material properties in printing, sufficient to meet the operational requirements for the finished product [3].
