Biopolymers are utilized extensively in the medical field. The production of biodegradable bone screws for implants utilizing biopolymer materials is one advances developments. Polylactic acid (PLA) a frequently employed medicinal applications. Using 3D printing, this research was done to create screw derived from PLA. printing process chosen reduce cost and duration repair. A nozzle temperature 210oC bed 60oC PLA screws. torque test, fracture analysis, density biodegradation test were...
Green mussel and crab shells are natural sources of CaCO3, which is widely used as a bioceramic for biomedical applications, although they commonly disposed in landfills. The improper disposal green can cause environmental pollution, reducing the quality life community. Many studies have reported preparation CaCO3 from mussels shells. However, there limited comparing characteristics, including crystal phase obtained, weight percentage (%) crystal, size, system, elemental composition shells,...
Abstract Biocomposite is a material that have potential to heal injured bones and teeth due their biocompatible, non-toxic, non-inflammation, bioactive properties which can prevent infections occurs frequently during surgical processes. Biocomposites made of PLA, PCL, HA from bovine bone as substitute for metal materials in medical applications been widely studied. However, there are limited studies on the biocomposites green mussel shells. Therefore, this study aims produce Polylactic Acid...
Chitosan has been broadly utilized in bone scaffold production because of its antibacterial qualities, low toxicity, biodegradability, biocompatibility, and ability to aid regeneration processes wound healing. In this work, chitosan was produced from crab shell waste through demineralization, deproteination, deacetylation, utilizing HCl 1:7 (v/v), NaOH 3%, 1:10 (v/w), 50%. The aim study is examine the deacetylation temperature’s impact towards crystallinity index, chemical bond, degree...
The invention of three-dimensional (3D) printing has transformed the medical field, offering sophisticated and accurate options for surgery planning, education, individualized therapy. Although 3D is widely used, little known about how parameters process affect properties composites reinforced with hydroxyapatite (HA) that been derived from crab shells. present study investigates influence nozzle temperature in fused deposition modeling (FDM) on physical, mechanical degrading PLA/PCL/HA...
Recently, there has been an increase in the number of studies conducted on process developing hydroxyapatite (HA) to use biocomposites. HA can be derived from natural sources such as bovine bone. The usage obtained green mussel shells biocomposites this study will explored. research goal is investigate composition effect biomaterials polycaprolactone (PCL), polylactic acid (PLA), well with a chemical blending method mechanical properties and degradation rate. First, 80 mL chloroform solution...
Abstract Additive manufacturing (AM) is a sustainable approach because it can lower emissions and have negative impact on the environment. 3D-printed interference screws from poly-lactic acid, eco-friendly filament, by fused deposition modelling (FDM), were fabricated with different process parameters. The most popular technique for reconstructing anterior cruciate ligament screw fixation. This study considered role of AM sustainability paradigm in terms material input FDM product...
Fractures and ligament injuries often require bone fixation, commonly through Open Reduction Internal Fixation (ORIF) with compression plates screws. Additive manufacturing (AM) techniques are considered sustainable due to their potential reduce emissions have a minimal adverse impact on the environment. Currently, there is extensive research into producing biocomposite filaments, though remains limited exploration of preheat temperature filament properties. This explores effects varying...
This study explores the production of interference screws using 3D-printed PLA/PCL/HA biocomposite filaments, focusing on effects nozzle temperature and printing speed screw quality. Experiments were conducted with temperatures 205°C, 210°C, 215°C, speeds 20 mm/s, 40 60 mm/s. Density, torque, fracture analysis, biodegradability tests used to evaluate screws. Results showed that higher print weakened layer bonds, increasing pores reducing mechanical strength. The optimal setting was 205°C...
