Abstract This article discusses the relevance of in situ quality assurance metal additive manufacturing for cost-efficient product qualification. It presents an approach monitoring laser powder bed fusion (LPBF) process using area-scan hyperspectral camera to predict surface roughness R z with help a convolutional neural network. These investigations were carried out during LPBF processing magn...

Different topical hemostatic materials are used to achieve effective hemostasis. High activity, biocompatibility, bioresorbability, and easy manipulation be expected in such a developed product. In the surgical world with these specific requirements, finding proper agent is very difficult. The study compared several of various construction properties, which were assessed for structural related ...

In this paper the dielectric properties of an implanted bioresorbable scaffold that is being used for the acceleration of the healing process of a fractured bone have been investigated. An implanted antenna system is presented for the monitoring of the resorption rate of the scaffold, which gives an indication on the healing process of the bone fracture. A simulation model of a three layer body...

Brushite (dicalcium phosphate dihydrate) and monetite (dicalcium phosphate anhydrous) are of considerable interest in bone augmentation owing to their metastable nature in physiological fluids. The anhydrous form of brushite, namely monetite, has a finer microstructure with higher surface area, strength and bioresorbability, which does not transform to the poorly resorbable hydroxyapatite, thus...

Bacterial infections after implant surgical procedures are a complication observed in many surgeries to treat bone injuries or diseases. Bacteria can attach the surface of producing biofilms, and if treatment with antibiotics does not work, further surgery is necessary remove infected implant. Among biomaterials for implants, bioceramics based on calcium phosphates (CaPs) such as β-TCP stand ou...

Polycaprolactone (PCL) is being developed as the material of scaffolds for tissue engineering [1]. PCL is considered having fair mechanical properties and characteristics of potentials for load bearing applications, including cardiovascular, dental, and musculoskeletal [1-4]. Yet, its implementation faces some issues, e.g. inadequate mechanical properties, bioresorbability, and hydrophilicity [...

Tissue engineering can be defined as an interdisciplinary field applying the principles of engineering and life sciences towards the development of biological substitutes that restore, maintain, or improve tissue function (Langer & Vacanti, 1993). To accomplish this aim, a balanced combination of cell culture growth with supporting biomaterials is required, as well as the introduction of bioact...
