After this, we use the Freecad software to design the channels where we will insert the plastic tubes through which the radiation source will deliver the treatment. We also use the Meshmixer software to make the final delimitation of the applicator edges as well as to find and correct any inconsistency.</p></div><div><h3>Results</h3><p>Moulds created by means of 3D printing allow us to combine the precise fit to the patient's surface of homemade solutions with the geometric accuracy between catheters of commercial products. This is clearly seen when treating small and irregular surfaces such as the ear pinna.</p></div><div><h3>Conclusion</h3><p>Manufacture of brachytherapy surface moulds with FDG technology is a good example of customized solutions in healthcare facilities supported by new European legistation. If we add to this the use of free open source software, we are facing an alternative to classics solutions used up to now in superficial brachytherapy.</p></div>","PeriodicalId":72210,"journal":{"name":"Annals of 3D printed medicine","volume":"12 ","pages":"Article 100124"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43346756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The initial flow emphasizes the broad categories of food printing materials and further, to stream the concept of personalized nutrition, a unique attention is focused on latest technological innovations in the 3D printed foodstuffs with different nutritional approaches viz., nutrition enhancement, minerals/vitamins fortification, functional ingredients enrichment and the development of alternative foods. In addition to current prominent scientific researches, literature stuffing adds a new flavor drawing attention on several industrially developed 3D food printed products that are reached and inline to the market. A prominent highlight was embarked on recent technical progress in the development of pharma foods, insect and plant based meat alternatives using 3D printing techniques. It is strongly believed that personalization and customization of 3D printed foods could be a future talk in compromising, unsatisfied nutritional problems and eradicating several chronical diseases in the pandemic era.</p></div>","PeriodicalId":72210,"journal":{"name":"Annals of 3D printed medicine","volume":"12 ","pages":"Article 100125"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48998632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An anti-staphylococcal herbal preparation, “Chlorophyllipt”, is produced mainly in a liquid form by the pharmaceutical industry in Ukraine, and it is composed of an ethanolic eucalypt extract (EE). Since staphylococcal infections have become a true challenge for the health care in all over the world, it would be relevant and justified to develop the aqueous gels of the present EE applicable for the 3D printing of the corresponding solid DDSs. The aim of the present study was to develop a novel polyethylene oxide (PEO) gel loaded with EE for a semi-solid extrusion (SSE) 3D printing and to print the corresponding oral solid DDSs with different sizes and shapes. For SSE 3D printing, we prepared and tested total ten (10) different aqueous PEO gel formulations loaded with EE. Prior to 3D printing, the physical appearance, homogeneity, injection force and viscosity of the gels were investigated. The EE-PEO gels were printed to lattice- and round-shaped solid DDSs with the head speed of 0.5 mm/s, and the weight (mass uniformity) and effective surface area of the printed systems were determined. The most feasible EE-PEO gel for SSE 3D printing comprised of 10 mg/ml of EE, 30 mg/ml of eumulgin and 20 mg/ml of ascorbic acid in a 20-% aqueous PEO gel. The key process parameters of the SSE 3D printing were identified and verified. The printing quality of EE-PEO DDSs were very good, thus showing compatibility of a plant extract and carrier polymer. Such 3D-printed antimicrobial DDSs can be used for example in the treatment of skin wounds and infections of the oral cavity.</p></div>","PeriodicalId":72210,"journal":{"name":"Annals of 3D printed medicine","volume":"12 ","pages":"Article 100123"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44366454","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
