Design with Use of 3D Printing Technology

"Abstract is the product of a diversified industrial 3D printing process, which is a contributing factor to its widespread acceptance. " Due to its availability and affordability, FDM is the most widely used and popular 3D printing method. Based on sample functional prototypes, usability of 3D printing technology FDM for the design of industrial objects is demonstrated in the paper. The 3D printed prototypes produced with the FDM process were found to be useful in establishing new ideas within the design processes carried out in KOMAG, according to the general conclusion.

Impact of increased UV curing time on the curing depth of photosensitive resins for 3D Printing

"Abstract Background 3D printing photosensitive resins are commonly used to produce patient-specific products in the fields of medicine and dentistry. The aim of this report was to determine the consequences of extending post-curing times for photosensitive resin printed parts. Hollow 60mm diameter spheres were printed using two commercially available vat-polymerisation 3DP systems. The spheres were divided along the centerline and radial measurements of the cured depth. Both transparent amber products cured to full depth at the 100% interval, according to the study, although none of the white or black opaque materials cured to full depth, even at 52% of the original recommendations. Obstructions Conclusions "Opacity has a significant effect on the degree of cure in photosensitive resins, and the use of opaque resins raises the likelihood of uncured resin remaining inside parts.

3D printing for surgical planning of canine oral and maxillofacial surgeries

"Abstract Background Paper "Abstract Background "Abstract Background" is a newspaper that publishes a summary of preoperative preparation for oral and maxillofacial surgery in veterinary patients. Presentation of a Dog 3D printed model Three 3D printed models are separated from computed tomography and cone beam CT for preoperative planning and intraoperative support for resection of maxillary osteosarcoma, mandibulectomy, and gap arthroplasty for temporomandibular joint ankylosis in dogs, ranging from computed tomography and cone beam CT to 3-D printed models fabricated by desktop vat polymerization. Conclusions We show multiple benefits and indications for 3D printing in surgical oral and maxillofacial surgery. Surgery planning is made simpler by allowing surgeons to personalize and enhance the surgical plan by investigating patient-specific anatomy and pathology. In addition, 3D printed models have the ability to enhance veterinary resident and student education, as well as pet owner education and reporting regarding their pets' health, treatment strategy, and intended outcomes.

3D PRINTING TECHNIQUE FOR PATIENT-SPECIFIC INSTRUMENTATION IN TOTAL KNEE ARTHROPLASTY

"The aim of the research was to assess the clinical and radiological results of knee arthroplasty using patient specific guides produced using physical prototypes and 3D printing that are used for positioning resection blocks. " The authors analyzed the clinical results of 4 patients during the period from 2015 to 2016 when total knee arthroplasty for posttraumatic gonarthrosis of the III-IV stage, using patient specific resection blocks positioning. All patients complained of apparent mobility in the knee joint early on, but most patients complained of severe limitations of mobility in the knee joint. U201c: U201d 201. 0 (u201d): U201d 67. 0 points, 51. 0. 0u00b114. 0, for u201cdaily physical activity (u201cdaily physical fitness), U201d u201d, 74. 5, u00b114. 0, for u201d. com u201d and stiffness-u201d, u201d u201d, 85. 2 In all patients, the authors observed a significant improvement in joint function and a pain syndrome reduction. When the use of intramedullary guides is impractical or prevents proper positioning of the femoral bone, aspirant proliferation of the femoral joint; significant mobility limitations in the knee joint; or use of a standard set of instruments poses significant technological challenges, according to authors' comments.

Regulatory Concerns about Medical Device Manufacturing Using 3D Printing: Current State of the Issue

"The authors obtained facts and guidance on laws and regulations governing 3D printing of medical devices in Russia and elsewhere in this collection. 3D printing is one of the most promising avenues for the creation of new therapies, but iiiunediate establishes concrete criteria for its regulatory approval is required. The problem of the quality of 3D models, material standardization, and manufacturing processes using 3D printing methods remains unresolved.

In situ 3D printing of liquid metal-hydrogel hybrid for multifunctional soft bioelectronics and devices

After one-step cross-link, single or multilayer LM patterns are 3D-printed and encapsulated in ionic hydrogel, with the exception of a simple in-situ 3D printing process being developed to produce liquid metal -hydrogel hybrid structures. " The easy and quick in-situ 3D printing process created a universal yet multifunctional platform for the wide variety of hydrogel bioelectronics and devices.

USE OF 3D PRINTING MATERIALS FOR THE MANUFACTURE OF UNMANNED AERIAL VEHICLES

"Today, the manufacturing of UAVs is expanding rapidly, becoming more advanced; production volumes are increasing, accuracy, and quality of manufacturing parts are improving with reduced costs. " On a 3D printer, several parts of UAVs can be printed. According to results, AT's use in the manufacture of UAVs at the current stage will increase the aerodynamic characteristics of drones, minimize total weight, and allow for the collection and repair of UAVs in the field. The introduction of AT will lead to a change in existing print technology design, the introduction of new ones in the design of modern 3D printers, and the emergence of new, related to 3D printing technologies. "Why study of the factors that influence the printed material of UAVs is a highly useful task that demands further study" is why thatu2019s.

A Novel Method to Adjust Saphenous Vein Graft Lengths Using 3D Printing Models

"Background: In surgical coronary revascularization, it is often difficult to obtain a sufficient length of saphenous vein grafts. " Methods: Sixteen patients who underwent bypass surgery without the use of vein grafts were evaluated. Patients' measurements of graft lengths were obtained from postoperative CT scan photographs and both 3D print models manually with plastic tubes and via 3D printed digital images of Mimics software during segmentation. Conclusion: 3D printing models and their applications can be used to determine the optimal saphenous graft length and the anastomosis site in order to reduce operation time," said David.

Binder Jet 3D Printing of Magnesium Oxychloride Cement-Based Concrete: A Framework to Design the Rate of Voxel

"The present work explores the powder bed binder jet 3D printing as an additive manufacturing process for cement-based products in the building industry. " Features are created as a result of the interaction between the droplets of the liquid binding agent and the layered powder bed. The planned cross-section is based on a voxels and single-lines from the coalesce of successive droplets and adjacent lines as a result of a given feed rate form. Using a factorial design of experimentation, statistical models have been created to investigate the effects of printing parameters on a single printed line's resultant dimension. The 3D printer's hardware, the powder blend's physical characteristics, and binder are the first constraints for designing voxels. Typical porosities from crater channels during the printing process are identified as higher residual porosity from Cubic samples printed with higher pressure level. ".
