A Review of the Control System of a 3D Printer

"The control system, which is a core feature of a three-dimensional printer, controls the orderly working procedure of all aspects of the printer and plays a key role in the three-dimensional printing's productivity and printing quality. " We examine the current 3D printer control system to ensure print quality and printing efficiency, with the goal of determining the latest technology in the 3D printer control system. The future research direction of a 3D printer control system is discussed in conclusion. The closed-loop control module and the 3D printer's opened-loop control system are analyzed by a large number of patents, and the 3D printer's development trend is discussed. Conclusion: The optimization of the 3D printer's control system is key to increasing printing quality and printing quality in the 3D printing process.

The feasibility of producing patient-specific acrylic cranioplasty implants with a low-cost 3D printer

A commonly used alternative to calcium bone cement is "Acrylic bone cement is a commonly used alternative. " However, manual shaping of the bone cement is laborious and may not result in a satisfactory implant in some situations. The purpose of this research was to determine the feasibility of moulding molds using a commercial low-cost 3D printer for the purpose of manufacturing patient-specific acrylic cranioplasty implants. METHODS Using data from a high-resolution brain CT scan of a patient with a calvarial defect posthemicraniectomy, a METHODS The resulting implant was fitted to the skull phantom, and the cranial index of symmetry was determined. RESULTS The skull phantom and mold were created using the 3D printer and were highly successful. Acrylic bone cement was applied to the mold by a simple and straightforward method.

Cranioplasty with a low-cost customized polymethylmethacrylate implant using a desktop 3D printer

"OBJECTIVE Cranioplasty implants should be widely available, low in cost, and customizable or easy to mold during surgery. " Polymethylmethacrylate is the most commonly used allogenic material for cranial reconstructions with long-term results. The authors describe their method and experience with a customized PMMA prosthesis that can be customized at any institution with open-source or low-cost apps and desktop 3D printers, respectively. METHODS The investigation of 22 consecutive patients undergoing CT-based, low-cost, customized PMMA cranioplasty over a 1-year period at a university teaching hospital was performed. RESULTS Indications for the primary craniectomy were traumatic brain injury, tumor resection, infection, and vascular. The median time between previous surgery and PMMA cranioplasty was 12 months.

General Function sets theory-based type synthesis of the collaborative 3D printer for planar and non-planar printing

"However, as far as the authors know, the exact design method of 3D printers' u2019 system has never been tested for non-planar printing. " One module acts as the build platform and the other as the print head attached moving platform. Hence, this paper explores the type synthesis first in order to determine topological characteristics of the collaborative 3D printer for planar and non-planar printing. Based on the planned pathsu2019 geometric characteristics and motion requirements of the 3D printer, the motion characteristics of the collaborative 3D printer, then, are determined. Lastly, this research paper introduces a line of rotary 3D printers that feature 2T1R, 2T2R, and 2T3R. This paper, in general, aimed at planar and non-planar printing, suggests a model for type synthesis of collaborative 3D printers to produce a more complete set of kinematic structures than the most commonly used three Degree of Freedom printers.

Redesign of Car Body by Reverse Engineering Technique using Steinbichler 3D Scanner and Projet 3D Printer

To get creative solutions, product design needs a concept design software like TRIZ. " In this paper, we've used an existing concept development and design software to establish a connection between the problem definitions, which have been identified as per customer needs, and the creation of the product physical parameters that meet the required specifications. Steinbichler 3D Scanner, Projet 3D printer, and associated Scanning and printing software are used in this Additive Manufacturing process, making the conversion and maintenance of a vehicle much faster in reduced time and cost.

Design of high precision multichannel biological 3D printer

A series of 6 channels biological 3D printing system is created that makes the six in one printing come true, "Based on the findings of the high-precision motion of the gantry structure and the needs of simultaneous and synergistic printing. " PMAC motion control subsystem, pneumatic control subsystem, and temperature control subsystem are all developed and configured based on the Visual C++ environment. It was also shown that the biological 3D printer and its control software can satisfy the demands of multichannel printing, simultaneous printing, and synergistic printing with submicron level motion accuracy, as well as improve printing quality.

Development of a customised 3D printer as a potential tool for direct printing of patient-specific facial prosthesis

"Material growth and characterisation enabled for the development and manufacture of a 3D printer capable of fabricating PDMS structures using a photo-initiator and a LED curing process. " A custom made 3D printer is used for in-situ concrete deposition of PDMS at room temperature, with in situ UV cross-linking to facilitate curing of the PDMS during the 3D printing process. This 3D printer has a great potential to be used as a fast and simple fabrication technique to produce facial and other prosthesis. ".

Comparison of axon extension: PTFE versus PLA formed by a 3D printer

"Abstract": "Abstract 3D printers mainly produce 3D objects by stacking thin layers of paper. The effects of the tools made using the fused deposition modeling 3D printer on nerve cells are uncertain. The results of polytetrafluoroethylene models and two other forms of polylactic acid models were found in this report, as well as two other forms of polylactic acid models, which were compared using the Campenot chamber. The difference between the axon extensions to the side compartments of each group was confirmed on day 7, after the establishment of the culture.
