SAMG Proposal on Feasibility Study for 3D Printer Project - Peter Gheude 9-9-2017 SAMG proposal on feasibility study for 3D printer project - Peter Gheude 9-9-2017 What is RAMPS ? The Replication Rapid-Prototyper Project (RepRap) is an open source hobbyist “do it yourself” low cost 3D printer project. RepRap Arduino Mega Pololu Shield, or RAMPS for short is a motor controller shield for the Arduino Mega2560.

Is it worthwhile that members participate in a feasibility study to build an FDM 3d Printer? The committee and volunteers could shop around to determine if the components can be bulk purchased at an affordable price? A fun project and in keeping with the groups goals.

In this study, a systematic review was conducted of the liter­ Additive manufacturing ature regarding the use of AM in ergonomic-product design, and methodological aspects of the studies were Ergonomics analyzed. A literature search was performed using the keywords “3D print*,” “additive manufacturing,” “ergo­ Human factors nomic*” and “human factors”. Included were studies reporting the use of AM specificallyin ergonomic design of products/prototypes including the detailing of an ergonomic testing methodology used for evaluation. Forty studies were identified pertaining to the fields of medicine, assistive technology, wearable technology, hand tools, testing devices and others. The most commonly used technology was fused deposition modeling with polylactic acid, but the overall preferred material was acrylonitrile butadiene styrene. Various combinations of objective/subjective and qualitative/quantitative product evaluation methods were used. Based on the findings, recommendations were developed to facilitate the choice of most suitable AM technologies and materials for specific applications in ergonomics. 1.

  • Opportunities and Scope of Desktop 3D Printers in India
    International Journal of Engineering and Advanced Technology (IJEAT) ISSN: 2249 – 8958, Volume-8 Issue-6, August 2019 Opportunities and Scope of Desktop 3D Printers in India Vishwa Poswal, Ram Dayal, Ravi Kant Gupta in many fields of engineering and industry such as aircraft, Abstract. AM is an advanced manufacturing technology used dental restorations, medical implants, automotive products, for fabricating parts in layers, from a CAD file. Various methods construction and prototyping [3]. With the reduced cost and and materials have been developed to cater to its expanding size of 3D printers in the recent-past, the category of personal applications. AM has seen tremendous growth in the recent past. While growth in the technical aspect is essential for the or desktop 3D printers was introduced. Personal or low-cost development of new techniques, growth in the economic aspect desktop 3D printers are those AM machines which have a unit provides the need of innovation. With its ever-increasing cost of less than $5,000 [4]. Personal 3D printers are chiefly industrial and personal applications, the 3D printing technology based on FDM, as complex geometrical parts can be produced has experienced advancements in both the aspects. Yet its full safely in an office-friendly environment using thermoplastics potential has not been harnessed in developing countries. In this [5]. Hence, the range of its applications were expanded to work, it is proposed to optimize the existing desktop 3D printers for developing countries. A market survey was conducted to homes, schools, offices, libraries and laboratories. recognise the lagging areas and the design modifications were When compared to industrial 3D printers, the market made accordingly to produce a compact, efficient and segment of personal 3D printers is recent, yet, it has achieved cost-effective personal 3D printer for the respective needs and an average annual growth rate of about 170% from 2008 to applications in developing countries.

The development of a process that produces ceramic parts with 3D printing can also enhance the reliability and reduce the cost of manufacturing small-scale electronic components. The Direct Ink Writing (DIW) process was selected for its relatively low cost of entry, ease of use, and for its use of ceramic pastes and slurries similar to those used traditionally in tape casting and slip casting ceramic manufacturing methods. To execute the DIW process, I am using a modified off-the-shelf consumer 3D printer. Understanding how the controllable parameters of the DIW process and hardware can affect the quality, precision, speed, and capabilities when printing a BaTiO3 based slurry is the first step towards optimizing the DIW process for prototyping and mass commercial applications.

Despite that, the use of bio-based composites for improved mechanical properties and biodegradation is still not fully explored. This limits the universal expansion of AM-fabricated products due to the incompatibility of the products made from petroleum-derived resources. The development of naturally-derived polymers for AM materials is promising with the increasing number of studies in recent years owing to their biodegradation and biocompatibility. Cellulose is the most abundant biopolymer that possesses many favorable properties to be incorporated into AM materials, which have been continuously focused on in recent years. This critical review discusses the development of AM technologies and materials, cellulose-based polymers, cellulose-based three-dimensional (3D) printing filaments, liquid deposition modeling of cellulose, and four-dimensional (4D) printing of cellulose-based materials.

But now it is becoming a key part of the manufacturing mix alongside injection molding and computer numerical control machining. The use of polymers – particularly plastics – in 3D printing still exceeds metals, but the gap is narrowing, and metals could outstrip polymers from 2021. Healthcare is a strong adopter, with applications from medical training to the operating table. Great Ormond Street Hospital’s use of 3D printed models for an operation to separate twins joined at the head has increased awareness.

WPI routinely publishes these reports on its website without editorial or peer review. For more information about the projects program at WPI, please see http://www.wpi.edu/academics/ugradstudies/project-learning.html Copyright Notice The work presented in this document is copyrighted by students Nicholas Colucci, Noah Donald, Alexander Johnson, Andrew Kacherski, Dante Mauriello, and Owen Smallcomb and Professors Pradeep Radhakrishnan and Joe Stabile (Department of Mechanical Engineering, Worcester Polytechnic Institute). 1 Abstract A 3D printer is a powerful machine that allows for rapid realization of designs. Reducing the downtime between print cycles is essential for use in mass production or when multiple users are using the same printer. Presently, an operator manually removes the print from the machine and starts a new print. This project is an improved system from a previous Major Qualifying Project (MQP) to automate this process and eliminate downtime. The system consists of modular sub-systems, making it compatible with any i3 style printer. In the case of a printer with a removable bed, our system removes parts by lifting the bed from the printer and feeding it through a curved track that causes the bed to bend.
