Mexico is ranned first place among countries with plastic waste production; recycling mainly polyethylene terephthalate (PET), the recycling of other plastics is almost nil. Laboratory equipment are didactic elements in Manufacturing Engineering; It allows to develop professional competences required in this major, by integrating theoretical and experimental contents through laboratory practices. The problem of continuous use of 3D printers in lab practices is that, for each kilogram of polylactic acid (PLA) and acrylonitrile butadiene styrene (ABS), between 10% and 30% results in waste material. The university can hardly afford these supplies to the Manufacturing Laboratory because of the high cost of plasctic materials. That is why this project seeks to offer a technological proposal to give plastic waste a second life, as an outcome from laboratory 3D printers. This may decrease the environmental impact generated by the university. These wastes can be recycled, through a mechanical method, and used as material in the realization of laboratory practices that develop academic and professional skills of new manufacturing technologies.

University engineering departments are often challenged to maintain state of the art manufacturing facilities due to the rapid technological changes that are occurring in industry. Older or obsolete engineering laboratory equipment, manufacturing machines, and design tools are difficult to replace due to limited department budgets, space, and staff resources.At Capilano University, where a hands-on project-based one semester first year engineering design class is offered, the Engineering department has taken a novel approach to meet the above challenge.The Engineering Design students are required to design, build, and test original prototype electrical circuits, and mechanical structures as part of their design projects. Construction of these student-designed units requires a rapid turnaround manufacturing facility to meet the peak demands of the students, capabilities that smaller universities are often limited in their ability to provide.To meet this specific requirement, a community-based private rapid prototyping design and manufacturing facility, Zen Maker Labs, was approached, and a partnership agreement has been developed. The agreement consisted of cooperation between the university and the Zen Maker Lab to support up to 60 engineering design students. The students were provided with tools, safety training, and support for manufacturing. The facility has provided CAD design stations, several 3D printers, laser cutters, and numerically controlled milling machines to support manufacturing of student designs. Access to the manufacturing facility was initially provided on subscription basis, where students used the library to “sign-out” membership cards, and access the facility on a controlled,  supervised basis. The controlling of student numbers through the  university library provided a method for managing student access to themanufacturing facility over a period of 8-10 weeks. This arrangement for laboratory access has recently been expanded through a revised collaboration arrangement, and has provided engineering design students with handson experience with several manufacturing technologies and CAD engineering modelling and design tools.

This paper focuses on to convert photographs into embossed 3D models and then bring them to life using a 3D printer. A Lithophane is a 3-dimensional generation of a 2-dimensional image and 3D representation of a photo can be seen only when it is illuminated from behind. Turning images into 3D objects give us more feeling and literally adds a new dimension. The lithophane can be manufactured by the way of an automated additive manufacturing process, such as 3-D printing. lithophanes are a simple way to enhance your favourite photos. 3D printed photos also known as 3D Printed lithophanes, are an extremely unique and creative application. The process adopted in lithophane is FDM technology, in which different the materials like PLA (polylactic acid), ABS (acrylonitrile butadiene styrene), etc. By heating the filament material to its melting point and it is deposited layer by layer. Combination of many layers will give us a final 3D Printed model.

In order to expand the mechanical and physical capabilities of 3D-printed structures fabricated via commercially available 3D printers, nanocomposite and microcomposite filaments were produced via melt extrusion, 3D-printed and evaluated. The scope of this work is to fabricate physically and mechanically improved nanocomposites or microcomposites for direct commercial or industrial implementation while enriching the existing literature with the methodology applied. Zinc Oxide nanoparticles (ZnO nano) and Zinc Oxide micro-sized particles (ZnO micro) were dispersed, in various concentrations, in Acrylonitrile Butadiene Styrene (ABS) matrices and printable filament of ~1.75mm was extruded. The composite filaments were employed in a commercial 3D printer for tensile and flexion specimens’ production, according to international standards. Results showed a 14% increase in the tensile strength at 5% wt. concentration in both nanocomposite and microcomposite materials, when compared to pure ABS specimens. Furthermore, a 15.3% increase in the flexural strength was found in 0.5% wt. for ABS/ZnO nano, while an increase of 17% was found on 5% wt. ABS/ZnO micro. Comparing the two composites, it was found that the ABS/ZnO microcomposite structures had higher overall mechanical strength over ABS/ZnO nanostructures.
