Characterization of welding notch designs and the impact on mechanical properties of 3D-printed PLA parts joined by a 3D pen

Michalak, Martin; Boca, Marius-Andrei; Sover, Alexandru (Editorial Universitat Politècnica de València, 2023-01-10)

[EN] 3D-printing has been established as a fast and low-cost technology to produce prototypes in small numbers. However, depending on the geometry of a part the print time still can be reduced by splitting the part in two ...
Design and testing of multi-material flexure hinges for Fused Filament Fabrication

Ermolai, Vasile; Sover, Alexandru; Nagît, Gheorghe (Editorial Universitat Politècnica de València, 2023-01-10)

[EN] Flexure hinges are non-assemble flexible joints that allow the relative rotation of two adjacent rigid parts through bending. Traditionally thermoplastic material hinges are made through injection moulding. 3D printing ...
Development of recyclable jointless plastic grippers for use in the medical technology sector

Sover, Alexandru; Zink, Markus; Boca, Marius-Andrei; Schönbucher, Thomas (Editorial Universitat Politècnica de València, 2023-01-10)

[EN] Medical grippers can be used for various purposes. They are a standard instrument in medical technology and are widely used every day for multiple applications. Jointless grippers, which, due to their geometry and ...
Influence of contact interface design over the bond for-mation of 3D printed parts

Ermolai, Vasile; Sover, Alexandru; Nagîț, Gheorghe (Editorial Universitat Politècnica de València, 2024-03-12)

[EN] Fused Filament Fabrication (FFF) is an additive manufacturing technology that uses molten thermoplastic materials forced through a nozzle to build parts layer-wise and enables the manufacturing single and multiple ...
Influence of cooling conditions during 3D printing on the switching temperature of a TPU with SME

Lang, Anette; Boca, Marius-Andrei; Sover, Alexandru (Editorial Universitat Politècnica de València, 2023-01-10)

[EN] Shape memory polymers (SMP) are materials with a special structure, designed to react to a certain stimulus. Using such SMPs with 3D printing technology opens up further fields of application thus providing for the ...
Influence of storage conditions of PVC rooftop sheets on the hot air welding process

Michalak, Martin; Sover, Alexandru (Editorial Universitat Politècnica de València, 2024-03-12)

[EN] One of the common welding methods for polymer rooftop sheets is the overlap welding by hot air. For this method two rooftop sheets are put over each other with a certain overlapping part and then a hot air fan, followed ...
Recycling of Laboratory Plastic Waste – a Feasibility Study on Cell Culture Flasks

Sover, Alexandru; Ermster, Kathrin; Riess, Alisha; Martin, Annette (Editorial Universitat Politècnica de València, 2024-03-12)

[EN] Laboratories contribute considerably to the global production of plastic waste. It was estimated that labs involved in biological, medical, and agricultural research produce around 5.5 million tonnes of plastic waste ...
Short foray into the stages of conversion from 2.5D to volumetric printing

Boca, Marius-Andrei; Sover, Alexandru; Slătineanu, Launrențiu (Editorial Universitat Politècnica de València, 2024-03-12)

[EN] Additive manufacturing gained popularity in the 2000s and is now considered a new or emerging technology of the 21st century. However, the origin of the process is much older and has existed for several decades, more ...
The impact of the G-code flavour selection in FFF

Eva, Silviu-Cristian; Sover, Alexandru; Ermolai, Vasile (Editorial Universitat Politècnica de València, 2023-01-10)
