Competition between University Students


Construction of high strength lightweight structures is one of the most common demands of the designers of engineering parts. Lower weight in mobile structures such as aircraft, ships, cars, and trains means higher mobility, lower fuel consumption and more cargo and passenger capacity. Lowering the weight is a serious concern even in the construction, sports, and fashion industry. In recent years, it has been possible to build up components of great complexity using 3d printers and the designers have merged optimization techniques with innovative and creative thinking to push the boundaries of these technologies further by the day.
The subject of this year’s additive manufacturing competition is the construction of lightweight components with high compressive strength. Porous 3D structures are used in various applications, such as body implants (bone structure), airplane fuselage or the body of space shuttles. To be considered for the contest, participants must build up polymeric cubes of 5 * 5 * 5 centimeters in one process and with no added part. The design must aim to minimize the weight while maximizing compressive strength. It is required that the piece weighs less than 80 g and that the Gcode file is sent along with the piece.
The following points need to be considered:
The specimen will be tested using a universal device under quasi-static load with 10 mm/min rate (as shown below).
The load value right before the failure or the value at 40 % deformation (equivalent to 2 cm) will be taken as the maximum compressive load. 
The maximum force (Newton) divided by the weight (g) is the evaluation criterion.
Samples must be sent to Iran Polymer and Petrochemical Institute at least one week before the conference and the announcement of the winners.

The second nation-wide event, which is to be held on December 14th-16th, 2018, aims to assess and aggregate existing capacities and establish a professional network between the players of this field. This event will be supervised and managed by the Advanced Materials Council (AMC) of Vice-Presidency of Science and Technology in three sections. Considering the growing trend of this technology in the country and the attention of the academic and research centers, this year's event will include a conference section. This is in addition to the previously announced exhibition and competition. Along with the event, keynote speeches will be delivered by lead scientists and technologists and the 3D printing contest, specially designed for teachers and students will be held at the same site.
