This book presents the select proceedings of the International Conference on Structures, Materials and Construction (ICSMC 2021). It covers the recent developments and futuristic trends in the field of structural engineering and construction management, including new building materials and understanding their behavior. The topic covered also assess the current progress and state-of-the-art techniques in structural experimentation, smart materials, structures technology, principles of construction management, materials properties and characterization. The collection of papers included in this proceeding will contribute to scientific developments in the field of structural engineering and construction and will be a useful as reference material for the academicians, researchers and most importantly the student community pursuing research in the fields of structural engineering and construction technology.

¿Dieless forming¿ is the processing method without ¿die¿ as its name shows. Die less forming process using a 3D printer of carbon fibre reinforced plastic parts has developed to produce three-dimensional mechanical parts. Specimens for static and fatigue tests are manufactured by sandwiching the carbon fibres between upper and lower plastic plates made by 3D printing and by heating the sandwiched plates. The fatigue and static strengths are increased by thermal bonding of the plastic plates and carbon fibres. In addition, the strengths are heightened by including the carbon fibres in molten plastic. 3D printing is also called additive manufacturing. This term accurately describes how this technology works to create objects. "Additive" refers to the successive addition of thin layers between 16 to 180 microns or more to create an object. In fact, all 3D printing technologies are similar, as they construct an object layer by layer to create complex shapes. Dieless forming, an innovative sheet metal forming technology developed in Japan which enables a metal part to be formed directly from a CAD file in just a few minutes and with the utmost precision.
