Additive Manufacturing Methodology and System for Fabrication of Porous Structures with Functionally Graded Properties
Vlasea, Mihaela (University of Waterloo, 2014-02-26)The focus of this dissertation is on the development of an additive manufacturing system and methodology for fabricating structures with functionally graded porous internal properties and complex three-dimensional external ... -
Data related to architectural bone parameters and the relationship to Ti lattice design for powder bed fusion additive manufacturing
McGregor, Martine; Patel, Sagar; McLachlin, Stewart; Vlasea, Mihaela (Elsevier, 2021-12)The data included in this article provides additional supporting information on our publication (McGregor et al. [1]) on the review of the natural lattice architecture in human bone and its implication towards titanium ... -
Data related to the effect of specimen geometry and orientation on tensile properties of Ti-6Al-4V manufactured by electron beam powder bed fusion
Shanbhag, Gitanjali; Wheat, Evan; Moylan, Shawn; Vlasea, Mihaela (Elsevier, 2021-12)Additive manufacturing quality assessment often relies on tensile testing as the preferred methodology to qualify builds and materials. The data included in this article provides additional supporting information on our ... -
On the measurement of relative powder-bed compaction density in powder-bed additive manufacturing processes
Ali, Usman; Mahmoodkhani, Yahya; Imani Shahabad, Shahriar; Esmaeilizadeh, Reza; Liravi, Farzad; Sheydaeian, Esmat; Huang, Ke Yin; Marzbanrad, Ehsan; Vlasea, Mihaela; Toyserkani, Ehsan (Elsevier, 2018-10-05)Experimental studies in the literature have identified the powder-bed compaction density as an important parameter, governing the quality of additively manufactured parts. For example, in laser powder-bed fusion (LPBF), ... -
Powder bed binder jetting additive manufacturing of silicone structures
Liravi, Farzad; Vlasea, Mihaela (Elsevier, 2018-05-01)The feasibility of a hybrid additive manufacturing (AM) method combining material extrusion and powder bed binder jetting (PBBJ) techniques for fabrication of structures made of silicone (polysiloxane) is investigated in ... -
Sinter structure analysis of titanium structures fabricated via binder jetting additive manufacturing
Wheat, Evan; Vlasea, Mihaela; Hinebaugh, James; Metcalfe, Craig (Elsevier, 2018-10-15)To facilitate functional part production in metal binder jetting additive manufacturing, the relationship between materials, process and sintering needs to be understood. This work relates sintering theory with process ... -
Tailoring green and sintered density of pure iron parts using binder jetting additive manufacturing
Rishmawi, Issa; Salarian, Mehrnaz; Vlasea, Mihaela (Elsevier, 2018-12-01)Binder jetting additive manufacturing (BJAM) is a comparatively low-cost process that enables manufacturing of complex and customizable metal parts. This process is applied to low-cost water-atomized iron powder with the ...
