Jan 15, 2025 · In this study, we designed and developed a warm isostatic pressing (WIP) to fabricate a hybrid structure using additive-manufactured polyetheretherketone (PEEK) and Ti-6Al-4V (Ti64) with an octet-truss lattice structure (OT).

mplementing a thermo-mechanical topology optimization method. This method utilizes porosity-dependent heat conduction, convection to dissipate in-ternal heat generation. while maintaining...

Aug 6, 2017 · Lattice cooling (LC) is a novel approach to improve the thermal and mechanical performance of an injection mold, thus challenging the traditional conformal cooling approach. By using current...

The proposed approach seeks to minimize the injection mold mass while satisfying constraints on mechanical and thermal performance. The optimal injection molds are characterized by a quasi-periodic distribution of lattice unit cells of variable relative density.

Using selective laser melting (SLM) is possible to manufacture molds with cellular internal structures with different porosity degree. Furthermore, internal geometry design can be improved as a function of the desired structural and thermal stress solicitations.

Thus, the design of the lattice structure is presented together with the development of a robust framework to automatically generate the lattice structure from truss-based unit cells. A homogenization model is then validated using a material …

Long-fiber reinforced thermoplas-tics (LFT) are usually prepared by an injection process using LFT pellets which are individual granulates with length of 10–25 mm sliced from continuous fibers with a polymer matrix surrounding them by pultrusion process.
