PROPERTY EVALUATION METHOD OF CEMENTITIOUS MATERIAL FOR 3D PRINTING

Voxel-based fabrication through material property mapping: A design method for bitmap printing

Wepresent a bitmap printingmethod and digital workflow usingmulti-material high resolution Additive Manufacturing (AM). Material composition is defined based on voxel resolution and used to fabricate a design object with locally varying material stiffness, aiming to satisfy the design objective. In this workflowvoxel resolution is set by theprinter’s native resolution, eliminating theneed for s...

Metrology for 3D Printing: Assessing Methods for the Evaluation of 3D Printing Products

Instrumented cardiac microphysiological devices via multi-material 3D printing

Biomedical research has relied on animal studies and conventional cell cultures for decades. Recently, microphysiological systems (MPS), also known as organs-on-chips, that recapitulate the structure and function of native tissues in vitro, have emerged as a promising alternative. However, current MPS typically lack integrated sensors and their fabrication requires multi-step lithographic proce...

Multi-Material 3D Inkjet Printing - Conductive Paths in Polymer Parts

In this paper the results of a research project that deals with the conceptual design and evaluation of cross-company logistics models are presented. A simulation and evaluation model was designed that supports the development of new logistics concepts. Therefore models for the calculation of emissions, of costs and of logistic competitiveness, have to be created and combined. Based on the sust...

Method for Procedural 3D Printing Using a Python Library

When manufacturing or 3D-printing a product using a computer, a program that procedurally controls manufacturing machines or 3D printers is required. G-code is widely used for this purpose. G-code was developed for controlling subtractive manufacturing (cutting work), and designers have historically written programs in G-code, but, in recently developed environments, the designer describes a de...
