Abstract This paper introduces the concept of continuous chaotic printing, i.e. use flows for deterministic and extrusion fibers with internal multilayered micro- or nanostructures. Two free-flowing materials are coextruded through a printhead containing miniaturized Kenics static mixer (KSM) composed multiple helicoidal elements. produces fiber well-defined multilayer microarchitecture at high-throughput (>1.0 m min −1 ). The number mixing elements diameter determine thickness lamellae,...
A machine tool for the automatic fabrication of biocompatible scaffolds with embedded nanofibers mats was built. In this novel process, produced by Fused Deposition Modeling (FDM) were polycaprolactone (PCL) in between object layers. The mat obtained far field electrospinning and its pore size controlled process. An additional micromachining used to drill create microchannels hybrid geometry as required. This will further be combination cell cultures study stem adhesion, proliferation...
The combination of different materials and capabilities to manufacture at several scales open new possibilities in scaffold design for bone regeneration. This work is focused on bimodal scaffolds that combine polylactic acid (PLA) melt extruded strands with polycaprolactone (PCL) electrospun fibers. type offers better mechanical properties, compared the use PCL strands, provides potential a means controlled drug and/or growth factor delivery through technologies fused deposition modeling...
Multi-material and multilayered micro- nanostructures are prominently featured in nature engineering recognized by their remarkable properties. Unfortunately, the fabrication of nanostructured materials through conventional processes is challenging costly. Herein, we introduce a high-throughput, continuous, versatile strategy for polymer fibers with complex nanostructures. Chaotic electrospinning (ChE) based on coupling continuous chaotic printing (CCP) electrospinning, which produces an...
Abstract Cancer continues to be a leading cause of mortality in modern societies; therefore, improved and more reliable vitro cancer models are needed expedite fundamental research anti-cancer drug development. Here, we describe the use miniaturized continuous stirred tank reactor (mCSTR) first fabricate mature spheroids (i.e. derived from MCF7 cells, DU145 mix cells fibroblasts), then conduct assays under perfusion. This 3 ml mCSTR features an off-center agitation system that enables...
The use of vascular grafts is indicated in a wide range medical treatments. While autologous tissue the graft choice most surgical bypass procedures, next best option synthetic grafts. significant advances have been reported electrospinning for both at vitro and vivo level, work limited to straight, tubular shapes with uniform diameters. In order generate resorbable scaffolds curving bifurcated non-uniform diameters, this study proposes combination directed electrical field dynamic...
Coconut waste is a by-product of commercial, industrial or agricultural activities, so that alternative uses for such are currently being sought.In Mexico, 66,203.22tons coconut were generated during the 2016 production cycle.Mexico City's Central Market produces 108,000 kg/year fiber waste, which sent directly to final disposal without submitted any type treatment.Therefore, general objective this work was find way use cellulose nanofibrils obtained from residues elaborate biomaterials may...
In this paper, we characterized an assortment of photopolymers and stereolithography processes to produce 3D-printed molds polydimethylsiloxane (PDMS) castings micromixing devices. Once materials were screened, the validation soft tooling approach in microfluidic devices was carried out through a case study.

The use of hybrid manufacturing to produce bimodal scaffolds has represented a great advancement in tissue engineering. These provide favorable environment which cells can adhere and new tissue. However, there are several areas opportunity manufacture structures that enough strength rigidity, while also improving chemical integrity. As an the process scaffolds, cooling system was introduced fused deposition modeling (FDM) machine vary temperature on printing bed. Two groups polylactic acid...

Interdigitated capacitive electrode structures have been used to monitor or actuate over organic and electrochemical media in efforts characterize biochemical properties. This article describes a method perform pre-characterization of interdigitated using two methods: hybrid voltage divider (HVD) vector network analyzer (VNA). Both methodologies develop some tests under different conditions: free air bi-distilled water media. Also, the HVD methodology is for other phosphate buffer with...
