Design and Implementation of Three-Dimensional Printable Optomechanical Components

Abstract

Fused filament fabrication 3D printing is a process by which three-dimensional objects are created by depositing layers of a material onto a hard, flat surface by a robot. It is often referred to as an “additive manufacturing” technique because material is added in successive layers to create an object. Because many scientific applications require parts that are expensive to purchase or manufacture, 3D printing custom parts for scientific instrumentation can save (shipping and/or manufacturing) time and money and requires only one compact, computer-controlled robot. Thus, 3D printable scientific parts and equipment can drive down the costs of scientific teaching and research. Here, we present a library of 3D printable optomechanical components that are compatible with commercial optomechanical parts. These components were tested for their functionality in home-built optical systems constructed entirely from 3D printed optomechanical components, and we demonstrate that optical systems built using 3D printable optomechanical components are comparable to their more expensive, commercially available counterparts, albeit not as durable as commercial parts. Thus, we conclude that our library of 28 3D printable optomechanical components is appropriate for use in scientific teaching laboratories.

Design and Implementation of Office Automation System Based on Internet of Things Technology

“…Gunderson and others said that cross platform refers to that programs can run across multiple platforms (microsoftwindows, applemacincash, Linux, etc.). The cross platform implementation of Java language actually provides a Java virtual machine (JVM) for each computer system [4]. Mohsen and others said that the Internet makes Java the most popular programming language at present, and Java has a far-reaching impact on the Internet [5].…”

Innovating in a bioimaging core through instrument development

“…32). Finally recent trends in 3D printing are paving the way to make optomechanics much more affordable 33,34 ) hence, for budget constrained projects, getting acquainted with the opportunities for additive manufacturing in microscopy is increasingly worth considering (for a review on 3D printables for microscopy, see Ref. 32).…”

The Fluorino: A Low-Cost, Arduino-Controlled Fluorometer

“…optical posts (DM-TR3), two adjustable lens mounts (DM-LH1), one cuvette and LED holder (JC-CLH1), and one breadboard holder (RB-BH1), and the six unique 3D printable optomechanical components are shown in Figure 1. Four of these components (DM-BA1, DM-PH2, DM-TR3, and DM-LH1) were presented in our previous article "Design and Implementation of Three-Dimensional Printable Optomechanical Components" 12 and two of these parts (JC-CLH1 and RB-BH1) are presented for the first time in this paper. The cuvette and LED holder (JC-CLH1) allows the LED used for excitation light to be placed closely to the cuvette holding the fluorescent sample, and the design of this component prevents any excitation light from reaching the photodetector (Figure 2A,B).…”
