Prototypes with a Twist

An inventor needed a customized auger for an unusual application. The problem was that it could not be produced using traditional  CNC machine methods or as an injection molded plastic part. So, a few hours spent with a product development expert at Sigma resulted in the complex blade geometry needed for the auger in a process that could be readily manufactured.

 With our Rapid Prototyping FDM machines we can take your design concepts and grow ABS plastic parts. Used as a quick, proof of concept development tool, parts can usually be created, manufactured and shipped in just two (2) days.

Sigma Design is ready to:
*Take your geometry and produce prototypes.
*Design new geometry and produce prototypes.
*Develop and manufacture prototype devices, specialty production equipment and controls with testing capabilities in-house.

Winning the Rat Race

The term ‘rat race’ has been described as a “seemingly pointless or endless pursuit”.   The work of today’s research scientist is hardly pointless but one aspect of the work, while not endless, was a tedious pursuit.  We are describing the work of researchers charged with the task of  observing and documenting the behavior of mice in lab settings. The job was to watch and score lengthy video recordings of the creature’s every move.  That was until Jessie Brodkin came up with an idea that he has described as “thinking inside the box”.  

Brodkin’s creation is The Behavioral Spectrometer (http://behavioralinstruments.com), a humane device that captures everything your mouse does without having to watch and score hours of video recordings.  Brodkin found SigmaDesign Company and its team of mechanical design engineers for the job.  Sigma designed, tested and now manufactures this ‘mouse house’, The Behavioral Spectrometer, right here in NJ.  The job required advanced engineering analysis and skills to incorporate LED lighting, vibrations sensors, and isolation dampers. It has the capability of using advanced video and vibration analysis to record the most detailed description of mouse behavior ever.      

Brodkin’s ‘made in NJ’ product has met with huge success in the research and pharmaceutical world. The Behavioral Spectrometer is used by Rutgers University’s Department of Neuroscience and Cell Biology, Pfizer, and other global R&D laboratories for the development of new treatments and drugs. The latest 4 systems were just shipped to a R&D laboratory in Austria. To read customer articles and references: http://behavioralinstruments.com/references

This is another success story showing Sigma Design Company’s ability to provide manufacturing engineering and product development services to people like you.Sigma Design is your single source engineering and manufacturing resource for new products and specialty machinery.

University and 3D Printing Industry Collaboration Featured on PBS

Lafayette College seniors Jake Hyatt and Max Bergelson visited Sigma’s 20,000 square-foot Technology Commercialization and New Product Manufacturing Center to film a project for their Political Economy course.

The college produced a public affairs program in partnership with PBS, which featured Sigma’s 3D rapid prototyping and manufacturing services.

According to Lafayette professor and executive producer Mark Crain, Lafayette College constantly wrestles with ways to bridge academics and real world developments. “The opportunity for Max and Jake to visit Sigma Design Company and see first hand how 3D printing is transforming business and society is an amazing opportunity.  They’ll learn even more as they produce our broadcast that illuminates this innovative, complex technology for PBS39 viewers,” he said.

The program was broadcast to approximately  2.6 million households in Pennsylvania and New Jersey. The program is available on the PBS39 YouTube site and the Lafayette College homepage.

Evidence of Standout Service

Model 4 corr

The figures Sigma design 3D printed placed on the model.

Low cost and fast turnaround is why The Evidence Store, a company providing legal photography, videos, and trail exhibit services, chose Sigma Design.

The company was asked to make a 1:28 scale model of an intersection in a case involving a large piece of construction equipment. One of the workers at the site was injured, and the model was going to be used in court to demonstrate the nature and geometry of the area.

Sigma was hired to make 16 3D human figures, with their initials on the base, to place and move around the model as part of the demonstration to the jury. The figures stood 2.57″ tall.

“From the minute we called Sigma we were treated by professional, friendly people,” said Stephen Appelbaum, President of The Evidence Store. “The case settled soon after the model was completed so it never saw the inside of a courtroom, but the out-of-state client was extremely pleased with the results and the fast service.”

Need a Prototype? Sigma Can Deliver

Sigma’s 3D Rapid Prototyping FDM Machine can take your design concept and create it in three days.

A human head model was a recent prototype that Sigma manufactured for Kelly Burke, a doctoral candidate at the Albert Einstein College of Medicine in the Bronx.

The research lab is investigating sensory processing in Autism and other developmental disorders using EEG and fMRI. For one of their studies they needed to create a custom, high-density EEG cap. In order to know where to put the electrodes in the cap, they needed to print a head model with the points on them, and contacted Sigma.  After receiving the Solidworks (STL) file, the model was ready to be shipped 3 days later.

“Sigma Design was an easy pick for this project not only because they gave the lowest quote, but more importantly they were the best at responding right away, and printed out exactly what we wanted in less time than they estimated,” Burke said. “Sigma answered all of our questions, took care of the paperwork, were careful about each detail, and the output head model is perfect! They made the process go so smoothly and accurately and I am already using the cap for our study.”
