You3Dit and UL Tackle Corporate 3DPrinting Education on the West Coast


The Printrbot Simple Metal Plus (a 10″x10″x10″) machine next to the eNABLE Raptor 3D printable prosthetic – both ready and on display at today’s UL and You3Dit corporate education 3D printing workshop.

Today’s #3DPrinting workshop with Underwriters Laboratory (aka UL) will cover a broad span of the entire 3D printing industry followed by an up-close-and-personal exposure to Fused Filament Fabrication (FFF) style 3D printers.  Of the 7 major #3DPrinting technologies, FFF (very similar to FDM or Fused Deposition Modeling) are the most common amongst consumer 3D printers.

Students got up close and personal with 2x Printrbot Simple Metal Plus 3D printers.  They saw sample parts--both successful and unsuccessful prints--and were then shown how these parts are fabricated one layer at a time.  Photo credit goes to Melissa Albrecht at UL.

Onsite today are 4x of Printrbot‘s fleet of 3D printers:

  1. Printrbot Simple Metal Plus – their newest, 10″x10″x10″ machine
  2. Printrbot Simple Metal – their tried and true, “best value”, 6″x6″x6″ machine
  3. Printrbot Simple Makers Edition Original – kit version assembled by Chris from You3Dit

We will have the smaller machines printing smaller 3D printed parts from the fun RaverRing Kickstarter project and on the larger machines, a more meaningful project known as eNABLE – where 3D printer owners sync up with an organization that matches them with people who need prosthetics–not just lending a hand, but actually giving a hand.

We’ll show how these entry-level, yet powerful machines can literally transform people’s lives with the help of organizations like eNABLE who provide the design files free of charge and open source.

Is that RaverRing White and Gold or Blue and Black?


Our perception of color depends on how much we’ve danced our brains out the night before and interpreting the amount of RaverRing light that was flashed on the dance floor or the Burning Man playa.

When musical cues are accompanied by flashes of bright LED light coming from Kickstarter’s RaverRing Project, people often experience “the best night of [their] lives.”

The RaverRings in Question

A photograph from Instagram was posted the other day from user @You3Dit that asked, “What color are they?”  Some people see a nightlife dancing enhancement ring, other people see a device to help get the attention of inattentive drivers while exercising.  Some people see them doing both exceptionally well.

Let’s Take Some Averages

The Gold and White RaverRing on the left is bare skinned, “Bling Gold” PLA from with a white LED.  The RaverRing on the right is dark blue but covered with dark grey Performix Plasti-Dip.  If we take the two RaverRings and average the colors in a Dance Party, Rave, High-school Pep Rally or at an all-night event, we get the most epic party of our lives.

How Do We Interpret these RaverRings?

Our eyes, minds and bodies are only able to handle so much light and dancing awesomness under widely different partying environments.  This ability is called Rageability.  But the photograph doesn’t give many clues about the raging party that is going on in the background.  Are the party goers dancing on tables flashing their RaverRings to David Guetta?  Or Demi Lovato?  Or has the party left to rage in the streets?  Different people may presume one or more of these scenarios but the truth is, people who own RaverRings typically have a higher than average “Rageability”.

Whats the Answer?

Pre-order your RaverRings now before time runs out!  Even if you haven’t had your Rageability tested recently, RaverRings are like having training wheels on your new bicycle, or having the wind at your back while you bike up that miserably huge hill by your house…Don’t let your nightlife stay dark, light it up with a RaverRing today!
