Here are the 7 companies we're excited to see next week at NPE 2018!

This is the first year Structur3D Printing will be exhibiting at NPE2018: The Plastics Show (http://www.npe.org/), from May 7-11 in Orlando, Florida.

We are certainly very excited to be demonstrating our soft materials 3D printing technology at the NPE show, but we are also extremely delighted to explore the showroom of nearly 2200 exhibiting businesses.

Earlier this week, we took some time to see which other companies would be exhibiting at NPE that would be interesting to check out.  We wanted to share a list of businesses influential in the area of new materials for 3D printing (as we see this as THE most important area for growth).  Make sure to add these companies to your NPE Agenda today!

Molecular Gastronomy and the art of Reaction-based 3D Printing

This post, written by Charles Mire, ran in 3DPrint.com last year. See original article here.

Eating and enjoying food is a central part of the human experience, so it’s natural that printing food attracts a lot of attention from the general public. Food makes the technology of 3D printing relevant and interesting to everyone.

Until recently, 3D printing food required a specialized printer. One of many reasons we’re excited about our Discov3ry add-on paste extruder, is enabling anyone with a desktop 3D printer to experiment with edible printing. The experiments outlined in this article don’t require the Discov3ry extruder, but it’s probably the most accessible tool for the job.

The possibilities for printed food go well beyond just extruding edible pastes. Nearly all fine gastronomy is a result of complex chemical reactions, so in this article we’ll discuss the potential for reaction-based printing. This is the process of printing one substance into another to trigger a chemical reaction with an interesting, and hopefully tasty result.

Alginate beads are a great example of a simple chemical reaction being used to create interesting new foods. They begin with two primary ingredients: sodium alginate and a calcium solution (calcium chloride, calcium lactate, or calcium lactate gluconate). Don’t let the chemical names intimidate you. Sodium alginate is derived from brown seaweed and is flavorless.

When sodium alginate drops fall into the calcium solution, the calcium ions immediately react with the alginate to form a gel. Since the drop is spherical, the result of the reaction is also a sphere. Because of the spherical shape, alginate beads are commonly called “caviar” in gastronomic circles. They are naturally quite flavorless, which allows you to influence the flavor by adding fruit juices, liqueurs, or anything else that suits you fancy.

So where does 3D printing come into this? The basic method of making this food “caviar”, is to manually dispense alginate solution into a bowl containing the calcium solution, one drop at a time. To step things up, you could put your bowl of calcium solution onto the stage of your 3D printer and use a repeating print cycle to dispense the drops. Using a printer will likely get you uniform drops every single time, and leaves you to focus on the other details like color and flavor combinations.

If that example is still too easy for you, you can use a 3D printer to print alginate “noodles.” To do this, you would use a longer needle on your extruder so that it can be submerged in the calcium solution. While submerged, the 3D printer then prints your noodle pattern. Instead of little caviar beads that explode with an interesting flavour, you now have this in noodle-like form. You could use this in a salad to release a dressing or with meats or vegetables to release a sauce.

A few pre-cautions: You have to pay attention to details like the acidity, or your alginate chemical reaction won’t work. You might also have to tune the viscosity of the calcium solution so as to allow the noodle to “stick” into the solution and not get dragged along with the tip. But there’s some interesting potential here.

For guidance on flavorings, here is some further reading:

Going to San Francisco...MakerFaire

"If you're going to San Francisco
Be sure to wear some flowers in your hair
If you're going to San Francisco
You're gonna meet some gentle people there"

-Scott McKenzie, 1967

 

Structur3d Printing is excited to announce that we will be heading to the Bay Area MakerFaire on May 17th and 18th; just a few weeks from today.  For those of you who are unfamiliar with what a MakerFaire is, well you are in for a treat.  Dubbed the "Greatest Show (and Tell) on Earth," MakerFaires are events where makers, tinkerers, inventors, teachers, artists - modern day renaissance folk - get together to share their creations with the globe.  Often compared as part country fair, part science fair, and part something entirely new, MakerFaires are held world wide, with over 100 MakerFaires happening in 2013.

Check out this short introduction to MakerFaire Bay Area 2011 to get a feel for the creative atmosphere at the show.

Structur3d Printing was accepted as one of only 16 start-up sponsors for the event, which is very exciting news for us and our supporters.  The event typically sees 100,000+ visitors over the weekend and we are taking this excellent opportunity to share our paste extrusion technology and vision with the Maker crowd.  We will be bringing along one of our prototypes to demonstrate the printing of various new and exciting materials - silicone, icing sugar, ceramic slip, and a even special surprise.

Please follow our adventure to the Bay Area; we will be updating our blog and posting regular updates to our Twitter and Facebook profiles.  Also, if you are in the Bay Area around May 17th and 18th, check us out at MakerFaire.  If you are not going to make it, we would still love to meet up, coffee on us.  Drop us a line.
