3D-Printed Bike Reduces Design Time to Days

3D-Printed Bike Reduces Design Time to Days

July 30, 2018

A start-up company called Arevo is pioneering an environmentally friendly 3D printing process.

3D printing with carbon fiber has not produced a recyclable product…until now. Arevo’s new process incorporates thermoplastic with carbon to make the process and printed product recyclable.

Currently, Arevo is using the new process to print bikes.  The company has designed software that can be used to test the design before printing which further saves energy, materials and time.  The result is that the typical time frame for designing a new bike can be reduced from 18 months to 18 days.

Discussion Questions:

1. How could Arevo’s 3D printer change the current bike supply chain?

Guidance: The current supply chain involves mainly manufacturing bikes in China and subsequent distribution globally.  Students should be asked to draw the current supply chain, e.g. suppliers sending materials to China, Continue reading

Continuing Safety Problems in the Food Supply Chain: Pre-Cut Melons, Veggie Trays

Continuing Safety Problems in the Food Supply Chain: Pre-Cut Melons, Veggie Trays

July 15, 2018

Safety related problems continue with our food supply chain.  Cut melons were recently recalled across 8 states with over 60 people becoming ill due to a salmonella outbreak. Del Monte’s pre-packaged veggie trays accounted for over 200 cases of infection by the Cyclospora parasite  in June and July.

Safety and recalls in the food supply chain were featured in a previous OM In The News blog.  Other recent issues include an April recall of over 200 million eggs over salmonella fear, Kroger’s recall of over 35,000 pounds of ground beef contaminated with hard pieces of plastic, and in May, a recall of romaine lettuce grown in the Yuma, Arizona area impacted over 20 states.

These continuing safety problems bring to light problems in our food supply chain.

This post is based on the CNN.com post, Multistate Salmonella Outbreak Linked To Pre-Cut Melon, by Susan Scutti and Jen Christensen, June 9, 2018; and on the Food Safety News article, Two dozen more confirmed in parasite outbreak linked to Del Monte (no author cited), July 7, 2018.

The Ingenious Design of a Food Truck

The Ingenious Design of a Food Truck

Today’s food trucks bear no resemblance to the traditional food trucks at state fairs. They are mobile kitchens designed to please the most discriminating foodies. How can they deliver culinary feats in such tight spaces? With efficient layouts and the multi-faceted talents of the people who operate them.

Community fundraising events, such as the Eugene Food Truck Festival in Oregon, serve to expand the reach and popularity of food truck operations, while changing regulations and permit requirements pose a challenge in many locations.

This post is based on the Washington Post article, What’s in a Food Truck?, by B. Berkowitz, S. Blanchard, A. Steckelberg, and M. Ulmanu, May 14, 2018; and on the Daily Emerald article, Eugene Food Truck Festival attracts 12,000; raises funds for Eugene Mission, by E. Matlock, July 9. 2018, and the USA Today article, Regulations and permit headaches keep food trucks from cruising down Easy Street, by Z. Meyer, June 12, 2018.

Discussion Questions:

1. What are the basic equipment requirements for a food truck?

Guidance: See the interactive graphic shown in the article: freshwater and wastewater tanks, freezer, refrigerator, generator to power Continue reading
