stem bridge project 3d models

This is just an example used in my Middle School curriculum. Feel free to add suggestions/download for use. *Please let me know if there are any problems. ...I'm still new to the 3D Printing world.

*I did not add a support beam on the second column on both sides simply because I was planning on laying a small road in between so the students could test various loads with different vehicles crossing their bridge. This can be altered very easily...

This is my project that I submitted from Northside High

This is our bridge project. Our bridge is the second best in the class. Have a ratio of 1000lb/g. There is two type of members. One is 75% infill another is 100% infill, I show both of them in the top. They all have a 0.1-inch diameter. I'm so...

Every members are print at 90% infill, our weight is 38.6 Pound and ratio is 266. ...Our bridge is supersize me because it work out well at last since we had do reprint and have some issue with it but it still show a pretty good job.

This bridge was the starting design for students to improve upon as part of a public schools STEM project lead by a public and private partnership between the: 1. the US Army Engineer Research and Development Center (https://www.erdc.usace.army.mil/)...

... certificates at the end of the year. ...Print out 3-D awards. I give this badge to my top 3 toothpick bridge builders. Instructions Prints using .20mm and 10% infill. ...Prints in less than 1 hour.

3D bridge project Anna & Anna

a strong bridge

This is a Pratt-Truss Bridge with 6 rectangles

could not find a bridge easy enough to build out of wood offcuts.

Eight of the long members are 100 percent infill; all of the short members and four long members are 25 percent infill.The weight of the bridge is 36.9 grams; the weight of the weight is 8890.4 grams. ...The load to weight ratio is 240.9.

Pill Bottle components

This was an 8th grade 3D modeling project. This bridge was able to hold up to 17 lbs of water. ...Students had to design the model in SketchUp.

This was a semester-long AutoCAD IV project for a student entering a Civil Engineering program next year. The bridge held 5 + lbs. on each span (live and dead weight). ...

The bridge cuts through the big mountains

Did this for a friend, her kid needed to make a replica of the golden gate bridge for school, is made of cardboard, elastic, straws, nylon and paint. ...Using glue and staples.

My first non-school work. ...I started a few weeks ago in school with rhino and i'm a fan of bikes so i made a Stem. ...I hope you like it!
