Our Printer – Cat NOT included

3D printing in my classroom has taken over my life. I need to go to 3DPA (3D Printing Anonymous) post-haste. Last night was the final straw as I was flopping and flipping about, trying to figure out how I am going to get 30 student 3D print jobs completed before the end of the year.

Since this very cool piece of machinery arrived in my classroom May 1st, I have been doing everything in my power to get the kids up and running. Creating their own 3D objects to print before year’s end. The main focus has been figuring out how kids can create bobble heads of themselves.

The machine we decided to purchase the Flash Forge 3D printer based on the reviews we found on-line and ultimately the price point. As conscientious educators, we had to seek out a product that would provide us the most bang for our buck and I think we hit the mark. So far the printer has been bomb-proof and worked right out of the box. One of the extruders is a bit finicky but I think it is just a simple matter of finding the right setting. The biggest challenge is capturing an image that you can actually print.

We have had a varying success over the past three weeks trying to capture and render a 3D image of ourselves. Our first go round we were following a guide from a website called Instructables. It used an app called 123D capture to collect our images and render a 3D model. Unfortunately, of the 30 kids in the class, only 4 of them managed to capture and render an 3D object worthy of printing.

This is not to say that this particular method wasn’t any good just that it wasn’t intuitive or efficient enough to get a classroom of 30 kids up and running without a lot of hand holding and troubleshooting. I would still recommend reading the guide as it has a lot of good information for preparing the capture for printing so it is still worth a perusal.

Enter Skanect

I stumbled upon this bit of 3D capture software while looking for another method of capturing 3D images that was quicker and less fussy. Essentially it is a brilliant piece of software that allows you to hack the scanning power of the XBox Kinect and employ it to do a 3D scan of pretty much anything you want.

Now all I need to do is connect my Kinect to my laptop using a $2.99 adaptor from Amazon, fire up the software, sit a kid down in an office chair, line them up into the scan zone and tell them to slowly rotate around for 30 – 50 seconds. Voila! Bob’s your uncle and you have a 3D scan of yourself.

The following scan of pretty old me took 15 minutes from scanner to printer. Kids work coming soon.
