3D scanning

Students Photocopy Objects with their iPhones!

On Friday, April 5, nearly 20 University of Illinois students stopped by the MakerLab to learn how to photocopy objects with their iPhones. This session was taught by Katie Khau, a UI student in Art & Design and a MakerLab Trainer. Katie demonstrated how to photocopy objects using the new iPhone app, 123D Catch (www.123dapp.com/catch). As part of this demonstration, Katie printed out a small scale photocopy of a 3D printed replica of Rodin's "The Thinker" (www.thingiverse.com/thing:34343). She has also put up a tutorial, if you want to try this. If you have questions, please post on our Forums

In the coming months, we plan to offer more training sessions such as this. Our next session is a tutorial on Google Sketchup on Friday, April 19 from 12:00-1:00pm. To RSVP, email us at uimakerlab@illinois.edu or signup on facebook. Subscribe to our blog RSS feed to be the first to hear about events and other exciting news from MakerLab.

It's Easy as 123D Catch

So you want to learn how to 3D scan an object using 123D Catch? Don't worry it is easy to learn! 123D Catch allows you to create photo realistic 3D models from just photographs from your camera or iPhone. First you will need: - your object - a camera or phone - 123D Catch App

Taking the photos. - Make sure that you can move around your object when you take photos. - Take 20-40 photos from different angles around the object. (The more pictures the better!) - Tips: - No transparent or very reflective objects. - Don't move the object, only you move when you take the photos. - Make sure your object is on a unique background with lots of details, place newspapers down if necessary, and put the object on them.

Upload your photos into the 123D Catch Cloud. - Either download the software if you have a PC or iPhone or load up the app in your browser and launch 123D Catch (Both can be found here) - Click on "Create a new photo scene" - Find all the photos you have taken and click "open" - Click on the "green checkmark" and type in your name and email, then agree to the terms - Confirm your email and type in a name for your project and then click "wait" - After all of your photos are uploaded, click on the prompt that will let 123D Catch send you an email when the 3D Model is complete - All of the heavy computing to create the 3D model is done in the cloud freeing you and your computer from processing time - 123D Catch should close when you click "ok"

3. Getting your 3D model - When your 3D model is done you will receive an email that has a link for you to download your file - Download and save the .3dp file on to your computer/phone - Back in the 123D Catch app, open up this file that you just downloaded - You have now just created 3D model using the photos you have taken!

Cleaning up your 3D model - You can clean up your model directly in 123D Catch by select and delete certain parts of your mesh that are not necessary to 3D print (be careful though because there is no undo button) - You can also edit the model in Netfabb or other 3D CAD software.

And there's your model! If you have questions, please post on our Forums

Come on into the Makerlab on Friday, April 5th from 2-4pm for a workshop to 3D scan for yourself!
