Future Stair Repair: 3D Scanning/ 3D Printing.





Introduction: Future Stair Repair: 3D Scanning/ 3D Printing.

It can be quite frustrating when you finish remodeling a kitchen counter or building a stair case and only a couple weeks later a giant chip appears. This very thing happened at our Pier 9 workshop, when a very noticeable chip appeared on our staircase.

Traditionally, people might fill in the chipped spot with epoxy or carpenters glue. But where's the fun in that?

We busted out our Artec Eva 3D Scanner and printed a replacement piece. Here's how our OCD Stair repair went down.


1. 3D Scanner:
We used the Artic Eva 3D Scanner. The instructable on how to use them can be found here

You can also use 123D Catch (http://www.123dapp.com/catch) and your Smartphone camera to scan an object.

2. 3D Design software:
Using Artec Studios we were able to Scan the chip and clean up the model.
We then exported it as an STL.
Next, we uploaded the model into Meshmixer to create the reverse section.

3. 3D Printer
We printed our piece on the Objet Connex500 in Vero White and carefully cleaned it in the water powerblaster.

4. Instillation
Clean out the chipped area.
Applied Super Glue.
Waited to dry.
Sanded the are around the printed part and wooden stair.

    I will be posting a much more in-depth instructable going into using the Eva Scanner in the future. And a demo on how to get reverse geometry from a 3D sketch using meshmixer in the future.

    dude I walk up the stairs everyday. i thought that was some kind of plastic wood filler. turns out it is not that ordinary. amazing.

    This is amazing and so useful! Having a 3D Printer around the house is so handy.

    You opened the STL in Inventor? How?

    You just open the file, in the 'open' dialog, change the file type using the drop down button to the right side of the 'file type' field.

    Thanks. Modifying the part is a little tricky - difficult to even sketch and extrude on surfaces.

    Here's a cool instructable you might find useful on meshes in inventor...


    Try downloading meshmixer. It's a free mesh editor that can edit Stls. It is super easy to bring in a stl and get the reverse geometry.

    Wow! Imagine the potential for fixing complex cracks or damaged pieces of ancient artifacts etc. simply by printing out the crack's negative and placing it inside! Brilliant!
