3D Scanning – Autodesk ReMake

The idea to 3D scan an object is very old. We have seen it in sci-fi movies and read about it in books. Recently, thanks to developed software like Autodesk ReMake we can implement this idea into life. This type of software is based on photogrammetry – the science of making measurements from photographs and mapping them between objects. Below, there is a list of tips on how to make pictures so that conversion software understands them best. Click on picture to zoom

3D Scanned and 3D Printed GW2 Cannon

We wanted to try this software in action ASAP and instead of taking pictures with a photo camera, we took plenty of screenshots from one of the 3D video games. A cannon in Guild Wars 2 was the best object for our learning purposes. It was small, solid, it didn’t move and wasn’t shiny. We took plenty of screenshots of the cannon from all angles. Then the folder with all screenshots was uploaded to ReMake.

3D Scan of GW2 Cannon in ReMake

It took around 20 min to complete the processing. That is when you can tell if your scanned object is successful or not. Don’t be afraid when you see your object as a tiny fragment in the middle of all sort of debris. ReMake offers different tools to clean the area, to smooth an object and make it 3D printable. In a slicer (Simplify3D) we added support and performed the last check before saving a G-Code. Bronze colour filament worked well for our cannon. We printed it in ABS filament with layer height 0.2. For a better result, 0.1 can be used. One day we will try acetone vapour smoothing to make our object smooth and shiny.
Pictures above show our cannon in ReMake before it has been cleaned, on a printing bed with support and the final result.

We also submitted our object as #designbycapture competition entry organized by Autodesk and MyMiniFactory. You can check more 3D printing related competitions here:

List of tips for successful 3D Scan

– For shiny or reflective objects, the only way to capture them is to make them stop reflecting light. To achieve this cover them temporarily in some matt solution. Otherwise, software will be confused and 3D scanning will fail.
– Focus and capture all pictures manually. Use Open Camera app for mobile phones.
– Avoid large areas of single color. It might leave holes in 3D scan.
– Make sure that your object stays still and not shaking while scanning.
– On and off sunrays during capturing your object may also confuse the software.
