3D Scan Reverse Engineering

Krossdal Gunstock in Iceland create fantastic custom made hunting rifles and products around weapons.

We were tasked with reverse engineering a 3D scanned hand-made wooden rifle so that it could be redesigned and adapted for different action modules

From reality to CAD

Krossdal did all their own 3D-scanning and had already created some of the basic 3D shape needed for the project so we had a solid base to start from.

When it comes to rifles, they usually have a very interesting mix of organic and mechanical parts which can be hard to get right from the first time.

Having access to CNC-milling lets you try out your design and really get a feel for it.

Krossdal puts in a lot of extra work, sanding and filing down the wood so it feels 100% correct, something that is difficult to do in the computer from the beginning.

A 3D Scanner can then take in the real-world, hand-processed reference model and present it in 3D-space.

Mesh only gets you so far

Currently 3D Scanning only leaves you with a mesh file (triangulated model) that can be considered a dead reference. That means that you cant precisely modify it or make changes to the file. For some type of 3D-scanning, that’s totally fine, but when it comes to product design, engineer, milling and a few other scenarios, what you need is a CAD-file.

This is one of the things we specialize in here at 3D Consulting Nordic.

We take 3D scanned mesh (or 3d scan for you) and create CAD-data for your needs. May it be CNC-milling to cast copies or reverse engineer a hand-made product.

The Before and After

In the slider to the left you see first the mesh-data we got to work from.

We remodeled the mesh into a fully editable CAD-file, creating a flexible and future-proof model for Krossdal Gunstocks product development.

Krossdal Gunstock Machining

Krossdal then finished of the model, adapting it for their action, grip, buttstock and other accessories.

Finally it was time for machining and the final result looks amazing!
