How to 3D-scan people or animals?

With the help of specialized 3D scanners, you can 3D-scan people and animals. This allows you to create 3D models that can be 3D-printed or used for 3D animation. We'll show you three different devices that make such 3D scans possible.

What is Kitbashing?

Kitbashing is associated with model making. It is composed of the words "Kit" and "Bashing". “Kit” refers to "model kit". So, when a model maker is "kitbashing", he blends parts from different model kits. Similar to a collage. The model maker combines several individual models into an entirely new model.

What Types of 3D Model Databases Are Available?

We have compiled a selection of 3D model databases. You can download 3D models and then edit them in a 3D program or 3D print them. There are databases with free 3D models and those that sell them.

What is Reverse Engineering? (Converting a 3D-Scan to CAD)

Reverse engineering is required whenever a 3D scan (STL format) needs to be converted into a CAD model (STEP format). We will give you a brief overview of three different reverse engineering techniques.

What is the difference between NURBs model and a mesh?

A NURBS model consists of points connected by curves. A polygon mesh consists of thousands or millions of small triangles. CAD surface models are usually created using NURBS surfaces, while 3D scans are typically exported as a polygon mesh. The conversion from a polygon mesh to a NURBS model is called "reverse engineering".

Reverse engineering and error propagation

Reverse engineering enables us to create a copy of an object. For this purpose, the part is 3Dscanned, then the 3D scan data is converted into a CAD format, and finally, the part is manufactured. All these steps result in noticeable deviations. If an error adds up over multiple steps, then we call this error propagation.
