What Types of 3D Model Databases Are Available?

Conclusion

To design a 3D model from scratch is very time-consuming. Therefore, it is great that these 3D model databases exist. Even if you cannot find the 3D model you are looking for, it’s still a good starting point to build upon an existing 3D model or modify it.

Are you looking for a 3d model that can’t be found in any 3D model database?

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 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.

Lecture on reverse engineering (3D scan and CAD)

Swann Rack from Holocreators gave a presentation on reverse engineering at the Rapid.tech 3D Congress 2018. Reverse engineering allows an object to be reproduced using 3D scanning and subsequent conversion into a CAD format. In his presentation, Swann Rack talked about the different 3D scanning techniques and how the reverse engineering process works.
