Rendered part with a bump map applied allowing the light to interact with the part This typically results in a part that looks very realistic from a distance, but a closeup look at an acute angle reveals that the model geometry is flat. A bump map, for example, is used in animation to provide instructions to the computer rendering engine about how the object should interact with the light.This technique also uses an image texture to achieve a certain colour or photorealistic effect (as above), but it can also include image textures that control other aspects of the model such as surface height, reflectiveness, roughness etc.We will be using the word “texture” a lot, so it is important to keep in mind that we are referring to an image or graphic and not necessarily a surface finish.Ģ) Bump and displacement mapping: Fully mimicking real-world materials in terms of both colour and physical touch When these elements are applied to a model they are referred to as an image texture.The advanced design techniques mentioned above can be divided into two sub-groups:ġ) Image textures: Where graphics such as logos, text, images, and barcodes can be applied Now lets look at some of these concepts in more detail: Step 1: Exploring the enhanced design capabilities of the J750/J735.įirst lets take a look at a what a texture is and some of the main types that can be applied to models for 3D Printing.

In future tutorials we will investigate how to quickly use these tools to achieve fantastic realistic parts. This tutorial will explain the theory behind how these effects are applied. It can also produce models with surface finishes that mimic various materials, such as leather and wood. In our previous tutorials, we discussed applying colour to 3D printed models.īut the Stratasys J750™ and J735™ also have more advanced capabilities, including the ability to create photorealistic lifelike product models incorporating company logos, detailed text, and graphic elements.
