Multi-material 3D printing is the additive manufacturing procedure of using multiple materials at the same time to fabricate an object. Similar to single material additive manufacturing it can be realised through methods such as FFF , SLA and Inkjet (material jetting) 3D printing .
The plastic nurdles are always white or clear. Pigments or other additives are added to the material before it is melted to create coloured filament or filament with special properties, e.g. increased strength or magnetic properties. Before the filament is extruded the nurdles are heated to 80 °C to dry it and reduce water content.
3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. [1] [2] [3] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, [4] with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.
Computer-aided design (CAD) model used for 3D printing. The manual modeling process of preparing geometric data for 3D computer graphics is similar to plastic arts such as sculpting. 3D scanning is a process of collecting digital data on the shape and appearance of a real object, creating a digital model based on it.
Nylon is a family of synthetic polymers characterized by amide linkages, typically connecting aliphatic or semi-aromatic groups.. Nylons are generally white or colorless [1] [failed verification] [2] [failed verification] and possess a soft texture, with some varieties exhibiting a silk-like appearance.
Alumide is a material used in 3D printing consisting of nylon filled with aluminium dust, its name being a combination of the words aluminium and polyamide.Models are printed by sintering a tray of powder, layer by layer. [1]
Nylon 12 exhibits properties between short chain aliphatic nylons (e.g., nylon 6 and nylon 66) and polyolefins. [3] At 178-180 °C, the melting point of nylon 12 is the lowest among the important polyamides. Its mechanical properties, such as hardness, tensile strength, and resistance to abrasion, are similar to those of nylon 6 and nylon 66.
It is used for general prototyping in 3D printing, where its UV resistance and mechanical properties make it an excellent material for use in fused filament fabrication printers, [1] particularly for outdoor applications. ASA is also widely used in the automotive industry. [2]
