3D Printing

PRINTING 3D-TECHNOLOGY

When we talk about 3D printing, we refer to a number of processes that make it possible to produce three-dimensional objects from a digital file. The creation of the object is achieved through material addition processes, in which layers of plastic, metal or another material are laid down successively to form entire models.

The current market offers a great amount of 3D printing technologies that are distinguishable by the way the material is laid down in layers. In Tecnoimpre 3D, we specialize in one of the most efficient and reliable technologies of the market: Fused Deposition Modeling (FDM).

Fused Deposition Modeling is a process in which a thread passes through a nozzle warmed to a higher temperature than the fusing point of the material used; therefore, said thread starts to melt or soften, and then it can be set down layer by layer with the help of servo motors that move the nozzle around, according to the coordinates indicated by the digital design.

3D printing appeared at the end of the 80s, but it has become popular in the last years due to process simplification and cost reduction. Nowadays, this attractive technology is one of the most useful tools in the fields of design, architecture and engineering because it allows us to bring into the real world now what we could only see through a screen before.

Efficient Cycle:

3D printing resources lower costs in different levels, since we do not depend on the expensive moulding and injection technologies, which are only useful to produce thousands of pieces. Now we can create a single piece without worrying about details, such as the die tooling or labor costs. When using 3D printers, you can produce, test, modify and improve a single piece in a couple hours. This is a method that helps you save time and money; more importantly, it also increases product quality.

Unique Shapes and Structures:

Traditional manufacturing and prototyping methods depend on the formal limitations presented by the cutting and moulding technologies; this reduces the potential shape options. With common manufacturing processes, we have to be carefully precise with the technical difficulties (i.e., wall widths, demoulding angles, and complex internal structures). This is not the case with 3D printing, for we can mould structures layer by layer, where the only limit is their creators’ imagination.

New Combinations:

Combining materials is not always possible with the traditional production techniques because of the high prices that come with reaching a balance between the physical and chemical properties of two different materials in the same manufacturing process. In the 3D printing world, this limitations do not stop such combinations, since hundreds of materials are already available to be used as printing raw material: from the trustworthy thermoplastics all the way to metals such as aluminium and silver, and even ceramics. All of that without counting the amount of materials that are currently under development, being adjusted to be utilized in 3D printing systems.
