3D printing refers to the different procedures by which the physical construction of a 3D design can be achieved by additive manufacturing<\/strong>.<\/strong><\/p>\n

Differently to CNC machining, where the part is obtained from the subtraction of material from a starting block, in additive manufacturing, the geometry is obtained from the solidification of the starting material layer by layer<\/strong>.<\/strong><\/p>\n

Traditionally, this technique is more common for plastic materials, even if metal and other materials are becoming more and more popular. <\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

MJF \u2013 Multijet Fusion by HP<\/h2>\n<\/div>\n<\/div>\n
\n
\n
\n

This is the latest and most advanced industrial printing<\/strong> technology, which is why it is the one chosen by Proto&Go! for your projects.<\/p>\n

This machine has been developed by HP to obtain both prototypes and series of parts in materials such as Nylon – PA12 or flexible TPU<\/strong>, among others.<\/p>\n

The manufacturing speed and the resistance of the resulting parts are remarkable.<\/strong> Therefore, 100% functional parts can be obtained in just a few days and with a high resolution.<\/p>\n<\/div>\n

SLA \u2013 Stereolithography<\/h2>\n<\/div>\n<\/div>\n
\n
\n
\n

Stereolithography belongs to a family of additive manufacturing<\/a> technologies known as photopolymerisation, or commonly, resin 3D printing. The main concept of this technique is the use of a light source (a laser) to harden liquid resin and transform it into solid plastic. <\/p>\n

Parts made using SLA offer the highest resolution and accuracy, the sharpest details and the smoothest surface finish of all 3D printing technologies, making it ideal for aesthetic parts.<\/p>\n

On the other hand, they have a disadvantage in that, as the material is photosensitive, the pieces obtained do not withstand the passage of time or exposure to ambient light<\/strong> and are generally fragile<\/strong> for small cross-sections.<\/p>\n

For this reason, we, at Proto&Go!, prefer to opt for CNC machining of ABS<\/strong> to obtain parts for aesthetic purposes such as housings or fairings.<\/strong> <\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

SLS \u2013 Selective Laser Sintering<\/h2>\n<\/div>\n<\/div>\n
\n
\n
\n

It is a well established technology with which parts in Nylon, Polypropylene or other materials can be obtained by fusing powdered material by applying heat with a single-point laser.<\/p>\n

SLS is a pre-MJF technology with similar characteristics but without some of its advantages, such as material isotropy and manufacturing time.<\/p>\n<\/div>\n

\n

FDM \u2013 Fused Deposition Modelling<\/h2>\n<\/div>\n<\/div>\n
\n
\n
\n

This technique is often considered the most simple method existing. Fused Deposition Modelling or FDM technology is based on 3 main elements: a printing bed\/plate on which the part is printed, a spool of filament that serves as the printing material and an extruder. In summary, the filament is melted by the 3D printer\u2019s extruder, which deposits the material accurately layer by layer on the print bed.<\/p>\n

The most common materials for this type of printing, among others, are ABS and PLA.<\/p>\n

The big advantage of this technique is its simplicity and economy, making it the technology most widely used in the domestic sector.<\/strong> <\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

The process starts with a coating head that deposits a very thin layer (typically 0.08 mm) of the powder material, PA12 or TPA, on the construction platform. After the deposition of a first layer, a second moving head applies the agents on the part geometry that will delimit the area to be sintered by a melting unit incorporated in the head itself.<\/p>\n

Once the entire cross-section has been scanned, the construction platform lowers a layer thickness in height. The unsintered powder remains in place to support subsequent layers, eliminating the need for support structures..<\/strong><\/p>\n

The coating head deposits a new layer of powder on top of the previous, already sintered layer, and the head with the agents and the melter makes a new run to sinter the new section on top of the previously solidified ones. This process is repeated until all the parts are completely manufactured.<\/p>\n

The result is a container full of powder and solidified parts that must be left to cool for at least 24 hours before being removed.<\/p>\n<\/div>\n<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
