3D Printing Parts
What is 3D Printing
3D printing is a Additive Manufacturing fundamentally different way of producing parts compared to traditional Subtractive (CNC machining) or Formative (Injection molding) manufacturing technologies. Every 3D printer builds parts based on the same main principle: a digital model is turned into a physical three-dimensional object by adding material a layer at a time. The images below will give you a better picture of 3D printing.
Advantages Of 3D Printing
One of the biggest advantages of 3D printing is summed up in two words: Rapid Prototyping, especially if you know how to optimize your product design to take advantage of them. Benefits include:
- 3D printing parts are fully dense, incorporating complex geometries and precise internal features that cannot be made with traditional machining alone.
- Since 3D printing uses only the required material and needs no tooling, it is one of the most affordable manufacturing processes for one-off parts or small batches.
- Once a part has been designed using CAD software, it can be printed in a matter of hours, without a lengthy setup procedure.
- Multiple, identical parts can be built on a single platform at one time, greatly increasing production efficiency.
The Different Types of 3D Printing Technologies and How to select
All 3D CAD files you wish to have printed must be provided for the design and reviewed by the production team so they can be optimized and made to meet design requirements. KAIAO provides a range of high-quality 3D printing services, including FDM, SLA, SLS and SLM. This allows for the 3D printing of plastics and metals, and provides options for both prototyping and production.
Overview the Different 3D Printing Services
Stereo lithography (SLA)
Stereo lithography makes use of a liquid plastic as the source material and this liquid plastic is transformed into a 3D object layer by layer. Liquid resin is placed in a vat that has a transparent bottom. A UV (Ultraviolet) laser traces a pattern on the liquid resin from the bottom of the vat to cure and solidify a layer of the resin. The solidified structure is progressively dragged up by a lifting platform while the laser forms a different pattern for each layer to create the desired shape of the 3D object.
Fused Deposition Modeling (FDM)
With this technology, objects can be built with production-grade thermoplastics. Objects are built by heating a thermoplastic filament to its melting point and extruding the thermoplastic layer by layer. Special techniques can be used to create complex structures. For example, the printer can extrude a second material that will serve as support material for the object being formed during the printing process. This support material can later be removed or dissolved.
Selective Laser Sintering (SLS)
SLS has some similarities with Stereo lithography. However, SLS makes use of powdered material that is placed in a vat. For each layer, a layer of powdered material is placed on top of the previous layer using a roller and then the powdered material is laser sintered according to a certain pattern for building up the object to be created. Interestingly, the portion of the powdered material that is not sintered can be used to provide the support structure and this material can be removed after the object is formed for re-use.
Selective Laser Melting (SLM)
The SLM process is very similar to the SLS process. However, unlike the SLS process where the powdered material is sintered the SLM process involves fully melting the powdered material.
