3D Printing Technologies

The choice of 3D printing technologies is dependent on the product to be manufactured, design, material and technicalities. Processes included in 3D printing Technologies are: FDM (Fused Deposition Modelling), SLS (Selective Laser Sintering), Polyjet, Voxeljet and DMLS (Direct Metal Laser Sintering). The most common using 3 Dimensional Printing technology is FDM. It is possible to produce plastic and metal parts with these technologies. Some use material in form of filament, others in form of powder. 3D Printing technology’s working principles are different from each other. Namely, we can explain that pieces are produced by controlling x,y and z axes through the production platform. You should contact a technology consultant to choose a 3D Printer. If the right 3D printing technology isn’t choosen, Your pieces could break or couldn’t have the right measurements and this situation might be the cause for taking much more time and a costlier production.

FDM Technology :

FDM is named as fused deposition modeling. In FDM technology, plastic raw material is conveyed into an extrusion headpiece with the help of a motor. Material melts with temperature at this place. An extrusion headpiece lays off the molten material onto an empty platform and so it sets the first layer that’s going to constitute the piece. The platform moves one step down with every layer, thus all the layers form the final shape.

Firstly, the CAD Model is defined, then transferred to STL file format. The filament spools can consist of several ABS and PLA materials of about 1.78mm diameter. During production via FDM technology, the printing material and a support material are used for the main piece construction.

When an object is out of the FDM printer, support materials are pulled off and removed with hand. Filler paintings can be applied on the model’s surface when producing with FDM technology.

Materials and fields of usage :

•      Abs
•      Pla
•      Flex
•      Nylon
•      Carbon Fiber
Architectural, Model, Education, etc.

SLS Technology :

The technology of binding via heating is named laser sintering. The material is formed when it’s heated by laser beams and the powder particles fuse together. Laser scanning is applied on the predetermined areas with the CAD software, so the resultanting heat is applied on the areas that the laser beam hit and this causes the fusible powder particle’s sintering. Supporting material can’t be used in this technology.

The biggest advantage of SLS is the non-necessity of supporting material, making it capeble to produce consequent layers. SLS is used in dynamic prototype pieces production such as hinges, clips and tabs. Predominantly, polyamide and derivatives are used in SLS technology.

Materials and fields of usage :

  • Polyamide ( PA 2200 )
  • Nylon

Industrial, Automotive, Aviation Etc.
Steady, Prototype for resistance to impact and high temperature

POLYJET Technology :

A light-curing polymer is applied to a work platform through a print head with several nozzles. The layer is formed at ambient temperature, sprayed on a 16 micron tray that’s formed by 1536 ejector. The resin is cured by an UV light and therefore becomes solid. The tray moves one step down with every layer.

The support material is sprayed with the main one and at the end the support is separated with mechanic methods after which the model is post-cured.

Materials and fields of usage :

Photo-Polymer Resin
Industry, Architectural, Model, Medical Etc.
Flexibility for the construction of the model, Aesthetics and Durableness

SLA Technology :

The scanning cure technology with light is named as SLA (Stereolithography). In this technology, a liquid phase photo-polymer resin layer becomes cures with an UV spot laser beam.

The laser beam moves with the help of a CAD software, scans the piece’s geometry on the resin coat and creates the layers. After the layers are finished, the piece is taken off from the resin pool. The supports are mechanically seperated from the piece. According to the material type, if an additional cure is needed, this happens with the help of the UV light.

Materials and fields of usage :

Photo-Polymer Resin
Jewellery, Dental, Architectural, Medical Etc.
Flexibility for the construction of the model, Aesthetics and Durableness

SLM Technology :

SLM is named as selective laser melting. Laser beams melt metal powder on the layer and directly produce metal pieces from the 3D CAD file.

This process is very fast and sensitive, and almost all metal powder materials produce a high fidelity layer prototype.

Materials and fields of usage:

  • Bronze
  • Steel
  • Carbon
  • Titanium
  • Aluminum

Fields of implementation;

This technology is used for visualizing prototypes. 3D printing and 3D scanning is also used to copy ancient and precious structures for archaeological purposes. Especially in the manufacturing sector, given the progress of the technology, using 3D printing method provides a faster and more productive manufacturing process.
