If you need assistance in finding which 3D printing process is the right fit for you, you can set up a consultation and planning phase with our team of additive manufacturing experts.
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. These requirements will differ between FDM, SLA, SLS, and SLM 3D printing, so be sure to optimize your CAD model for the 3D printing process you wish to use.
Selecting the right 3D printing process depends on many factors, including the purpose of the part, its size and its material. XTJ can help you decide on the appropriate 3D printing technology for your project.
3D printing services we offer:
1.FUSED DEPOSITION MODELING (FDM)
Modelado por deposición fundida
Fused Deposition Modeling (FDM) is the most widely used additive manufacturing process for desktop 3D printers. The process involves extruding a melted plastic from a computer-controlled nozzle, building a part layer by layer.
FDM 3D printers use a spool of filament as raw material. This filament is directed into the print head, where it is melted and deposited onto the incomplete part. In accordance with computer instructions, the print head moves along 3 axes in order to deposit material in the right place.
Because the material cools after it is deposited, further layers of material can be deposited on top of the existing layers, allowing for the creation of 3D shapes.
FDM is also known as Fused Filament Fabrication (FFF).

Material options
Widely available
Desventajas
Comparatively low resolution
Produces visible layer lines
Typical accuracy
± 0.5% (desktop)
± 0.15% (industrial)
Typical layer height
50-400 microns
FDM Materials
PLA: The most widely used FDM material, PLA (Polylactic Acid) is affordable, stiff and strong. It also comes in many colors and blends.
ABS: Another common FDM material, ABS (Acrylonitrile Butadiene Styrene) is also resistant to high temperatures.
PETG: PETG (Polyethylene terephthalate) has high impact resistance and good thermal characteristics. It is also food safe.
Nylon: Tough and flexible, nylon is strong and resistant to wear and chemicals. It is, however, vulnerable to humidity.
TPE/TPU: A blend of plastic and rubber, these thermoplastic filaments produce highly flexible parts.
PC: PC (Polycarbonate) filaments produce extremely strong parts that are resistant to heat and impact.
2.STEREOLITHOGRAPHY (SLA)
Precision CNC Milling
Stereolithography (SLA) is an additive manufacturing process that works in a different way to FDM. In SLA 3D printing, a 3D object is created with a laser, which is directed at areas of photosensitive liquid resin. The laser causes areas of the resin to harden, forming a solid part.
The SLA process uses a moving platform in a tank of liquid resin. The platform moves up or down after each layer is fully cured, which is different to FDM, in which the platform remains stationary. The SLA laser is focused using a system of mirrors.
SLA can only be used with photosensitive polymers, but offers high accuracy and fine details. It also predates other forms of additive manufacturing, having been invented back in the 1980s.
Ventajas
High resolution
No visible layer lines; smooth finish
Option of clear materials
Desventajas
Printers more expensive than FDM
Weak parts will degrade with sunlight
Extensive post-processing required
Typical accuracy
± 0.5% (desktop)
± 0.15% (industrial)
Typical layer height
25-100 microns
