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)
Sulautettu kerrospainaminen (FDM)
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).

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.

An SLM 3D printer uses a gas-filled chamber containing the metal powder. The laser passes over the desired sections of the powder, causing the particles to melt and bond. When a layer is complete, the build platform moves down to allow the laser to pass over the next layer.
The SLM process can be used to create strong metal parts with highly complex shapes, providing engineers with new levels of design freedom.

SLM Materials
Titanium: Titanium alloys (6Al-4V and 6Al-4V ELI) can withstand high temperatures, offer a high strength-to-weight ratio and are resistant to corrosion. Can be heat treated for superior strength.
Aluminum: Aluminum alloys (AlSi12 and AlSi10Mg) provide strength and hardness, and work well with complex shapes or parts with thin walls.
Stainless Steel: Stainless steels are resistant to wear, corrosion and abrasion.
Cobalt: Cobalt-chrome alloys offer high strength, hardness and resistance to high temperatures.
Nickel: Nickel alloys are resistant to heat, corrosion and oxidation, and create parts with strength in high-temperature environments.
Precious Metals: Metals like gold, silver and platinum are ductile and provide a desirable appearance.
