3d printing technology

3d printing SLS: selective laser sintering

What are the benefits of SLS?

01

Cost-effective production of high-quality parts without the use of expensive conventional forming tools

02

Durable engineering materials

03

High dimensional accuracy and reliability of the SLS process

Selective Laser Sintering (SLS) technology belongs to the Additive Manufacturing Powder Bed technologies. This technology is used in many industries, from automotive, aviation and medicine to the largest companies providing 3D printing services. It has one of the largest 3D printing production potentials.
Data from a layered 3D digital model (e.g. designed in a CAD system, obtained during 3D scanning) is used to control a laser beam that sinters a cross-section according to model geometry. After sintering the layer, the work platform is lowered and a new layer of material is dosed. The sintering process is repeated until the complete part geometry is produced. Support structures are not required in the SLS process, which is a big advantage of this technology.
The SLS system we use offers a unique solution: open parameters, which allow for the optimization of the technological parameters, adapting them to your application.

3d printing MJF

What are the benefits of MJF?

01

High productivity

02

Cost-effective production of high-quality parts without the use of expensive conventional forming tools

03

Parts after optimization may have better parameters and unique properties

04

No need for supporting structures

Multi Jet Fusion (MJF) belongs to the Additive Manufacturing Powder Bed group of technologies. It has one of the largest production potentials in the 3D printing industry. Similar to SLS technology, MJF models are built in layers, but the way the heat energy is delivered is solved by selectively increasing light absorption and by spraying black dye onto a powder layer, and then welding the selected section with a lamp as an energy emitter. The shaded sections absorb more energy and the layer is solidified with the previous layer. This technology gives the possibility to make both prototypes and utility parts. Models are light gray, they can be colored black or another dark color.

3d printing FDM/FFF

What are the benefits of FDM / FFF?

01

Relatively low price of FDM / FFF 3D printed parts due to low material costs

02

High flexibility of 3D printing

03

A wide range of materials, including high temperature materials (e.g. ULTEM, PEEK)

In FDM/FFF technology, the material in the form of a filament is processed. It is heated and extruded by the nozzle into the device work area. FDM and FFF technology are one of the most popular 3D printing technologies. Please note that the quality of 3D printed parts depends on the FDM / FFF system used. The best results are achieved through the use of professional FDM / FFF systems.
The material is layered, and the way it is applied allows you to print closed spaces and those with reinforcing fill. The technology is successfully used in the production of functional prototypes, small series and tooling production. In advanced geometries, support structures are required. If support structures cause problems in your project, check out SLS.

Stereolithography (SLA) / Digital Light Processing (DLP)

What are the benefits of SLA / DLP?

01

High precision and smoothness of 3D printed parts

02

A wide range of materials

03

The possibility of producing parts with high transparency

04

Specialized materials intend

In resin technologies, SLA (stereolithography) DLP (digital light processing), the processed material is a material in the form of a photosensitive resin. The polymerization process is carried out by the laser energy (SLA) or matrix (DLP).
Livestock technologies are used in a wide range of applications, e.g. automotive, biotechnology, medicine and jewellery. High precision of parts and a wide range of materials constitute additional advantages of these technologies. Advanced geometry requires support structures. In most cases, they must be removed mechanically. If support structures cause problems in your project, check out SLS.

PJ (Poly Jet) / Multi Jet Modelling (MJM)

What are the benefits of PJ / MJM?

01

High resolution and dimensional accuracy of 3D printing thanks to the ultra-thin layer thickness (from 16 µm)

02

Possibility to produce multi-material and multi-colored parts

03

Material variety (from rubber-like materials to hard materials)

04

Relatively easy post-processing - supporting structures removed with a water jet

In resin technologies PJ (Poly Jet) and MJM (Multi Jet Modeling) the processed material is a material in the form of a photosensitive resin. The polymerization process is carried out through the UV lamp energy which realizes the polymerization of selectively superimposed sections of the produced model.
Resin technologies are used in a wide range of applications, e.g. automotive, biotechnology, medicine and jewelry. High precision of parts and a wide range of materials constitute additional advantages of these technologies. Advanced geometries require support structures that in most cases can be removed relatively easy with dissolution or rinsing. If the supporting structures cause problems in your project, check out SLS.

Direct Metal Laser Sintering (DMLS) / Selective Laser Melting (SLM)

What are the benefits of DMLS / SLM?

01

Parts weight optimization - topology

02

Geometric structures production that can be made only by 3D printing - e.g. cooling channels for tools (conformal channels)

03

Difficult-to-cut materials processing - e.g. nickel alloys

04

Meeting high-quality requirements for advanced industries - aviation, medicine

The DMLS (Direct Metal Laser Sintering) and SLM (Selective Laser Melting) technologies belong to the same group of 3D printing technologies: powder bed technologies. Both technologies enable 3D printing in the metal of the currently most popular metal alloys. Technologies differ only in certain technical solutions that are patented by one manufacturer or the other.
The 3D printing process is similar to SLS technology. An alloy powder of the selected metal is the feedstock. In metal Additive Manufacturing technologies it is required to use supporting structures to connect the built model with the machine platform and for certain geometry angles for the built part. The supporting structure is designed to support a given structure but also helps in the proper dissipation of thermal energy. The most commonly used layer thicknesses in metal 3D printing technologies is 30-60 µm.

Postprocessing

We constantly analyze the needs of customers. To this end, we have developed a number of finishing treatments that significantly improve the properties of 3D printed parts.

Surfacing

It allows you to smooth models made in any technology by using abrasive media in a vibratory drum. The surfaces gain a smooth surface as if sanded with sandpaper. The treatment is especially recommended for medium-sized models and round-shaped surfaces of low detail.

Gallery before/after:

Vibro

Our own print smoothing system gives SLS and MJF a light sheen with a delicate texture. Dyed parts receive a similar appearance to parts made with injection technology. Smoother models are more resistant to dirt compared to raw print. The advantage of this treatment is the possibility to obtain a smooth surface without the need for varnishing or grinding.

Surfacing + Vibro

By combining a number of finishing treatments, which mainly include the surfacing and vibro mentioned above, we can achieve even smoother surfaces in printed parts. There are some limitations to this treatment, which you will learn about after contacting the Fibometry team.

Gallery before/after:

SLS/MJF dye coloring

SLS/MJF prints can be surface dyed and freely coloured without adding thickness to the model. It is possible to create a color at the customer's special request. MJF printed parts are best dyed black because of their gray color.

Gallery before/after:

Painting

We offer print painting in all technologies.

Sealing

If your printout needs to be waterproof, SLS and MJF prints can be sealed which closes the porosity of the structure.

Mold release agent coating

In the case of mold or tool printed models, it is possible to cover them with a separating coating Mold release agent.

Laser marking dyed printed parts

The marking is possible for black-dyed printed models.
