3D PRINTING

3D PRINTING

Competition in the industrial products market has grown rapidly in the recent years. The decisive factors are the time of launching new products and the efficient use of material resources. Rapid prototyping with 3D printing technology allows you to get accurate and complex physical products in a short time.

 

We dispose with a wide range of technologies for rapid creation of accurate prototypes, like for example SLS (Selective laser sintering) or DMLS (Direct metal laser sintering). These are additional production technologies which create parts layer over layer, allowing model creation directly from 3D CAD.

  • 3D PRINTING allows, as early as the initial phase of product development, to practically verify and test the relevance and function of components.
  • Fast prototype creation with complex shapes contributes to the fast product launching into production and on the market.
  • Uncovering errors at the beginning of product development process brings cost savings to the company.

 

DESIGNATION FOR DESIGNERS AND ENGINEERS FROM AREA:

Automotive industry / Industrial machinery and equipment / Aviation industry / Consumer electronics / Consumer goods / Art and design / Architecture

 

Used printing technologies:

The Fused Deposition Modeling (FDM) process constructs three-dimensional objects directly from 3D CAD data. A temperature-controlled head extrudes thermoplastic material layer by layer.

Applications:

Functional or aesthetic validation

Fit, form testing prototypes

Obtaining high-quality parts

Producing shapes accurately (lids, shells, etc.)

 

Some good reasons to choose FDM:

High accuracy

Functional parts

Prototypes directly constructed in production materials (ABS in various color, PC, PC-ABS)

Durable parts with great stability

 

Z Corp 3D printing uses standard inkjet printing technology to create parts layer by layer by depositing a liquid binder onto thin layers of powder.

Applications:

For evaluation of the look, feel, and style of product designs

High-definition 3D printing models with complex geometries and small, detailed features

 

Some good reasons to choose Z corp:

Fastest 3D print speed

Produce realistic color models without paint

Based on reliable, affordable inkjet technology

No physical support structures needed

 

PolyJet inkjet technology works by jetting photopolymer materials in ultra-thin layers (16µ) onto a build tray layer by layer until the part is completed.

Applications:

Electronic components and connectors, electronic packaging

Presentation models, knobs, buttons, fittings, valves

Parts with complex interior features

 

Some good reasons to choose Polyjet:

Visual models with fine details & smooth surfaces

Rubber-like prototypes

Multi-material parts

Masters for copying techniques (vacuum casting)

 

Selective Laser Sintering

Successive powder layers are spread on top of each other. After deposition, a computer-controlled CO2 laser beam selectively binds together the powder particles of the corresponding cross section of the product. During laser exposure, the powder temperature rises above the glass transition point after which adjacent particles flow together.

Applications:

Fully functional prototypes with mechanical properties comparable to those of injection moulded PA12 parts

Series of small components as a cost-effective alternative to injection moulding

Production of unique, complex, personalized designs built as once-only products or in small batches.

 

Some good reasons to choose Laser Sintering:

Durable and functional large and complex parts

Direct production of low volume projects

Design freedom (no support structure necessary)

Wide range of finishing degrees and additionally can be sealed watertight

 

Direct Metal Laser Sintering

The technology fuses metal powder into a solid part by melting it locally using the focused laser beam. Parts are built up additively layer by layer, typically using layers 25 micrometers thick.

Applications:

Manufacturing of organic or highly complex geometries

Tooling inserts featuring cooling channels

Lightweight structures for aerospace and high technology applications

 

Some good reasons to choose DMLS:

DMLS allows for more rigorous testing of prototypes

Direct production of low volume projects

Design freedom (no support structure necessary)

Parts can be design with internal features and passages that could not be cast or otherwise machined.

 

Vacuum casting

The method uses cast silicone molds made as follows: a master model (typically by selective laser sintering) is carefully prepared to ensure a high quality finish to the surface and the definition of the parting planes. Silicone is cast around the master, partially under vacuum in order to avoid air bubbles being trapped in between the master and silicone. After curing, the mold is cut according to the parting planes and the master is removed, leaving a cavity to make copies.

Applications:

Production of small series (10 to 20) of functional plastic prototypes

Parts are suitable for fit and function testing

Prototypes for mechanical, thermal or aesthetic validation

Marketing purposes

 

Some good reasons to choose Vacuum Casting:

Cost-effective for low volumes

Functional plastic parts

Broad range of materials (rigid & rubber parts)

Multi-material parts via over moulding
