With its latest production process - additive manufacturing, commonly known as 3D printing - Murtfeldt Kunststoffe uses the FDM procedure (fused deposition modelling). This involves unwinding the model material - wire - from coils and applying it layer by layer through fusion to create the required component.
 After an intensive test phase, Murtfeldt now has profound knowledge of this field and is offering the manufacture of professional 3D-printed components for resilient prototypes, small series, and functional models.

The benefits of 3D printing

The additive manufacturing solution of 3D printing has a range of advantages compared with machining, casting, or extruding.

 

 

Today, the collective term "3D printing" represents a set of additive manufacturing technologies that work in accordance with different principles and are each suitable for extremely specific materials only. Their common denominator: During 3D printing, a three-dimensional object is created through the layering of material. 

The benefits of 3D printing do not only lie in the production of cost-effective prototypes, fast availability, and low planning costs; in addition, material efficiency is significantly higher in comparison with shape cutting. Furthermore, extremely complex components with hollows, ducts, and varying wall thicknesses can be produced, since the components basically consist of stacked 2D layers. 

The prerequisite for the realization of prototypes and components of this kind from plastic is three-dimensional CAD data that can be implemented malleably by a 3D printer. If the customer does not have this kind of data, the Murtfeldt team of application engineers and technicians can naturally create this data in accordance with the specifications of the customer.

Example usage areas

  • Prototypes
  • Functional models
  • Small series
Murtfeld plastics now also is able to use 3D printing for the production of components, resilient prototypes, small series, and functional models.
Murprint® wurde vom Dortmunder Unternehmen Murtfeldt speziell für den industriellen 3D-Druck entwickelt.

We print with Murprint®

This innovative Murtfeldt plastic ensures top, lasting results.

The machines and techniques used in 3D printing in the plastics sector and FDM systems have been significantly further developed. Fused deposition modelling (FDM) can be used to process a lot of material that becomes soft and malleable when heated, e.g. thermoplastics such as ABS, PC, and PA. The print head of FDM machines consists of a hot nozzle into which the solid raw material is pressed, turning it into liquid. It exits the other end of the nozzle as thin, soft strands. The print head uses this to draw a layer of the required object. 

As a manufacturer of innovative plastics, Murtfeldt provides a selection of high-quality materials that are suitable for the requirements of this process in the form of the plastics in its Murprint® product range. Some of these are also available in different colours. Whether your main requirement is cost, durability, or a combination of these, we will always use the most suitable plastic in accordance with your needs. 

Naturally, other materials are available as well as Murprint®. It's worthwhile asking!



Incidentally, soluble support materials are used when processing the Murprint® materials.

3D printing service: Planning and preparation

The Murtfeldt Kunststoffe team supports you in planning and designing the CAD data required for 3D printing.

 

 

The manufacturing of custom components using a 3D printer conceals a comprehension issue related to the word "printing". It implies the following: "I press a button and my model comes out of the printer ready-made." But unfortunately, it's not actually that simple. Precisely formulated, three-dimensional CAD data is absolutely vital for the realization of prototypes or functional models. 

If you do not have any data of this kind, Murtfeldt can help you to overcome this technical obstacle. Not only do we possess powerful application technology, we also have specially trained CAD technicians who - as well as developing 3D CAD models - are also able to assess, adjust, and optimize them in order to get the best possible results on the 3D printer.

3D printing service: Finishing

The finishing of printed components or prototypes can be included in the production process in an on-the-fly manner if required.

 

 

In principle, all prototypes, functional models, and components that are produced by Murtfeldt using 3D printing are ready for use. However, thanks to the facilities available at the company's premises, various technologies can be used after the actual printing process in order to finish or further process components to optimize the results even further in accordance with your requirements and to further improve the quality. Our team will be happy to discuss the possibilities and their advantages and benefits with you.

The following finishing options are available at Murtfeldt:

  • Deburring
  • Blasting
  • Gluing
  • Filling
  • Grinding
  • Printing

From the concept to the model - simply using 3D printing

Interview with Andy Middleton (Stratasys) on 3D printing. 

 

3D printing can be used to create design models as well as enduring series components. The specialist magazine "konstruktionspraxis" asked Andy Middleton, President EMEA at Stratasys, about the possibilities that this offers to design engineers.

What technologies does Stratasys offer for the additive manufacturing of plastic parts?

The Stratasys portfolio includes fused deposition modelling (FDM) and PolyJet. Our offering ranges from cost-effective rapid prototyping devices for desks to large production systems. Both technologies have their advantages and disadvantages. The decision as to which technology should be chosen ultimately depends on the purpose of the component. If you require industry-leading attention to detail for extremely delicate components, PolyJet should be your first choice. However, if you are interested in durability and using components in extreme conditions, FDM is the best solution.

Which product properties and functions can now be modelled using the PolyJet procedure?

Our PolyJet 3D printers can print ultra-fine layers with a thickness of 16 micrometres, which corresponds to the highest print resolution currently available on the market. They enable the creation of really fine, detailed models with a smooth surface. Our soluble support material enables the construction of complex structures that would be impossible using traditional manufacturing processes. For example, dental and orthodontic laboratories can use our 3D printers to design, print, and clean extremely detailed dental models within just a few hours.


With our multi-material 3D printers, which combine various different materials, users can quickly turn their vision into reality using a functional, 3D-printed model. This is not just restricted to engineering and production; for example, additive manufacturing also allows surgeons to prevent risks they had not foreseen by, for example, trying out operations on 3D-printed models of the relevant body part before actually operating on the patient. Hospitals can convert MRT scans of patients into 3D-printed models. This enables them to detect problematic areas more easily without having to take X-ray images, as was previously the case.

Which model materials are available for this?

Stratasys offers solid materials, rubbery materials, opaque, transparent, and biocompatible materials, dental materials, and technical plastics (for these, two base materials are mixed to obtain a third material with properties that precisely match the requirements for the prototype - this is unique in the sector). We also have Digital ABS, which - with its combination of temperature resistance and resilience - aims to simulate standard ABS plastics for functional prototypes and production tools.

With this ABS-like material, you can also print tool moulds for die casting. What are the advantages of this?

Our customers in the casting sector are increasingly using the material Digital ABS to produce injection moulds. This is because this material is able to withstand high temperatures and constant stresses. Apart from the benefits of high impact resistance and vibration damping, these customers enjoy a range of financial advantages through using our material. Since functional tests and consumer tests can be carried out just a few minutes after 3D printing, significant time and tool cost savings can be made. Furthermore, our customers can implement design revisions within just a few hours and can then produce prototype components in the final material.

What contribution can FDM technology make with regard to lightweight construction?

Users of additive manufacturing in the motor sports sector benefit from reduced lead times and lower costs. In addition, the use of FDM thermoplastics enables the development of resilient, high-performance 3D-printed components in small series for diverse applications in motor sports. These range from functional prototypes to the creation of production tools and include endless design possibilities for 3D-printed production parts for the immediate motor sport environment. In the aeronautics and astronautics sector, too, a range of aircraft manufacturers have switched to using our additive manufacturing technology to produce lightweight components as part of their efforts to replace heavy metal components.

In future, Stratasys wants to work with PTC. What's the aim, here?

As part of our current collaboration with PTC, we are aiming towards providing designers and manufacturers with easier access to additive manufacturing and enabling them to exploit the full potential of the technology. This potential includes unlimited geometries and part functionality, the creation of cost-effective small series, production on request, and the manufacturing of custom products.

What hurdles do designers and design engineers still have to overcome with regard to 3D printing?

At present, designers and manufacturers of 3D-printed components generally still have to rely on other tools in addition to 3D CAD software in order to carry out the design, optimization, and inspection work steps. In many cases, the laborious, inefficient, and frequently interrupted workflow impedes the precise manufacturing of products. This can result in additional work steps and increased time and resource expenditure.

How can this process be simplified?

In our efforts to create a seamless process, we have also introduced PTC Creo 3.0. This simplifies 3D printing and allows users to make fundamental design adjustments, file preparations, print optimizations, and 3D prints with Stratasys 3D printing solutions from the PTC Creo environment.
