From high load to high temperature: individual parts from 50 iglidur® materials available within 2-5 days

With custom-made 3D-printed injection moulding tools, igus® offers designers a new possibility to produce self-lubricating and maintenance-free parts and small batches. Engineers can now choose from the entire range of 50 iglidur® high-performance plastics, including specialists for high load, food contact, underwater or high temperature applications, with delivery within 5 days of order.

Injection-moulded, 3D-printed or machined from bar stock – the motion plastics specialist igus® offers engineers a wide range of possibilities to obtain their self-lubricating parts, such as gears or plain bearings quickly and cost-effectively. igus® also offers the possibility to solve difficult technical challenges quickly by means of a 3D-printed mould – and now with all tried and tested iglidur® materials.

“Since the production of injection moulds made of steel is comparatively expensive, takes longer and is only feasible in the production of large quantities, special tribo solutions can be produced with a printed mould within 2 to 5 days with up to 80 percent cost savings in production and further, even small quantities can be produced,” says Robert Dumayne, dry-tech® director, igus. “A new process for the production of printed injection moulding tools now allows igus to make even more precise and long-lasting products.”

The material selection of the moulded part determines the material and the manufacturing process of the printed mould. “From an availability of 50 tribologically optimised and online configurable iglidur® materials, designers are free to choose the right material for their special part,” continues Dumayne. “For example, iglidur® G is an all-rounder, whereas iglidur® X is for long-term application temperatures of up to 250°C.”

Depending on the material chosen for injection moulding, the mould is either SLA or SLS printed and then used immediately in the injection-moulding machine. Thus, parts are ready for shipment within a few days. The material structure of the printed injection mould ensures that it can withstand the high temperatures during injection moulding, which means that one mould can produce prototypes and small batches up to 500 pieces cost-effectively and quickly.

“The production of special tribo-parts by means of printed injection moulding tools is particularly advantageous if the desired material cannot be processed in the 3D printer or when the parts are used for a test that is intended to simulate as close as possible conditions for a later mass production,” explains Dumayne. “We have moulded over 2,000 moving parts already, using printed injection moulding tools.”

Find the right bearing fit with new igus® Fit Calculator app

igus® Fit Calculator is a new app for iOS and Android that enables engineers to calculate dimensions and tolerances for bearings according to ISO 286. The app, which can be easily found and downloaded from the smartphone’s or tablet’s app store, is very simple to use and requires no registration.

By selecting the nominal bearing size (between 0.01 and 500mm) and required tolerance grades for the housing bore and shaft, the igus® Fit Calculator app calculates the dimensions and tolerances instantly. The maximum and minimum dimensions and the associated type of fit (clearance or interference fit) are also provided.

A key benefit of this streamlined app is that it can be used offline, which is particularly useful when working in closed machine or safety zones. In addition, users can swap the units at any time between metric and imperial systems.

Detailed help regarding the calculations of the tolerance field is provided, as well as direct contact with an igus bearing specialist. For more information, please visit: www.igus.co.uk or call igus directly on 01604 677240.

The 3D printed house

imageuk123 A house made by a 3D printer is no longer just a dream. Did you know the ‘Europa-Haus’ in the Amsterdam Marine Quarter, built for the duration of the Dutch Presidency of the EU, was partly constructed in this way?

Based in Amsterdam, DUS Architects realised the idea of building entire houses in this way could be done with a mobile 3D printer in extra-extra-large (XXL) format. For the construction of the building, the architects worked closely with igus.

It might seem a little far fetched at first glance, but on closer inspection, the building is not only appealing, but has many other benefits. The load-bearing structures are manufactured from biodegradable plastic, which are recyclable. This makes the structure both eco-friendly and sustainable. Also, some of the interior decorations were also 3D printed.

The architects were keen to point out that while pre-fabricated architecture is cost-effective, it can restrict creative design freedom. The structural elements of the façade were 3D-printed, and then concreted into position on-site. This process of construction can also work very well to build new homes in disaster areas.

To transform this idea into reality, DUS Architects founded a separate company called Actual; this enabled the owner to design or select components on a digital platform, which are then manufactured on site using mobile 3D printers.

The first generation 3D printer had a separate room for the control, this limited the part size to a maximum 2.50 x 2.50 x 3.50 metres. There was also need for improvement, both in precision and in the printing speed. So we optimised the design of the mobile 3D printer and developed a linear robot for the print head.

During the planning stages, the engineers used the modular drylin system multi-axis linear robots. They are available as line, flat and room gantries for one, two and three axes, and depart from pre-defined surfaces and spaces. To enable the print head to move precisely, self-lubricated drylin toothed belt units were used. The leadscrew units were used to position the gantry vertically, which integrate drives that provide position detection.

The engineers also supported Actual with integration of the printer, which can now print structural elements of up to 6.50 m. In addition to the linear robots, other parts from igus were included in the construction of the 3D printer, including plain bearings, cable management systems and linear systems.Joe Platt, Head of Mechanical Engineering at Actual, said of the project: “igus gave us excellent support, and the gantry proved to be the best in practice.”

Among the projects being undertaken by Actual at present is the “3D print Canal House”, which is currently being built on a town canal in Amsterdam. The construction site is public and has more than 1,000 registered visitors per month.
