parts are three times more wear-resistant than those printed from standard materials
igus® has expanded its 3D printing material offering further with the introduction of a material suitable for Selective Laser Sintering (SLS). With the familiar wear resistance of the four already available tribo-filaments for Fused Deposition Modelling (FDM), the new iglidur® I3-PL tribo-powder is for printing special 3D parts using the SLS technique.
In the igus® test laboratory, plain bearings made from the new material have been compared with those printed from conventional SLS materials. After pivoting, rotating and linear testing, initial results indicate that the iglidur® I3-PL parts are at least three times more wear resistant.
“Selective laser sintering produces a 3D part with better precision, compared to parts printed using the FDM technique,” explains Robert Dumayne, director at igus®. “Another advantage of the new iglidur® I3-PL material is that the parts can achieve a much higher strength due to the pressure in the SLS method.”
An additional benefit of using the laser sintering is that no support structures are needed. This is because the loose powder, which is not melted by the laser, acts as the supporting material. Thus less finishing work is required on the components and the parts can be used directly.
igus® introduces a new plain bearing material developed specifically for medical and laboratory applications. Called iglidur® AB, the material has undergone rigorous antimicrobial efficacy testing, which is the measurement of antibacterial activity on plastics and other non-porous surfaces, according to the ISO 22196: 2011 standard. Results show that its antibacterial properties will help reduce bacterial contamination to users and patients and, like all other iglidur materials, is self-lubricating and therefore maintenance-free.
“From pick & place equipment in the laboratory to mechanical joints on patient furniture, the areas of application for this new material are diverse,” says Robert Dumayne, director, igus®. “As well as its antibacterial properties, iglidur® AB brings two further advantages to the medical and laboratory industry – there is no risk of contamination by oil or grease and machinery and equipment can be cleaned safely, without the risk of washing away lubricants.”
iglidur® AB offers good resistance to chemicals, which enables bearings made of this material to withstand aggressive cleaning agents. In addition, a continuous application temperature range of -40 to +70ºC is possible.
Many igus materials can be used within bikes, one of these being iglidur.

A state-of-the-art sport has hit the scene, free-style kite land boarding, using wind to provide the motive power and lift using a power kite with mountain board (similar to a skate board). Competition within this field has developed leading onto the integration of tricks and risky manoeuvres. Technology of the kites and boards has therefore also progressed to complement these tough conditions, and with the pressures on safety and performance steadily increasing, riders are constantly looking to source strong, light weight components.
Yannick Schwicket (German Pro Team Rider) demonstrates how the boards are tested:

Custom Kite Boards have found that igus bearings are a great fit for the needs of this specialised market. Their bespoke boards use Prepreg carbon fibre in the construction of the deck. Paul Hartland, founder of CKB, explains how igus products have been used. ‘I am always searching for alternative innovative products to use in components. iglidur Z bearings, from igus, were used initially within an early prototype to give overall weight reduction and reduce wear in muddy and sandy conditions. The bearings withstood the use of various riders within the challenging environments.’
Custom Kite Board are now testing igus spherical bearings which are set to replace the pivot cup in conventional skate board type truck axle plates. The pivot cup is traditionally a simple polyurethane structure, which due to continual friction between the pivot arm and cup, wears out swiftly. Frequent replacement is inevitable and necessary otherwise instability (speed wobble) occurs due to slack as well as eventual wear occurring on the pivot arm resulting in damage to the truck axle.
The dry-running, weather resistant, lubrication-free properties of the igus bearing is a perfect solution. Sliding surfaces are transferred to the spherical bearing without the need for lubrication. As a result, the overall life of the board is increased, maintenance and incurred costs are reduced and truck axle steering ability is improved. If required, the bearing can still be replaced with ease via 2 bolts and lock-nuts.
iglidur can be used in hydraulic cylinders for very large loads.
The advantages of using this include:
- Maintenance free properties
- Can take a very large load
- Non corrosive/ chemically resistant
