► Up to 50 times more abrasion-resistant than regular 3D printing materials
► Special polymers with ESD properties, food conformity, chemicals and heat resistance
► Abrasion-resistant and self-lubricating thanks to integrated solid lubricants
Components manufactured with the laser sintering process can be subsequently smoothed. A surcharge will be applied. The methods available are chemical smoothing and vibratory finishing.
In both cases, the wall must be at least 1mm thick to ensure your component's stability and correct manufacture.
In chemical smoothing, the component is treated with a chemical after 3D printing. This softens and smoothes the rough surface typical of laser sintering components. This also seals the surface.
In tumbling, the component is placed in a container with abrasives after 3D printing, and the movement of the abrasives and the component relative to each other smooths the surface.
As a rule, the surface of components manufactured by laser sintering have scarcely any effect on their sliding properties. Friction smooths the surface after just a few cycles, so additional smoothing is not absolutely necessary.
This friction test compares plain bearing bushes that were laser sintered from ⬛ PA12 and iglidur i3. Besides the fact that the iglidur i3 bearing's coefficient of friction is twice as good as that of PA12 plain bearings, the test shows that the coefficient of friction for non-smoothed iglidur i3 components is much lower after a few hours of use and then evens out at a low level.

Components that were manufactured with laser sintering can be coloured. A surcharge will be applied. Our online 3D printing service allows black to be booked immediately. Other colours are available upon request.
In colouring, dye penetrates about 0.4mm deep into the component, changing the measurements negligibly. The limited penetration depth can be used as a wear indicator. Colouring can reduce wear resistance by up to a factor of 3, depending on the application. The mechanical properties remain almost unchanged. Colouring requires a minimum wall thickness of 1mm to ensure your component's stability and correct manufacturing.
