A few days ago, we reported the launch of Ice9 and Ice1 3D printers by Norge Systems, these SLS 3D printers, as proclaimed by Norge Systems – “are the first truly affordable SLS 3D printers for small and medium businesses”. However, as it seems, Norge is not the only contender on the affordable SLS 3D printers, stable.
Sintratec – a Switzerland based company is currently developing a desktop DIY SLS 3D printer, and the forecasted price is almost ½ of the Ice1, which is Norge Systems cheapest model.
What is a SLS 3D Printer?
“Selective Laser Sintering” is one of the oldest 3D printing technology around. It uses laser as the power source to sinter powdered material to create a solid structure. Unlike some other additive manufacturing processes, such as fused deposition modeling (FDM), SLS does not require support structures and can produce parts with fine details.
While there are many desktop 3D printers on the market, most of these printers use a FDM method, not SLS. SLS is often more expensive than FDM machine: a professional SLS 3D printer starts at around 200,000€.
About Sintratec and the Launch:
Sintratec is a Switzerland based company, founded by electrical engineers Joscha Zeltner, Christian Von Burg, and Dominik Solenicki. The Trio have been working on this DIY SLS 3D printer project since 2012.
Sintratec plans to launch a crowdfunding campaign on Indiegogo in October 2014, with a price that everyone can afford: 3,999€ ($5,277) for backers. Their goal is to raise money to ship at least 60 of the SLS 3D printer kits worldwide.
Do they have a DIY SLS 3D Printer Prototype?
Sintratec does have a working DIY SLS 3D printer prototype, up its sleeves. The current prototype, code named –”Bobby”, is built in sturdy aluminium, foam glass and steel and features 130mm cubed print volume. One main feature to keep the cost down is that they use a compact diode laser intead of CO2 laser commonly used in current SLS 3D printers. Sintratec’s prototype DIY SLS 3D printer uses a diode laser (445nm, blue) with an output power of over 2W. To get a good laser spot they use also beam correction optics. The compact diode laser is much cheaper than CO2 laser and pumps solid-state lasers in the visible spectral region for a more safe operation.
