Sinterit Introduces Dedicated Powder Tools for Cleaner SLS 3D Printing

Share this Article

Poland-based SLS 3D printing solutions provider Sinterit, like so many others in the additive manufacturing industry, joined the fight against COVID-19 this year, using its Lisa Pro systems to produce 4,000 face shield adapters that are fixed to off-the-shelf safety glasses. But that’s not all the company has been focused on during the pandemic: in June, Sinterit released a new software update that makes its Lisa and Lisa Pro 3D printers compliant with the Industry 4.0 standard, and launched a new 3D printing center mere months ago, to help drive adoption of low-cost SLS technology. Now, Sinterit has announced the release of its Dedicated Powder Tools, meant to help ensure better powder management.

“With this comprehensive set of powder tools, you will save both time and powder, while keeping your workspace nice and tidy. Since now, your on-print preparation could be twice as fast,” the website states.

“New powder tools cover the whole printing process, from the initial startup, through taking out the printouts, postprocessing, and cleaning, both the printouts and workspace. With the service kit, you get a 360° SLS printing experience. Now there is all you need to act professionally.”

The R&D team at Sinterit has been very busy, working to complete a variety of projects that should improve the user experience for its Lisa and Lisa Pro printers, and one of those projects was the Dedicated Powder Tools set, which helps users prepare their powder prints at twice the speed.

“Unforeseen to anyone, metal additive manufacturing technology finds itself at a critical junction in 2020 in the midst of the supply chain disruption and manufacturing downturn brought on (or at least intensified) by the COVID-19 global pandemic. In a way, it feels a bit like destiny -metal additive markets have been undergoing significant growing pains the last year, and the arrival of shutdowns, shortages, delays, and major economic contractions almost immediately proved the value proposition of additive manufacturing in a very real way,” SmarTech Analysis wrote in its “Additive Manufacturing with Metal Powders 2020” report.

“For many metal AM stakeholders, the challenge at hand is significant, meaning that these next several quarters and years may be the difference between life and death for the crowded metal additive market.”

With that in mind, anything that metal AM solutions providers can do to set themselves apart from the rest of the herd, such as offering this Dedicated Powder Tools set, will help them stake a claim in the market.

Sinterit designed these tools to keep the powder where it’s supposed to be, likening SLS printing to having a dish of food, and the tools as the utensils we use to eat.

“Of course, you can eat with your bare hands, to feel the taste, but you will need to clean a lot, afterward,” the company states on its website.

Keeping things clean starts with the Powder Funnel, which makes it possible to fill Sinterit’s SLS printers without spraying powder in the air. The new funnel is compatible with the Sinterit Sieve, as well as with the Powder Separator that’s used with the ATEX Vacuum Cleaner, and easily attaches to the plastic bottles that hold the powder. Speaking of these, Sinterit used to sell powder in 2 kg bottles, but for users who require more, the new metal container is three times bigger, which means that it is able to hold 6 kg of powder.

The new funnel, along with the redesigned Sinterit Trowel for tamping, definitely make it easier to fill the Lisa and Lisa Pro, but the IO Box increases the powder management by keeping things more precise. It’s a set of two metal elements that fit together to act as guides for cleaner powder pouring, so other parts of the system, like the pyrometers, don’t get dirty. The device performs two functions: filling the printer with powder, and quickly removing the printout, then safely moving it to the post-processing area. If you flip either part upside down, it fits the feed bed to a T so all of the mechanical elements and pyrometers are secured, and guides the powder into the bed.

However, the Sinterit R&D team recognized that most of its 3D printer users may not have a space that’s dedicated for initial post-processing, which is why it created the lightweight Foldable Tray. Any powder that remains after you’ve moved the print into the sandblaster is kept neatly in place in this portable smart tool, which can be easily stored in your workspace. Once you’re done with it, you can dump the powder out of the tray into a waste bin, or vacuum it up.

Janusz Wroblewski, the Sales Director at Sinterit, said, “If you are using Sinterit Lisa PRO a lot, you will quickly learn how much time you can save by just using a few new powder tools we provide.”

Finally, the tool set also includes a service kit containing all of the maintenance parts you need to keep your SLS printer running for 1,0000 hours, including cotton cloths, silicone oil, cleaning wipes, spare recoater cords, and more.
