Overview: Sinterit Lisa Pro, industrial desktop SLS 3D printing

certification

In Might 2018, Polish 3D printer maker Sinterit returned with the Lisa Pro SLS method. The most current evolution from the first Lisa 3D printer, the Pro is engineered for industrial excellent output on the benchtop.

By invitation to Sinterit’s test facility in Krakow, 3D Printing certification Field spent a few times mastering about the new Lisa Pro, and placing the equipment to the check.

Industrial SLS on the benchtop

While primarily designed with the exact same industrial style and design framework as its predecessor, the Lisa, the Lisa Pro has obtained three major updates that will be taken into thing to consider in this critique.

First of all, the Lisa Professional has been further more functionalized by adding optional inert nitrogen gas management to the create chamber. With this addition, Sinterit can expand on its assortment of desktop all set SLS materials into a wider selection of far more industrial-grade powders.

Secondly, overcoming one of the most tough aspects of SLS 3D printing certification, the Lisa Professional has a larger develop volume: the print mattress actions 150 x 200 x 260 mm (X x Y x Z) making a build volume of 316mm. The Lisa 1, for comparison, is 150 x 200 x 150 (X x Y x Z) with a quantity of 245 mm.

And thirdly, as components updates would be incomplete with out software program advancements, the Lisa Professional arrives with a quantity of under-the hood enhancements, boosting the abilities of equally procedure computer software and 3D printer firmware.

Very first impressions and elements

On to start with effect, the Lisa Professional seems effectively created to industrial criteria, and provides a quantity of eye-catching structure characteristics, this kind of as the entrance panelling, and an in-built 7 inch touchscreen. It has a sturdy, strong make, which helps supply reduced vibration, precise actions and dimensional accuracy.

It is considerably greater in sizing in contrast to the authentic Sinterit Lisa and fundamentally most of the hardware features are carried over from the earlier structure: the X,Y gantry, print bed design, supply bed, recoater, reflectors and protective glass. The belt has a new style, and nitrogen input is basic, labelled obviously on the still left hand facet. We were also assured that, on release, all appropriate documentation for nitrogen tank attachment would be packaged together with the Lisa Professional.

At present, the corporation has built 7 components: PA12 Smooth, PA11 ONYX, FLEXA BLACK, FLEXA Gray, FLEXA Dazzling, FLEXA Gentle and TPE, with more to come in the close to long term. A selection of these supplies ended up shown all through  the Lisa Professional exam day, but PA11 ONYX was made use of for this assessment.

An interesting application package is also offered for several institutions. With this offer four different temperature options can be controlled, allowing for universities and businesses to experiment with their individual materials on the Sinterit Lisa Pro.

Sinterit Studio 2019 and setup

Sinterit Studio 2019 beta software program was employed in the course of the test of the Lisa Pro.Although slicing velocity was somewhat slower in this pre-marketplace section, there was a marked advancement in the person expertise and the in general aesthetics of the plan. The entire slicing expertise is move centered to make it helpful to both equally new and knowledgeable end users and specialists alike. In the application, diverse infill designs are also proposed to the maker, in get to lower the printing time and maximize performance.

Once we organized our examination file, an electronic housing circumstance, Sinterit Studio 2019 calculated the approximated print time. In addition, the system communicated how considerably powder was necessary for the print, along with the fresh powder excess weight to be additional to the supply for to mixing. This attribute is a welcome improve, as just before ratios would have had to be manually calculated before printing.

From below, we moved to the touchscreen. Updates to the firmware in the device intention to eliminate the hazard of user mistake from set up right until aspect removing. All in all, we uncovered the software package/firmware mixture intuitive to use. The powder content, glass cleaning and oiling were being all carried out under advice of the in designed software program which was greatly useful – anything we can attest to in the early models of the Sinterit Lisa also.

Just after machine planning, we transferred the electronics housing take a look at file to the 3D printer via USB and the process began.

The finish solution

Right after leaving the Lisa Pro to print overnight (the work took all over 11 hrs whole), we returned the subsequent morning to process and end our sections.

Applying instruments supplied alongside the 3D printer, we were in a position to speedily remove the the greater part of the powder cake. The compacted powder chunks were then established it apart for sieving, utilizing the Sinterit Sieve, and recycling in a fresh print.

To remove the finer, more “sticky” powder particles of our item, we have been then essential to manually sand blast the casing in a separate auxiliary unit.
