I see that someone setup the Sinterit Lisa in 3D Fab. Has anyone printed with it yet, reading the manual it seems pretty straight forward yet extremely messy.
Any clue on material costs?
I watched the intro video for it on Youtube, and they’re wearing PPE masks. Is that something we will need to use in 3D lab when this beastie is in use?
Looking at the video below, I’d say yes it is messy, mask probably smart. Question is: what about people in room? If it gets airborne then everyone else exposed. May need small hood around it when working with powder if it is exposing people. Hope not.
Is there an MSDS sheet on material? Don’t know name of material but will look. May not be required, but MSDS says to then that must be addressed and decided upon.
Looks like a cool device.

Looks like the majority of choices are Nylon based.
I couldn’t access Sinterit to get their material info
Neither could I. It’s probably not the material as much as particle size that gets into air. Trying to find where material is sold so can look it up.

Doesn’t seem like immediate risk. Found MSDS sheet for material sold for this printer. MSDS_PA_650.pdf

It’s still being worked on, we need an air drop in 3dfab for it.
There’s a line that runs over the room we can tap into that goes into electronics

If you need it, take it. I don’t see the ELab needing air any time soon. Should the need arise, we’ll deal with tapping it at that time. Think there’s a pressure regulator on the end of the line.

Found it through 3rd party sellers. I keep getting the “No one’s here” error message.
I viewed their site in the Wayback Machine and found a US Distributor (from May 2017):

I got my MSDS from a Texas vendor. site.
Thanks @Lampy. Watched some of the videos. Here is some information on the PA12:
EC SAFETY DATA SHEET PA12

MATERIAL DATA SHEET

The link below states “it is recommended to use the PA12 material for the first printing as it optimally seals the printing chamber”. I am assuming this is the bottles which are included.
I had heard that the powder was only one time use by people at DMS, but it seems they suggest that the unused powder can be recycled and used again.
As the powder is particle size 100 micron to 20 micron, I’m guessing the screen needs to be tight enough to just not let particles larger than 100 micron through. This would be a screen mesh of 140 mesh or higher.
In Pyro, @Lampy and I have found Bucket Screens to be the best option for this kind of work.
http://www.bucketscreen.com/BucketScreens.htm
They use the nesting design of the 5 gallon buck to make a solid fit. Plus, the manufacturer guarantees the screen will not pull out. In fact, if the screen pulls out, they ask you to send it in so they and understand what failed and they will replace the screen. This style screen really keeps the dust produced very low as it is contained in the 5 gallon bucket rather than floating out into the room. In pyro we really work these screens hard and they last.
One note, we will have to ask to have a custom screen made for use as the standards mesh only goes to 100, and we will need a 140 mesh screen. This isn’t a problem, they commonly do custom meshes or material as needed, you just have to contact them.

Yeah from what i’ve seen, it is reusable after being sifted
The powder is reusable and long as it passes through the screen. Plus you add the right amount of new powder to make up the volume.
The PA powder says 30% renewal rate is the target.
Sinterit supplied gloves and masks, we don’t need to buy anything. There is a manual sieve for powder reclamation, but not the automated device that Sinterit sells.
The printer is set up on a base that @PearceDunlap welded up for us. Thanks, Pearce! You access the build area from the top of the printer, so it had to be set low.
We need an air line for the sand blaster for cleaning the prints.
I started to try a test print with a small TIE Fighter model that I’ve printed on a PolyPrinter. It has a lot of fine details that would be a good test of the SLS technology. However, the estimated time for the print (<2.5 cm model volume) was over 5 hours. That included 1 hour 14 minutes of warm-up time and 1 hour 43 minutes of cool-down time. I don’t have that much time to spend at the 'Space today, so I’ll have to run it later.
Another concern I have is that this printer is going to require A LOT of cleaning. The manufacturer recommends that the lenses and lase protective glass be cleaned after every third print. The laser protective glass has to be removed from the lid to be cleaned. Also there is an area below the build plate that has to be cleaned every third print as well.
The Sinterit Studio software is installed on the left computer, as you face the windows. Thanks @StanSimmons for assisting with that. The manual for the software talks about a way to updated it, but the menu option is not in the version that we have. Also, the setting for the Flexa Black materiel is NOT in the software. I don’t know how we go about getting updated software.
I haven’t given up, but I wanted to get my findings so far documented.
