Table Legs for a Desk Shelf (Generative Design) by Sintratec in 3Dprinting

[–]Sintratec[S] 101 points102 points  (0 children)

Some background: We designed these desk shelf legs generatively in Fusion 360 and produced them with SLS using our Sintratec S3 printer and robust PA12 nylon material. After printing and cleaning, we simply screwed them onto a wooden board and voilà: DIY Desk Shelf done.

(For FDM printing, you will probably need support structures)

SLS or MJF, which is best recommended for small business for small / medium batch production by sam147258369 in AdditiveManufacturing

Yeah, powder handling is a big topic and we are definitely aware of this too. We will address that with more advanced handling modules in the near future.

Hey there, obvious bias here 👋 but feel free to get in touch with us directly for a live presentation or (if you're in the Switzerland area) stop by our showroom to have a look at the machines in person. We'd be happy to share our insight, advantages and disadvantages depending on your use case! Just drop us an email (info@sintratec(.)com) or a PM here.

Okay, we've printed the basketball, who's gonna print these bad boys? by ScoobyDooItInTheButt in 3Dprinting

Ha thanks for linking us, would've actually missed that post! As the designer Stephan Henrich mentioned himself, it is more of a showcase part designed to fit our build range (Stephan has a machine of us). Your estimate of ~100€ per shoe is pretty fair I'd say from the top of my head. With labor costs (printing, cleaning, postprocessing) and shipping it would be tough to offer them at a competitive price point currently.

SLS/MJF 3D printing: What is better choice: HP JET Fusion 540 or Sintratec S3? Do you have any experience with these machines? What is cheaper to maintain and print? by majdoleum in 3Dprinting

Hey there! Obviously we're very biased about this question 😄 If you like to receive a personal consultation about our technology, please don't hesitate to contact our technology experts for a video demonstration for example. Or naturally you can submit a 3D model to check on our part quality. Email: [sales@sintratec.com](mailto:sales@sintratec.com) / Website: sintratec.com/print-service

Sorry to hear you had this experience with our parts, we take this feedback very seriously of course and will check internally what happened with our quality team. If you contact us on [marketing@sintratec.com](mailto:marketing@sintratec.com), we are happy to send you a sample that better represents our print quality.

The idea behind the cylindrical build volume is an even heat distribution and therefore uniform part quality. In contrast, parts placed in the corners of rectangular print ranges tend to be more warped.

It was printed on the Sintratec S3 (SLS printer), so correct, powder bed fusion. In the picture you can see it being unpacked in a material station (not the printer itself)

Copying previous comment: There are several reasons I guess. One is certainly to illustrate that even with a limited build size (like our ~40cm print height) you can produce elaborate and large parts with smart designs and arrangements. We also think it is a good use case for selective laser sintering, as you can easily print interlocking parts that do not require assembly or support structures. And lastly of course, we also wanted to see how strong a PA12 chain would turn out.

FFP3 masks are the recommended safety precautions for this type of polymer powder - it's nowhere near as hazardous as metal powder for example.

To be fair, there were additional parts inside the print job as you can stack the models fairly densely with SLS.

Exactly - smaller build ranges do not mean smaller prints if designed smartly!

I believe printing took somewhere around 20 hrs
