the most economical per print in compact SLS offers sustainable printing without any powder waste when used as intended utilized in medical and dental applications manufacturing of electrical and electronic components It is the ratio of a minimum amount of fresh powder needed in a mixture of material used in an SLS 3D printer. A lower refresh ratio means better cost-efficiency of the material. The amount of needed fresh powder is automatically calculated by our software and shown on the printer screen after the print job is finished. Just add shown amount of material into the mixing cycle of used material and you can start your next job with refreshed material To start SLS 3D printing you need the powder starter pack. After that, you’ll only need to refresh the powder you own with fresh powder. We have received the Suzy for printing and started it up with PA 11.5. The first prints turned out really well. But what’s huge is we reduced printing time for a full build space by more than fifty percent. Thank you very much for convincing me to make the switch from PA12. I believe that we will be able to quickly implement a new product line with PA11.5 by the end of the year. Sinterit’s Lisa X has allowed us to reduce lead-times and create better solutions — faster, helping us satisfy our customers. We have looked at other 3D printing methods, and other brands, but ultimately decided on SLS and chose Sinterit for their communication, and open material possibility. Something we couldn’t find in other suppliers of affordable entry level SLS printers. Getting Lisa X solved a lot of our problems. It has a big enough printing area, so we almost always can print big components in one part. It wouldn’t be possible with competitive SLS 3D printing solutions. The main reason Somfy reached out for the SLS technology from Sinterit was productivity. Printing many pieces in one batch was a game-changer When we look at Lisa’s line of printers, or Sinterit at general compared to other companies, the two major things that we liked were the materials, that are open source, so we are not locked into one brand […]. We are able to look around the market and use a material that works best for the part. PBT Optimal is a Polybutylene Terephthalate (PBT) powder designed for SLS 3D printing with the Lisa X. It offers high rigidity, great detailing, excellent chemical resistance, and very low cost per part, making it ideal for cost-conscious applications. PBT Optimal is engineered for cost-effective prototyping and production. It features: – The lowest printing cost per part among Sinterit’s compact SLS materials – Low refresh ratio (20%), meaning minimal waste and reduced material usage – Excellent stiffness and fine detail resolution, ideal for precision components PBT Optimal is specifically optimized for use with the Sinterit Lisa X SLS 3D printer. No, nitrogen is not required when printing with PBT Optimal. PBT Optimal is suited for a wide range of technical and industrial applications, including: – thermoforming molds – electrical and electronic components – electronic enclosures – dental applications – prototyping and rigid tooling components – Tensile strength: ~49 MPa – Tensile modulus: ~2700 MPa – Flexural strength: ~50 MPa – Impact resistance (Charpy unnotched): up to 11.12 kJ/m² – Shore hardness: 77D These figures indicate high stiffness, moderate impact strength, and excellent dimensional stability PBT Optimal performs reliably under moderate heat: – Melting temperature: 172 °C – Heat deflection temperature (HDT A): 52 °C – Softening point (Vicat A50): 93.2 °C These values make it suitable for applications involving moderate thermal stress Yes — when used as intended with a 20% refresh ratio, PBT Optimal allows for sustainable printing with no powder waste, making it an environmentally and economically responsible choice. – Color: Dark Charcoal – Mean particle size (D50): 57 µm This ensures consistent surface quality and high printing resolution Need a 3D Printer tailored for this purpose?
