Introducing The PRUSA PRO HT90 - The Best Desktop Printer for Engineers

In this video I talk to Vojtech Tambor, CEO and founder of Trilabs, and the man in charge of developing the PRUSA PRO HT90. He clearly knows his stuff when it comes to filaments and printing parameters, and has applied his knowledge to developing an awesome printer for scientists and engineers.

There are a lot of little bits of information here - I learned a lot just from our short conversation, about applications of various polymers, and tons of hidden details in the HT90 design. I hope you enjoy this interview as much as I did, and click the button below if you want to pick up an HT90 for your engineering department.

Video Summary

At the Prusa Research booth, VOA introduced the HT90, a high-temperature 3D printer designed for printing advanced materials. This innovative machine boasts a chamber temperature capability ranging from 60°C to 90°C, enabling users to process a wider range of polymers at higher temperatures, resulting in stronger and more detailed prints.

The HT90 stands out in the market due to its ability to handle complex geometries and advanced materials like nylon, ABS, PC, and ASA. This printer is ideal for users looking to create prototypes requiring specific material properties beyond common options like PLA or PETG.

Engineering materials play a crucial role in the additive manufacturing process and are a significant advantage of having the capability to print various materials. While industries like automotive, such as Volkswagen, traditionally use materials like ABS for their applications, there is a growing acceptance of other materials like PLA due to its affordability and ease of use for rapid prototyping.

The choice of material ultimately depends on the project requirements, whether for shape validation, temperature resistance, mechanical properties, or other specific needs. For instance, using materials like pure nylon can be advantageous for applications requiring lubricity or friction resistance. Gradually validating components through stepwise testing ensures that the final product meets all necessary criteria, from shape accuracy to material properties, demonstrating the flexibility and utility of additive manufacturing technologies.
