How do different 3D printing technologies—such as FDM, SLA, and SLS—compare in terms of material properties, print accuracy, production speed, and long-term durability of the manufactured parts?

Ventilator: A Lifesaving Medical Device
A ventilator is a critical medical device designed to support or completely take over a patient’s breathing when they are unable to do so effectively on their own. It works by delivering oxygen-rich air into the lungs and removing carbon dioxide, ensuring that the body’s vital organs receive the oxygen they need to function. Ventilators are commonly used in intensive care units, operating rooms, and emergency settings.
There are two main types of ventilators: invasive and non-invasive. Invasive ventilation involves inserting a tube through the mouth or nose into the trachea, typically used for patients in critical condition or undergoing surgery. Non-invasive ventilation, on the other hand, uses a mask fitted over the nose or mouth to assist breathing, often applied in cases of respiratory distress or chronic conditions like sleep apnea.
Ventilators are essential in treating patients with severe respiratory diseases, such as pneumonia, acute respiratory distress syndrome (ARDS),…

I’ve spent the last few years bouncing between FDM, SLA, and SLS, and each one really shaped how I think about material properties and long-term stability. FDM has always been my go-to when I need something quick and functional—strong enough for prototypes, but the layer lines can hold you back on fine details. SLA feels almost magical with its accuracy and smooth surfaces, though the resins can be a bit sensitive to sunlight over time. SLS impressed me the most for durability and complex geometries, especially when I started printing more elaborate models I’d found on platforms like https://www.gambody.com/. That’s where I realized how different technologies can actually bring out different strengths in the exact same design. For anyone trying to choose a direction, it helps to think about whether precision, strength, or speed matters most for the kind of models you want to create.
