Delrin is often chosen in many engineering applications due to its characteristics such as high durability, wear resistance, and low friction coefficient.

With these features, it can be used in the production of machine parts and gears, and it can also be preferred in the production of sports equipment and prostheses because it can provide durability and lightness at the same time.

There is no 3D printing material that matches all the features of Delrin exactly. However, you can choose materials that offer features close to you according to the following factors:

• Mechanical Properties:
  Polyamide 12 (PA12): It offers high strength along with good chemical resistance and low friction coefficient. It is a close alternative to Delrin.
  PEEK: Stands out with its high temperature resistance, good chemical resistance, and wear resistance features. However, it is more expensive than PA12.
  PC (Polycarbonate): PC, which offers high strength, good chemical resistance, and impact resistance, can be an alternative to Delrin in some cases. However, it is not as slippery as Delrin.
  ABS (Acrylonitrile Butadiene Styrene): Although it is less durable compared to Delrin, it can be preferred for some applications that can be used instead of Delrin with its low friction coefficient and affordable price. It can be especially used in prototyping.

• Price: 3D printing filaments are generally more economical compared to Delrin. However, high-performance filaments can be more expensive than standard PLA filaments.
• Chemical Resistance: It’s important to choose a filament that is resistant to the chemicals used in your project. Xometry Turkey can support you on this issue.
• Surface Quality: You should choose a filament suitable for the surface quality required by your project and keep in mind that the surface outputs of layered manufacturing products will be different compared to CNC processing.
• Application Requirements: Always keep the unique needs of your project in mind and make your choice accordingly.

If you’re looking for that ‘slick’ Delrin feel but want to 3D print it, you should really look into Igus Iglidur i150 or i180. Igus basically makes ‘3D printable Delrin’ by embedding solid lubricants into their filament. For a propeller, i180 is probably better because it’s stiffer than the i150. It has that same low-friction coefficient you’re after and won’t wear down the motor shaft or hub if there’s any vibration. It’s much easier to print than standard delrin filament which, as everyone knows, is a nightmare for bed adhesion

That’s a fair point on the friction specs, but for something like drone props, I’d actually argue that Nylon 12 (PA12) or a Carbon Fiber Nylon (PA-CF) is closer to the functional goal of Delrin than actual delrin filament is.

Don’t get me wrong, Delrin is the gold standard because it’s stiff and slippery, but for flight, it’s just heavy. A PA12-CF filament gives you that same durability and impact resistance but with the extra rigidity you need for thin blades to stop them from fluttering at high RPMs. If you’re still in the prototyping phase, PA12 is definitely the ‘closest material to Delrin’—it’s basically the workhorse of the engineering world and won’t shatter the moment you clip a gate.
