The Summit of Additive Engineering
When operating environments exceed 150 °C or involve exposure to harsh corrosive chemicals like sulfuric acid, hydrogen sulfide, or jet fuel, standard engineering plastics like PETG and Nylon disintegrate. Enter the PAEK polymer family, led by Polyetheretherketone (PEEK) and Polyetherimide (Ultem / PEI).
These ultra-polymers offer tensile strengths over 100 MPa, continuous operating temperatures exceeding 250 °C, and chemical resistance comparable to surgical stainless steel.
Replacing Titanium and Machined Metals
In aerospace and downhole energy exploration, weight savings translate directly into fuel efficiency and operational payload capacity. PEEK has a density of only 1.30 g/cm3 compared to 4.5 g/cm3 for titanium and 2.7 g/cm3 for aluminum, delivering up to 60% mass reduction while maintaining structural integrity under vibration.
Industrial Printing Requirements
Printing PEEK is impossible on consumer 3D printers. It requires specialized high-temperature additive chambers:
- Nozzle Temperature: 400 °C to 450 °C to melt the semi-crystalline matrix.
- Actively Heated Chamber: 120 °C to 150 °C to control crystallization rates and prevent catastrophic layer delamination.
- Thermal Annealing: Post-print ramped thermal conditioning in nitrogen-purged ovens to achieve 35% crystalline density.
At FamilyMake, we partner with specialized industrial teams to prototype and evaluate high-performance polymer components for demanding field deployments.
