Design Materials is an offline material reference guide trusted by hundreds of Engineers, Architects and Designers all over the World. The App was created to be a personal tool to help me take design decisions during the concept ideation of industrial products, in particular for 3D printing. Due to high demand, I decided to make it public and share it's information and power. Basically, it provides the fundamentals for most design/engineer materials on the market, based on reliable and curated academic sources. In addition, you can now create and manager your own Material, Resin or Filament data. Finally, the App features Apple Intelligence (AI) with a pair of Entity Masters in material engineering and STEM: HAL 9000 and Elemento, which can be accessed 24/7 while being on or offline (no internet). The guide contains material categories such as polymers, metals, naturals and more. All of these include synthetic, organic, bio-degradable, plastic, and much more subcategories. Each material contains information such as: About, Properties, Tags, Applications, Types and Photos. HAL 9000 & Elemento (AI entities): The legend of HAL is back. Ask anything from space to robotics or biology, HAL and Elemento are Gods of material engineering and science. HAL does precise flawless analysis while Elemento brings fresh human creativity with an attitude. In addition, you can choose the Tone of AI: Formal, Friendly, Direct or Arrogant. Both AI Entities work offline 24/7. Other features includes: • AI Chat with HAL 9000 or Elemento • Material Packs (subscribers) • 3D-model viewer/import/export • Object Capture: Scan Objects • Favorites section • Offline reference (no Internet needed) • Long list of properties per material • Save Notes per material/resin/filament • Create Designs using Apple Pencil • Support for all iPhone screen sizes • Dark Mode • iPadOS support • MacOS support • Continuous Updates with New Content • UNIVERSAL PURCHASE - One Payment for all Devices New Pro version auto-renew subscriptions: - 1 year (Gold) | 3 month (Silver) | 1 month (Bronze) subscriptions* - Access to all material database ABOUT SUBSCRIPTIONS • Payment will be charged to iTunes Account at confirmation of purchase. • Subscription automatically renews unless auto-renew is turned off at least 24-hours before the end of the current period.
