Career paths, a guided route from zero, and a figure on every lesson. CAREER PATHS Pick what you want to become and get an ordered route to it, built from the lessons, tools and data already in the app. Six paths, each showing how engineers actually get qualified — in six countries. THE LEARNING PATH One guided route from the very start through to laminate analysis, so you always know what to read next. 3D PRINTING The whole field in one place: the seven process families, the machines, the materials, and how to design for them. EVERY LESSON NOW MOVES All 29 articles have an animated figure and a self-check quiz. Watch a polymer cross its glass transition, read an S–N curve, see why a printed part splits along its layer lines — all offline. MORE MATERIALS 44 cited systems, every property still carrying the source, test method and conditions it came from. Also: a refreshed look, a movable shortcut for quicker navigation, and a fix for pages that would not scroll on iPad and Mac. Still free, still fully offline, no account, no ads — and it still collects nothing about you.

v2.0 — Deeper science, and a whole new way in. • Make — a new idea → product guide: pick a material, pick a process, and see where polymers and composites are actually used, across 9 industries and 10 manufacturing processes. • Progressive failure in the laminate calculator — go beyond first-ply failure all the way to ultimate strength, ply by ply. • More materials (POM, PBT, TPU, PVDF), 9 new Learn articles, 27 more Handbook formulas, and expanded Basics. • Everything still fully offline, every value cited, nothing collected.
