Building in 3D

AI image tools give you a picture. That is not a model. You cannot walk it, print it, or fix the one dimension that is wrong. This night is about AI that outputs geometry : Blender scenes, Three.js rooms, printable STLs, using tools like GPT-6 Astra that can drive Blender, write the Python, and iterate on a real file. This session, we're exploring what’s now possible with tools like GPT-6 Astra: generating everything from detailed interior scenes and custom furniture to playful web games, interactive walkthroughs, physics simulations, architectural visualizations, and clean, print-ready parts for manufacturing. Bring photos, sketches, or just ideas, Astra and similar models can turn prompts or images into editable 3D geometry in Blender, build walkable rooms, generate parametric components, or set up playable environments for games and the web. The technology excels at the whole 3D pipeline: Creative & Design: Shape prompts, photos, or rough ideas into detailed, editable Blender models. Interactive Experiences: Craft walkable houses, interactive scenes and environments, even export for Unreal or web. Games & Web 3D: Build parametric objects, dynamic scenes, or physics-based structures. Architectural Visualization: Render full rooms, furniture sets, lighting setups, and camera tours. Manufacturing & 3D Printing: Produce clean, functional geometry ready for print (STL/STEP), repairs, or terrain. 3D printing is just one practical and popular application, at its core, this night is about exploring what AI-assisted 3D creation makes possible, across creative, technical, and playful domains. No experience in Blender, coding, or AI is required; come ready to try out new ideas, see what’s possible, and share what you build, whether that’s a game-ready scene, a printable part, or something in between. Start here if this is new: one object or one room, from one or two photos. A mug, a doorway, a shelf, a fitting. Orbit it in the browser or Blender. That is a complete demo. Stretch: a small walkthrough with a choice (floor, wall, light), a parametric piece (maze, mount, case), or a part you would print, wall thickness, export, slice preview. This is not a Blender class and not a talk about the viral clips. Those exist so you can steal the move: iterate, let it use the 3D tool, keep the file. No printer in the room. You do not need one. No Blender degree. No AI experience required. Bring Laptop and charger 1–3 photos of a room, an object, or a broken part. A tape measure in the shot helps Optional: the object itself Optional: Blender already installed, and a ChatGPT / Astra login Steel City AI is a hands-on meetup for people who want to build with AI, not just talk about it. Developers, designers, makers, students, and the AI-curious. No pitches. No long talks. Just builds, demos, and takeaways. Learn by doing. Connect locally. Build something useful.
