3D Print Assistant vs OpenShape3D

Slicer profiles for 100+ 3D printers from Bambu Lab, Prusa, Creality, Anycubic, Elegoo and more, made for Bambu Studio, OrcaSlicer and PrusaSlicer. Choose your printer, nozzle, filament and print goal. 3D Print Assistant builds a practical starting profile with settings you can review and adjust. The core tools are free and need no account. MADE FOR YOUR PRINTER AND SLICER Pick from 100+ printers, including models from QIDI, Sovol, FlashForge, Artillery, Snapmaker and Voron. Each profile follows the slicer that fits the printer: Bambu Studio for Bambu Lab, PrusaSlicer for Prusa and OrcaSlicer for the other brands, with settings grouped under the same tabs as in the slicer. Can't find your printer? Answer four questions and start from a generic profile. FROM PROFILE TO SLICER Export a profile file your slicer can import when it has a matching preset for your printer and nozzle. For every other setup, share the profile as text and enter the values by hand. Switch between Simple for the essentials and Advanced for the full profile. YOUR SETUP, READY TO GO Save printers, nozzles and materials in My Gear. Pick a setup next time and skip the details you already know. Keep the profiles that work for you in Workshop. A CLEARER WAY TO CHOOSE MATERIALS Start from material profiles for PLA, PETG, ABS, ASA, TPU, nylon, PC and carbon fiber blends. Browse filament by category, compare popular choices and see useful details before you select a material. Inventory adds a searchable catalog of 2,089 filament products from 151 brands across 38 material types. KEEP FILAMENT IN VIEW Track spools in Inventory, including color, weight and status. Up to five active spools are free. Pro removes the limit, and with a 3DPA account it syncs Inventory across iPhone, iPad and the web app. GET HELP WITH THE NEXT STEP AI Expert can help explain settings, compare options and troubleshoot a print, also from a photo. It requires an internet connection and a 3DPA account, which you create by signing in with Apple or Google. A new account includes free credits to try it. Also included: a pre-print checklist. The core printing tools work offline after installation; AI Expert and sync need an internet connection. Available in English, Danish, German and Russian.

openshape3d is a direct-modeling CAD app built for touch. Sketch a profile, pull it into a solid, and keep cutting, blending and patterning until the part is done — no desktop, no subscription server, no file conversion dance. Geometry is computed by OpenCASCADE, the same open-source B-rep kernel used in professional CAD. Extrudes, primitives and booleans produce exact analytic surfaces, so a cylinder stays a true cylinder instead of a faceted approximation. SKETCHING • Sketch on a world plane, on any flat body face, or on an offset construction plane pulled off a face • Line, rectangle, circle, arc, ellipse, polygon and text-as-outline tools • Endpoint, midpoint, centre, vertex and grid snapping — draw with Apple Pencil • Trim, move/rotate gizmo, construction geometry, and reusable symbols • A full 2D constraint solver: coincident, parallel, perpendicular, tangent, equal, concentric, symmetric and more • Driving dimensions with inline arithmetic (type 25.4/2) pull geometry to value • The sketch tells you where it stands — fully defined, or how many degrees of freedom remain SOLIDS • Extrude a profile, or push and pull a face directly with automatic booleans: pull to add material, push to cut • Revolve, sweep along a chained path, loft through sections, and helix • Fillet and chamfer edges with live preview and drag-to-size • Shell a body hollow, with optional open faces • Union, subtract and intersect between bodies, computed off the main thread • Split a body with a plane or a sketch profile • Linear and circular patterns with ghost previews • Move, scale, rotate, mirror, translate point-to-point and align VIEWING • Orientation cube, six standard views, isometric and orthographic toggle • One finger orbits, two pan, pinch zooms — the camera never locks up • Section view that clips live against a plane, with a drag arrow and flip • Shaded, shaded without edges, wireframe with proper hidden-line removal, and X-ray • Marquee select with window/crossing semantics, and Select Through to reach a body buried behind others • Isolate to hide everything but the selection MATERIALS AND REFERENCE • Material presets — steel, aluminium, brass, plastics, rubber, wood — plus custom colour with metallic and roughness • Drop PNG or JPEG reference images onto any plane and trace over them MEASURE • Face area, body volume and bounding box on selection • Two-point distance with X, Y and Z deltas over snap points IMPORT AND EXPORT • Import STL and DXF • Export STL, OBJ, 3MF, GLB, USDZ and sketch DXF • Preview your model in AR with Quick Look
