Obloid turns sketches, text prompts and photos into 3D printable models, then gives you the tools to customize, fix and cut them for your printer. Export STL, 3MF, OBJ or GLB, ready for your slicer. AI TOOLS • Sketch to 3D: draw a doodle on the canvas and get a colored 3D model back. • AI Model Generator: describe a figure, animal or prop, or attach a reference image. Sculpted mode makes characters and figures. Parametric mode makes exact parts with real sizes. • CAD Agent: describe a part, then refine it message by message. • AI Part Splitter: split a model into separate parts you can print one by one. PRINTABLE GENERATORS Pick a maker, adjust it with sliders and watch it update in 3D. No AI credits needed. • Keychains and pet tags • Nameplates and 3D text • Photo bookmarks and photo puzzles • Hinged boxes with dividers • 3D QR codes and cookie cutters • Phone stands, desk clamps, hanging planters and spinning tops UTILITIES • STL Cutter: too big for your print bed? Draw a seam, add connectors and export the parts. • STL Repair: fix non-manifold meshes before you slice. • Make Mesh Printable: rebuild broken meshes into a closed STL. • Color 3MF Splitter: split a painted multi-color 3MF into separate color parts. • 3D Print Timelapse: turn sliced G-code into a layer-by-layer build video. • Converters: turn PLY files, 3D Gaussian splats and point clouds into printable STL. EXPORT Export STL, 3MF, OBJ or GLB. Multi-color models export as a 3MF with filament slots assigned, or as one STL per color. Made for makers, 3D printing hobbyists, teachers, students and designers who want to print their ideas without learning CAD. AI tools run on credits. Obloid Pro includes fresh credits every renewal.

About

Forge Slicer

Read full description

Forge is a complete 3D printing slicer that runs entirely on your iPhone. Import an STL, place it on the bed, scale and rotate it, slice it, preview the toolpaths layer by layer, and export G-code to your printer — no laptop, no account, no upload. NOTHING LEAVES YOUR PHONE Forge contains no networking code at all. Your models are parsed, sliced and exported on the device. There is no account to create, no cloud sync, no analytics and no ads. That is not a setting you switch on — it is how the app is built. A REAL SLICER, NOT A VIEWER - Draft, Standard and Fine presets to start from - Layer height and first-layer height - Wall count, top layers and bottom layers - Five infill patterns — Lines, Grid, Triangles, Gyroid and Concentric — with adjustable density - Nozzle and bed temperature, with a separate first-layer temperature - Print speed control - Automatic retraction and a first-layer skirt - True top and bottom surface detection, so solid faces land where they belong - Filament length, weight and estimated print time before you commit SET UP FOR YOUR PRINTER Bed width, depth and maximum height. Nozzle diameter. 1.75 mm or 2.85 mm filament. Heated or unheated bed. Origin at the corner or at the bed centre for delta machines and some cartesians. SEE IT BEFORE YOU PRINT Preview the generated toolpaths layer by layer. Scrub through the model and see exactly where walls, infill and solid surfaces go — before you commit filament to it. EASY TO GET MODELS IN Open an STL from Files, iCloud Drive, AirDrop, Mail or Safari — Forge appears in Open With across the system. Six sample models are built in, including a 20 mm calibration cube, so there is something to slice the moment you install it. A built-in list of model sites points you at Printables, MakerWorld, Thingiverse and Thangs. EXPORT ANYWHERE AirDrop G-code straight to your Mac, email it, or save it to Files and copy it to a USB drive or SD card. You can also export the edited mesh back out as an STL, with your scale and rotation baked in. SHORTCUTS Import, slice and open models from the Shortcuts app. BUILT FROM SCRATCH Forge's geometry kernel was written specifically for this app and is checked against a verification suite of solids with hand-computed answers. Integer-precision arithmetic means contours close reliably instead of almost closing. Forge is free. No in-app purchases, no subscriptions, no ads.
