ABOUT ROBOFORGE

RoboForge brings 3D modeling and slicing together in one program. Design a part, check it for printing problems, slice it, and prepare it for your printer without exporting it to another application. It includes 413 models, support for 25 FDM printer models and five generic printer classes, beta support for four resin printers, and eight language options. Modeling and slicing run locally, with no account or internet connection required.

BUILD IT. SLICE IT. PRINT IT.

A typical 3D printing workflow involves designing an object in one program and preparing it for printing in another. RoboForge puts both jobs in the same workspace. Create a model, inspect it for potential problems, find a better printing orientation, generate the toolpaths, and get it ready to print without repeatedly exporting and importing files.

BUILD IT

Start with shapes that remain editable. Create a box, cylinder, sphere, cone, torus, tube, wedge, or pyramid. These primitives stay editable: change a dimension, and RoboForge rebuilds the mesh. You can also draw a 2D profile and extrude it into a solid, a practical starting point for many custom parts.

Push and pull faces with precision. Drag any flat face or enter an exact distance. Push a face through the opposite side of an object to cut an opening instead of extending the face through the back.

Sketch directly on a surface. Drawing on a face divides it into separate regions that can be edited independently. Draw a circle on a block, for example, and you can raise the circular region into a boss or push it down into a pocket. The resulting solid remains watertight.

Combine and cut solids. Union, difference, and intersection operations produce a single watertight outer surface without unwanted internal geometry. Faces containing holes remain usable as individual faces, so you can continue to Push/Pull them instead of working around fragmented surfaces.

Create holes for real fasteners. The Hole Wizard includes M2-M12 fastener sizes, close, normal, and loose clearances, tapping-drill sizes, and plain, counterbored, or 90-degree countersunk holes. Shrinkage compensation helps account for undersized holes in FDM prints.

Generate functional threads. Create actual ISO metric helical threads with a 60-degree thread profile. Internal and external clearances are adjusted in opposite directions to help printed bolts and nuts fit together.

Use a complete set of shaping tools. Fillet, chamfer, hollow to a specified wall thickness, lathe, loft, Follow Me, offset, inset, mirror, and create linear or polar arrays. If a part is too tall for your build plate, split it into pieces and add alignment pins for assembly.

Edit vertices directly. Move the points that define an object's geometry. When an edit makes a face nonplanar, RoboForge divides it into planar faces and shows the new edges instead of leaving an invalid polygon behind.

Lock geometry you want to preserve. Locked objects can still be moved, rotated, scaled, laid flat, or combined with other solids, but their existing geometry is protected from accidental edits.

Import and repair meshes. Work with imported objects, including complex meshes containing up to 250,000 triangles. Repair tools can weld vertices, close holes, correct normals, and remove degenerate faces. One-click automatic repair runs these steps together.

IMPORT MORE THAN 3D MODELS

Turn fonts into printable text. Drop a TrueType (.ttf) font onto the build plate and enter your text. RoboForge uses the font's outlines and spacing, preserving the interior openings in characters such as O and 8 as actual holes.

Turn SVG artwork into editable profiles. Import SVG paths and convert them into outlines you can Push/Pull. Curves are flattened with attention to both gentle sweeps and tight corners so the resulting shapes stay manageable and smooth.

Make lithophanes from images. Convert an image into a thickness-based 3D relief and inspect a live thickness preview before committing to a lengthy print.

CHECK PRINTABILITY BEFORE YOU PRINT

RoboForge examines a model for issues that could interfere with printing. Problems are identified in plain language, with a one-click correction where an automatic fix is available.

Checks include unsupported overhangs and walls thinner than the selected nozzle, both with heatmaps; open holes in the mesh; self-intersecting surfaces; objects outside, below, or floating above the build plate; collisions between parts; and tall, narrow objects that may be unstable during printing.

Automatically find a better orientation. Press Shift+A to evaluate the model's flat faces and choose an orientation that reduces unsupported overhangs while maximizing contact with the build plate.

SLICE IT

Generate actual printing instructions, not just a preview. RoboForge produces FDM G-code toolpaths that can be inspected before printing.

It supports 25 FDM printer models across Bambu Lab, Creality, Prusa, Sovol, Elegoo, Anycubic, and Voron, along with five generic printer classes. Six process presets range from 0.28 mm Draft to 0.12 mm Fine. Start and end G-code is generated for the selected machine, with build-volume checks based on its specifications.

Control walls, surfaces, and bridges. Set perimeter count, print order, and seam behavior. Top and bottom solid layers are calculated in relation to neighboring layers. Bridge detection adjusts movement speed, cooling, and line direction to span unsupported gaps.

Choose from seven infill patterns, or draw your own. Grid, lines, triangles, gyroid, honeycomb, and concentric infill are tested for consistent material use at equivalent density settings. Lightning infill uses branching structures to support upper surfaces while leaving much of the interior empty; it is designed to use substantially less material, potentially around one-fifth as much as grid infill. You can also sketch a custom repeating infill tile, choose its density, and save the pattern inside the project file.

Use removable tree supports. Tree supports narrow where their branches meet the model and use reduced flow to make separation easier. In one example, a mushroom-shaped model requires 11.4 g of grid supports but only 5.2 g of tree supports.

Place seams where you want them. Click the model to choose where wall loops begin. RoboForge places the seam along the nearest edge rather than forcing it onto a corner, allowing you to position it in the middle of a face.

Keep small details printable. Gap filling generates toolpaths for thin details, such as a 0.4 mm rib or the stem of a letter, and adjusts extrusion flow to the actual available area to limit bulging.

Fine-tune the print. Features include brims, skirts, rafts with release gaps, ironing, adaptive layer heights, elephant-foot compensation, vase mode, fuzzy skin, coasting, per-object settings, modifier volumes, support blockers and enforcers, custom G-code at selected heights, and Marlin and Klipper G-code flavors.

Inspect the toolpaths. Click a toolpath to see the G-code line that generated it. Move through layers, color them by feature, speed, extrusion width, or layer number, and show or hide travel moves.

Slicing runs in the background, so RoboForge remains usable while it processes your model.

CALIBRATE IT

Five calibration towers generate their own test G-code. Each tower changes the setting being tested from one band to the next, so you do not have to edit G-code manually. Test temperature, retraction, flow, pressure advance, and maximum volumetric flow rate.

Additional calibration models include a 20 mm cube, overhang test, bridging test, tolerance test, and test boat.

413 MODELS INCLUDED

Explore 413 ready-to-use models in 16 categories, including functional parts, moving mechanisms, toys, games, chess sets, robots, vehicles, miniatures, garden items, organizers, and Halloween and Christmas decorations. Search by name or keyword, such as "gear," "castle," or "tray." Each model includes a rendered preview and a short description.

The library distinguishes between two types of models:

67 procedurally constructed models use the same lathes, sweeps, and Boolean operations as RoboForge's modeling tools. They arrive as editable geometry you can reshape, Push/Pull, and cut.

346 cataloged mesh models can be scaled and cut, but they do not include underlying editable construction profiles.

Multi-part designs retain their separate components. A chess set may load as 16 objects, a disassembled truck as eight, and a hinged box as separate box, lid, and pin components. Pieces retain their individual colors and are positioned alongside anything already on the build plate. Mechanical clearances are incorporated into designs that need moving parts.

Each included model is checked for a watertight mesh, consistent face orientation, positive volume, proper placement on the build plate, and fit within the supported build area.

PRINT IT

Export verified G-code. Before export, RoboForge can read the generated file back and run a dry check of the toolpath's actual extents against your printer's build volume.

Connect to a printer. Send jobs over USB to compatible Marlin-style firmware, with line-by-line handshaking, pause, resume, cancel, a live console, and progress reporting. Network printing is available through OctoPrint, Moonraker, and PrusaLink. A built-in printer simulator lets you explore the Device tab even when no printer is connected.

Print technical views on paper. Create a sheet containing four views of your object: one isometric and three orthographic views. Adjust the viewing angles and print on A4, A3, or US Letter paper.

EIGHT LANGUAGE OPTIONS

RoboForge includes English (US), English (UK), Spanish, French, German, Russian, Japanese, and Chinese. Change the language in Settings to localize the interface, all 30 pages of the manual, the glossary, command descriptions, settings, and printer and filament notes.

Terminology is kept consistent throughout the application, with automated checks during each build. If you select a language you cannot read, press Ctrl+Shift+F1 to return to English.

XBOX-STYLE CONTROLLER SUPPORT

Plug in an Xbox-style gamepad and press a button to begin. Use the left stick to move a pointer in the 3D workspace and A to click, giving you access to the same tools available with a mouse. The right stick rotates the view. Hold B to tumble a part and release it to lay the part flat. Press Y to cycle through standard views.

Click the left stick to highlight the tool row, move through its controls with the stick, and confirm with a trigger. Mouse and keyboard controls remain available at the same time; gamepad support adds another way to work without replacing the usual one.

START WITH A GUIDED PROJECT

When you first open RoboForge, it offers an eight-step guided project to make a printable drawer tray in approximately ten minutes. You perform every action using the normal tools. The guide checks your actual progress before marking a step complete, confirming, for example, that the object exists, its dimensions are correct, or hollowing has reduced its volume.

Skip steps, close the guide, or return later: RoboForge remembers your progress. There are also 20 achievements to earn as you explore the program.

LOCAL, PRIVATE, AND OFFLINE

Both modeling and slicing run on your computer. Your designs are not uploaded, no account is required, and the core program works without an internet connection. Autosave maintains recovery copies of your work, including versions that were not selected for restoration.

CURRENT LIMITATIONS

Resin printing is in beta. Four MSLA printers are currently included: Elegoo Mars 4 Ultra, Elegoo Saturn 4 Ultra, Anycubic Photon Mono M5s, and Creality HALOT-MAGE PRO. Beta features include supports, hollowing, and .sl1 output. Screen specifications and build volumes are based on manufacturer information. Exposure and lift settings are initial estimates for standard gray resin, not printer-and-material-specific calibrations. RoboForge identifies these values as starting points; you should verify and tune them for your resin before attempting a long print.

Bambu printing uses a USB transfer workflow. The Bambu profiles include machine-specific build volumes and motion limits for modeling, layout, checking, and previewing. Direct HTTP G-code upload is not provided, and the start G-code includes a visible notice about this limitation.

Printer profiles are based on published specifications. Build volumes, bed shapes, origins, nozzle sizes, and firmware settings are configured from manufacturer information. Acceleration, jerk, and retraction values are reasonable defaults for each printer class and may need calibration for your particular machine.

Full multi-material printing is not yet supported. Objects can store an extruder index, and tool changes can be written when that index changes. However, RoboForge currently uses a single filament profile and does not generate a prime tower.

The interface does not use placeholder controls. Available controls are intended to perform the functions they describe.
