GrandpaCAD now slices your model for your printer

A finished model isn't a print yet. You download it, open the slicer, pick the printer, the filament, the supports, hit slice, and only then find out it's a nine-hour job.

Now you can ask for that in the chat. "Slice it for my Bambu Lab A1, orange PLA" and the model comes back sliced with OrcaSlicer: print time, grams of filament, and every layer in the viewer.

This is a real one. A headphone hook that clamps onto a 25 mm desk, built and sliced from a single message. Drag the bar to walk through the layers.

What you get back

• The print time and the grams of filament, per spool.
• The toolpaths in the viewer, under a Model / G-code switch. Color them by feature, speed, flow or layer height, and show travel moves or hide supports.
• The slicer's warnings in plain words, with what to do about them. Floating parts, a bed that's too hot for the filament, supports that weigh more than the part.
• A file to download: .gcode.3mf for Bambu Lab printers, .gcode for everything else.

The agent picks the settings and tells you why

It built the part, so it knows what the part is for. For the hook it wrote: "I'll prepare it lying on its side for strength, with five walls, 35% infill, and no supports." A figurine gets tree supports and thinner layers. A snap-fit gets its first layer pulled in so the bottom edge still fits.

Before the first slice it asks what's loaded: the material and color of each spool, and whether you have an AMS, MMU or CFS. Say it up front and it skips the question.

Change a setting, get a new slice

The settings worth changing for this model show up in the parameters panel, next to the model's own dimensions. On the hook that was layer height, wall count, infill and supports.

Here's the hook with the infill dropped from 35% to 20%:

No new message, no generation used. Change the desk thickness instead and the model is rebuilt and sliced again in one go.

Set your printer once

Pick your printer, nozzle and plate in Settings → Generation. The list comes from OrcaSlicer's own profiles: 372 printers from 60 brands, including Bambu Lab, Prusa, Creality, Elegoo, Anycubic, Qidi, Sovol and Voron. Printing on someone else's machine today? Name it in the message.

Supports that come off clean

One spool: tree supports for figurines, normal supports for flat overhangs, with a gap that lets them snap off.

Two spools: tell the agent you have PETG next to your PLA (or the other way round) and it prints only the contact layers in the second material. PETG doesn't bond to PLA, so the support lifts off and the underside stays smooth.

What it costs

Slicing is free. It doesn't use a generation, and neither does a re-slice. Downloading the G-code is part of the paid plans, same as downloading the model.

It only happens when you ask. The agent may offer once when a print model is done, and that's it.
