SpeakCAD for the Creality K2 Plus
Custom parts for the Creality K2 Plus: describe them, download G-code sliced for it
Creality's 350 mm enclosed CoreXY with a heated chamber and the CFS multi-colour box, for large ABS and ASA parts. SpeakCAD ships the Creality K2 Plus's own OrcaSlicer profile: describe a part in plain English, watch it render on a virtual 350 x 350 mm bed, edit it by chat, and download a .gcode file, ready for the SD card, the USB stick or the printer's own upload page. Or take the STL or 3MF to your usual slicer. Runs in Safari and Chrome, on a phone or a computer, nothing to install.
How it works
From a sentence to the K2 Plus's SD card
The slicer runs on our side with the same profiles OrcaSlicer ships for the Creality K2 Plus. You choose the print profile and the filament; the printer settings are already right.2
Check it on the K2 Plus's bed
The part renders on a virtual bed the size of the K2 Plus's. The first render usually appears within a minute or two: a new part gets deeper reasoning through the geometry, and small edits land in seconds. Turn it, tap a face to read a size, open the dimensions panel, and see whether it has overhangs that need supports. Anything wrong is one sentence to fix.3
Pick the Creality K2 Plus and its profile
In the download dialog choose the Creality K2 Plus (0.2 nozzle, 0.4 nozzle, 0.6 nozzle, 0.8 nozzle), one of its print profiles (0.06 mm, 0.08 mm, 0.1 mm, 0.12 mm…), a filament, then infill, walls, supports and adhesion. The printer and its last settings are saved to your account.4
Download and print
You get a .gcode file, ready for the SD card, the USB stick or the printer's own upload page, with the estimated print time and filament weight. Re-slicing a design you already downloaded does not spend the 10 credits again; without Pro or Unlimited each slice still spends 5 credits.The Creality K2 Plus profile SpeakCAD slices with

Prompts sized for the K2 Plus
Copy one, change the numbers to yours. Each opens in the editor with the text already typed.“A CFS PTFE guide clip for a Creality K2 Plus: routes a 4 mm tube along the rear top edge, snaps on a 3 mm panel edge with 0.2 mm clearance, 30 mm long, 2.4 mm walls, ASA.”
Open this prompt in the editor“A build plate wall rack for three 350 x 350 mm Creality K2 Plus plates in 8 mm slots 20 mm apart, two keyhole mounts 200 mm apart, 3 mm walls, 320 mm wide.”
Open this prompt in the editor“A monitor riser 320 x 230 x 100 mm printed in one piece, hollow with 20 mm ribs, a 70 x 30 mm cable pass-through at the back, 2.4 mm walls.”
Open this prompt in the editorWhy K2 Plus owners do not need a slicer on the phone
Slicing is the step that keeps 3D printing on the desktop: a design made anywhere still has to pass through Bambu Studio, PrusaSlicer or Cura on a computer. SpeakCAD runs OrcaSlicer on its own servers with the profile OrcaSlicer ships for the Creality K2 Plus, so the phone that typed the description also downloads G-code. The desktop slicer stays the better choice for arranging many parts on one bed or for exotic settings; for one part at a time, the download dialog covers the profile, the filament, infill, walls, supports and adhesion.
Slice your own STL for the K2 Plus
Already have the file, a Printables or MakerWorld download or a part from your own CAD? The online slicer slices an STL or 3MF of up to 50 MB with the same Creality K2 Plus profile, without the AI: layer heights from 0.06 to 0.56 mm across its nozzles, filament presets for PLA, PETG, ABS, ASA, TPU, PLA-CF, PETG-CF, PC, PA, PA-CF, infill, supports, walls and bed adhesion. You download a .gcode file, with the print time and filament weight. The online slicer gives every account 1 free slice, its first (a free account, no card). After that, a slice uses one slice from a Slicer pack (20 slices for $3, once, never expire) or 5 credits, and slicing is included in Pro and Unlimited. Re-slicing the same file with other settings within 10 minutes is free. Open the online slicer.
Parts that fit the K2 Plus
The Creality K2 Plus's 350 x 350 mm bed and 350 mm height are what the virtual bed in the viewer shows, so a part that looks too big is too big. Ask for a part to be split into two halves with alignment pins when it does not fit, or for a flat print orientation when it would need supports. The examples above and the library parts below all fit.
Parts that fit the first time
The Creality K2 Plus prints slightly differently from the next printer, which is why holes come out tight and lids loose. Fit Check cuts a five-minute test slice from the interface that must fit, you report too tight, perfect or too loose, and every model after that is built with the clearance your K2 Plus needs. The test slice downloads free as STL or 3MF. How Fit Check works.

Questions
Yes. The Creality K2 Plus is one of the 380+ printers in the slicer catalog, with 4 nozzle variants and the print and filament profiles OrcaSlicer ships for it. Pick it in the download dialog and download G-code; it is saved to your account for next time.
No. SpeakCAD slices on its servers and gives you a .gcode file. Copy it to the SD card or USB stick the K2 Plus takes, or upload it through the printer's own web page or app. If you prefer your own slicer, download the STL or 3MF instead.
The print profile (layer height and speed presets from the Creality K2 Plus's profile), the filament profile (the printer's own and the OrcaSlicer library: Generic PLA, PETG, ABS, ASA, TPU, carbon-fibre blends and hundreds of branded filaments), infill, wall count, supports and bed adhesion. Nozzle temperature, bed temperature and speeds come from the profiles you pick.
The virtual bed in the viewer is sized from the Creality K2 Plus's profile (350 x 350 mm), so you see it before slicing. Ask for the part to be split into two pieces with alignment pins or a dovetail, or for a different orientation; each is one sentence.
Sliced downloads are included in Pro ($14.99 a month, 200 credits) and Unlimited ($39.99 a month); with Starter credits ($5 once for 50 credits, no subscription) a sliced download spends 5 credits on top of the usual 10. Re-slicing a design you already downloaded does not spend the 10 credits again; without Pro or Unlimited each slice still spends 5 credits. STL and 3MF downloads are always available.
Yes. Upload the STL or 3MF (up to 50 MB) to SpeakCAD's online slicer, pick the Creality K2 Plus, choose the layer height, filament, infill and supports, and download a .gcode file. It slices with the same OrcaSlicer profile as the editor's G-code download, in the browser on a computer, a Chromebook, an iPad or a phone. The online slicer gives every account 1 free slice, its first (a free account, no card). After that, a slice uses one slice from a Slicer pack (20 slices for $3, once, never expire) or 5 credits, and slicing is included in Pro and Unlimited. Re-slicing the same file with other settings within 10 minutes is free.
Yes. The editor runs in Safari on iPhone and iPad and in Chrome on Android; the file lands in Files or Downloads, ready for the card or the printer's app. The same project opens later on a desktop.
