What slicer to use for the Tractus3D T850P
None of the slicers in SimplyPrint's cloud has a ready-made profile for the Tractus3D T850P, but it takes standard G-code: start from a similar printer's profile and set the bed size, height and nozzle to match.

Automatic Profile Updates: Profiles are automatically checked and fetched from the slicer GitHub repositories every day, as well as from our own open-source community-driven slicer profile database. This ensures you always have access to the latest profiles.
Note: Other slicers, such as Simplify3D, ideaMaker, SuperSlicer and KISSlicer, aren't in our cloud, so we don't track their profiles. They may still work well with your Tractus3D T850P: check the slicer's own documentation or forums for a profile. You can also contribute profiles to our open-source slicer profile database on GitHub.

Automate the Tractus3D T850P
There's no plate swapper or auto-ejection kit for the Tractus3D T850P in SimplyPrint yet, but AutoPrint can still keep it printing: once the plate is clear, it starts the next job from your queue.
Ways to automate it
- Your own ejection G-code Write the routine that clears your plate, and AutoPrint runs it after every print.
- A robot arm, or anything with an API Tell SimplyPrint the plate is clear through the API or a webhook, from a robot arm or your own system.
- Clear it by hand, keep the queue AutoPrint waits for you to mark the plate clear, then starts the next job.
AutoPrint comes with the Pro plan and up.

What filament can the Tractus3D T850P print?
Filament compatibility for the Tractus3D T850P: the materials it can handle, judged from its hotend, bed, chamber and enclosure.
| Filament | Suitability | Notes |
|---|---|---|
| PLA | Great | The easiest filament to print. Works on almost any printer; a heated bed helps adhesion but is not required. |
| PETG | Great | Comfortably in range (PETG likes a ~230-250C hotend and a ~70-85C bed). |
| TPU & flexibles | With care | Possible, but a Bowden extruder makes flexibles harder - print slowly and prefer firmer (higher-shore) TPU. |
| ABS & ASA | Great | Enclosed, with a hot enough hotend and bed: ABS and ASA print well. |
| Nylon (PA) | Good | Doable with care - dry the filament thoroughly, and an enclosure helps a lot. |
| Polycarbonate (PC) | Good | In range for PC. Dry the filament, print slowly, and use an enclosure for the best results. |
| Carbon-fiber & glass-filled | With care | Possible if you fit a hardened or wear-resistant nozzle - the abrasive fibers quickly wear a stock brass nozzle. |
Tip: this is a general guide from the printer's specs - always check your filament's recommended settings. With SimplyPrint you can save a profile for each spool and track exactly what filament you have in stock.
