No. This is a post process to a HueForge model, not a new way to make HueForge models.

That being said, multiple levels of the same color are less of an issue with this method because they will all end up on the flat surface together and not be as noticeable so it can make some images easier to create.

On a normal HueForge print, each layer is smaller than the one below it. In FlatForge this is not true. Every layer is the exact same size.
FlatForge not only fills in all the layers of an existing HueForge print but it also requires frequent swapping of filaments.

On a Toolchanger this will add minimal time, but on an AMS system will cause much longer delays as spooling and unspooling filament is slow as well as purging the old filament from the nozzle adding waste and time. Still, it is much easier to add extra colors to an AMS system.

HueForge Prints use very low layer heights for blending. The default is 0.08mm but layer heights as low as 0.02mm can be used on 0.4mm nozzles to increase blending and image fidelity.

When flipping a HueForge over to place the image on the bed, you would need to print a first layer at those same layer heights which is very difficult. A single transparent layer at a normal first layer height of 0.16-0.2mm is much easier to get right and also slices faster.

Not at all. Smooth or Holo plates create nice textures for face-down FlatForge prints, but they are not necessary. With the transparent first layer for face down, you can print on nearly any surface.

If you don't want the bed surface involved, you can also print face up and get the standard imprint on the back.

While smaller models don't add much to slice time, larger models or models with many layers add a lot of slicing time because there are many more triangles involved with the oddly shaped models generated for each Color Slider in the print.

Larger prints may require extreme amounts of memory just to slice. Be aware of these limitations when attempting FlatForge. It is recommended to start with smaller prints.

FlatForge has a list price of $20 but an introductory price of $15 for October and November of 2025.

This is a one time fee and will not be repeated. All updates are included in this price with no expiration date.

It is possible that a future version may not be compatible with an older version of HueForge, but you will never lose access to the newest version of FlatForge.

No.
FlatForge will release with a KeyChain maker tool as well as a yet to be announced special feature.

It is also possible to use FlatForge with other plugins.
