Where Can I Buy a TD-1
Big news
The TD1s from BIQU (Big Tree Tech) is available for preorder at Presale as of 17 May 2025 with deliveries starting in June.
The TD-1 is not made by HueForge, but by Ajax-3D which was started by a community member. TD-1s used to sell out quickly and were often out of stock everywhere, but not any longer once the TD1s starts to ship.
The list of Resellers is available at Ajax-3d
Why is the TD I get from the TD-1 Different from the HueForge Library?
The library TD values in HueForge are taken from just one or two spools of filament. Over time, we have learned that there can be a large variance in TD between batches or in some cases, parts of a spool. The library values are NOT definitive and your TD-1 is giving you the correct value for YOUR spool.
How Much Variance in TD Should I Expect?
TD Varies in a spool depending on manufacturer. Even those manufacturers that control for TD see variance of +/-10%. Some users are concerned when the same piece of filament varies by 0.1-0.2 between insertions. This is a non-meaningful change that will have no impact on the prediction in HueForge. In fact, if you prefer to round to the nearest 0.5mm on TD, you will not see a difference in the predicted result.
My Colors are Off
The TD-1's primary goal is TD and it measures this very well. Color is something we wanted to have as well because it is useful, but the TD-1 measures color of roughly 1x3mm of filament. No color sensor is going to be perfect at that scale. It is well known that Gray comes in somewhat green, likely due to the LEDs that are on the RGB sensor. Most of the time, if you double click on the color swatch and edit the Green channel to be equal to the next highest color channel (either Red or Blue), you will get a pretty close gray value. Most other color issues tend to be too bright and a brightness adjustment in the same dialog will let you fix that value.
Efforts to improve color accuracy as much as possible have resulted in a new version of the TD-1 firmware. Ajax has previously prioritized production to meet demand. With the next minor release of HueForge a new feature to support this update will be built in. The new firmware enables a on-time calibration feature to correct the previous problems with color rendering. The improved color capability is already part of the BIQU TD1s and is backward compatible with all existing TD-1 units with the 2.0 firmware update.
