FormNext 2024: My Thoughts on FLSUN's New T1 Pro Delta Printer (Patreon)

Every year, I make it a point to check out the Delta printers from FLSUN, and this year was no exception. Ever since I saw the V400 in 2022, I’ve been closely following their developments in the Delta printer lineup. This year, FLSUN unveiled the T1 Pro, a refined version of their earlier T1 model.

After the mixed reception of the S1 and T1 launches, FLSUN seems to have taken the community’s feedback seriously and incorporated it into their "Pro" models. The highlight of the T1 Pro is its focus on noise reduction. The upgraded CPAP-style cooling system is significantly quieter at 55 dB, though it’s still noticeable at maximum airflow. However, FLSUN didn’t stop there—they’ve invested heavily in optimizing their slicer profiles to further reduce part cooling noise.

Additionally, they’ve introduced firmware updates that make a real difference. For example, they’ve fine-tuned the TMC2160 driver settings to run the motors in StealthChop mode, which reduces motor noise. The result? The T1 Pro is noticeably quieter than its big brother, the S1. That said, it’s probably still louder than the average CoreXY printer, but it’s hard to judge with the noise of a busy trade show.

Personally, the T1 Pro left a strong impression on me. During the S1 and T1 launches, I felt the printers needed more development time. However, the T1 Pro feels like a complete package—a solid product at a good price point.

FLSUN seems to agree. They’re offering a "Pro Silent Module" upgrade for T1 owners, allowing them to bring their printer up to T1 Pro specs. This move reflects the company's willingness to support their customers, showing they’ve learned a lot about their target audience over the past two years. With the T1 Pro and the upgrade path, FLSUN is making a strong case that they’re here for the long haul and committed to meeting their users’ needs.

Well done, FLSUN!
