The FLSUN T1 Pro is a robust and reliable printer that excels in producing high-quality prints. While its build volume is slightly smaller than the S1 Pro, it still offers plenty of room for larger projects.

The FLSUN T1 Pro also excels in speed, with a maximum printing speed of 1000mm/s and a max acceleration of 30000mm/s². Although slightly slower than the S1 Pro, it still outperforms the vast majority of non-commercial printers on the market.

Comparison Summary

Why Speed Matters

In 3D printing, speed is more than just a convenience—it's a critical factor that can significantly impact your workflow and productivity. With the FLSUN S1 Pro and T1 Pro, you can reduce print times drastically, allowing you to take on more projects and achieve more in less time.

Comparison Summary

• Printing Speed: The FLSUN S1 Pro leads with a max speed of 1200mm/s, followed closely by the T1 Pro at 1000mm/s.

• Acceleration: The S1 Pro offers a higher max acceleration, ensuring quicker starts and stops.

• Efficiency: Both printers are designed to save you time, outpacing their non-commercial counterparts by a factor of three.

• Quality: Despite their speed, both printers maintain high-quality prints, ensuring you don't sacrifice detail for speed.

Advanced Material Printing

Both the FLSUN S1 Pro and T1 Pro feature enclosed designs, which are crucial for printing more advanced materials. The enclosed environment maintains consistent temperatures, reducing the risk of warping and improving adhesion. This makes them suitable for materials such as ABS, ASA, and PC, which require higher and more stable temperatures for successful printing.

Conclusion

In summary, the FLSUN S1 Pro and T1 Pro are exceptional choices for anyone looking to speed up their 3D printing projects. The S1 Pro excels in speed and high-temperature performance, making it ideal for those who need rapid production and advanced material capabilities. The T1 Pro, on the other hand, offers a larger build volume and still maintains impressive speed, making it a versatile choice for various projects.

Choosing between the two will depend on your specific needs: if speed and advanced material printing are your top priorities, the S1 Pro is the way to go. If you need a larger build volume for bigger projects while still enjoying fast print speeds, the T1 Pro is an excellent choice.

And I am going to take a moment to discuss the Maximum speed of hardware, vs actual real world printing, since this is a topic of controversy when getting into this level of speed.

Understanding Maximum Printing Speed in 3D Printing

When we talk about the maximum printing speed of a 3D printer, it's important to understand that this figure doesn't mean the entire print will be produced at that speed. Here’s a detailed explanation of what it actually means:

1. Peak Performance

• The maximum printing speed, such as 1200mm/s for the FLSUN S1 Pro or 1000mm/s for the FLSUN T1 Pro, represents the peak speed the printer can achieve under ideal conditions. This peak speed is typically reached during simple, straight-line moves or travel moves between printed sections where there’s no material being extruded.

2. Material and Physics Constraints

• Filament Behavior: Different materials have varying melting and cooling properties. For example, PLA and ABS behave differently when extruded at high speeds. Faster speeds can lead to under-extrusion, poor layer adhesion, and reduced print quality.

• Thermal Dynamics: The hot end and build plate temperatures must be perfectly balanced to ensure the material stays at the correct consistency for extrusion and adhesion. Exceeding these speeds can compromise the thermal management.

3. Detailed vs. Simplified Areas

• Complex Geometry: When printing detailed or intricate sections of a model, the printer slows down to ensure accuracy and detail. These sections require careful control of the extrusion rate and movement to avoid defects.

• Travel Moves: During travel moves, where the printer head moves between different parts of the print without extruding, the speed can be maximized without compromising the print quality.

4. Technological Limitations

• Acceleration and Deceleration: The printer can't instantly accelerate to its maximum speed or stop on a dime. It needs time to ramp up and slow down, which means average speeds are often lower than the peak speed.

• Current Material Chemistry: We are at the limits of what current materials can handle. Until new high-speed-specific filaments are developed, we must work within these constraints. Materials need to flow consistently at high speeds and maintain integrity once deposited, which is challenging with today's options.

The Glass Ceiling of 3D FDM Printing

Given these factors, the maximum printing speed is more about the printer's capability in optimal conditions rather than a constant printing rate. The field of 3D FDM printing is continuously evolving, and material science plays a significant role in pushing these limits. For now, we have to acknowledge this "glass ceiling" – the balance between speed, material properties, and print quality.

Advances in material technology and printer design will continue to push these boundaries, but until then, understanding the nuances of maximum speed helps set realistic expectations for what these impressive machines can achieve.
