What are the maximum dimensions for 3D printing, and how do they vary by technology?

The maximum size for 3D printing varies depending on the technology used. Here are the maximum dimensions for each technology:

1. Multi Jet Fusion (HP MJF): Maximum size: 380 x 284 x 380 mm Best for production or engineering usage, and is considered the most premium option.
2. Selective Laser Sintering (SLS): Maximum size: 356 x 356 x 400 mm and 340 x 340 x 600 mm Best for production or engineering usage, and is considered a premium option.
3. Stereolithography (SLA): Maximum size: 1400 x 700 x 500 mm Best for producing displays, souvenirs, and trophies, and is considered a low-price option.
4. Fused Deposition Modeling (FDM): Maximum size: 250 x 210 x 210 mm Best for hobbyist or standard usage, and is considered the lowest-priced option.

Note that pricing is largely dependent on the printing technology, material usage (size), and model complexity. Additionally, hollowing out a part can help reduce the price of a 3D printed part, but this may also affect the strength of the part.
