3D Printing

Overview

Ithaca Generator has 3 robust workhorse printers, each with different advantages. There is a Benchy on each printer so you can see differences, and they're taped to the top of their respective printer. Each Benchy took 1.5 hours and is sized accordingly so you can get an idea.

Prusa MK2S: small 10 x 8 x 8 inch (250 x 210 x 210 mm) build volume, slowest, but very accurate.

Prints PLA and PETG.

Use an SD card to print.

General remarks: This should be your default printer unless you're printing very large (Xinkebot) or want extra speed/precision (RailCore).

Xinkebot: largest 16 x 16 x 20 inch (400 x 400 x 500 mm) build volume. Relatively fast, but that's because it uses a larger nozzle so it's lower rez, and prints will have minor flaws, but if you're going to do post-processing anyway, doesn't matter.

Prints PLA and PETG.

Can print flexibles with special setup.

Use an SD card to print.

General remarks: This is your go to printer for large prints. It's lower resolution than the others, and the prints won't be as perfectly smooth, but they will be quite good nonetheless.

RailCore: large 12 x 12 x 13 inch (300 x 300 x 320 mm) build volume. Very fast and accurate. Robust workhorse.

Mainly prints PETG. Also good for more experimental filaments such as those filled with carbon fiber. Can print PLA with different nozzle.

Use the web interface to upload and print.

General remarks: Makes beautiful prints quickly. More complex interface and controls than the other printers. While not a strict requirement, it would be better to master the Prusa or Xinkebot before moving on to this printer.

IMPORTANT:

Don't use hairspray any more.

Don't use any sticking aid on the Prusa or the Railcore. They both have special beds that will be very sticky when hot.

Magigoo should be used on the Xinkebot glass bed.
