to update the printer’s firmware:
OTA firmware update
OTA (Over The Air) firmware updates are
delivered via ethernet or Wi-fi network.
Connect the
printer to the internet as described in the chapter 4.4 Network connection. If a new firmware is
released, the printer will display a notification.
USB firmware update
If your printer is not connected to the internet, you can
download the firmware file from the
official website
https://www.prusa3d.com/drivers
. Download the ZIP file to your computer,
unpack it and place the update file (with .raucb extension) on a
FAT32-formatted USB drive.
Then insert the USB drive in the printer’s USB slot. Then go to
Settings - Firmware
and select the
firmware file from the list.
WARNING! Never turn off or reset the printer during the firmware flashing process!
9. Material Guide
Liquid resins are
photosensitive materials
used for printing on SLA 3D printers. Resins are also
known as photopolymers and they are
cured (solidified) by UV light
- this also includes sunlight.
Compared to filaments for FFF/FDM printers, the major difference is that there are not various
materials such as PLA, PETG or ASA. There’s just THE resin, a base material that can be further
enhanced with
added colors or additives.
Typical effects of additives would be increased
hardness or toughness of the printed object.
The Original Prusa SL1S 3D printer is compatible with 405nm resins.
Resins usually consist of three basic components:
The core
of the resin (monomers and oligomers)
Photoinitiators
- molecules reacting to UV light, which initiate the solidifying process
Additives
- admixtures that change the color and properties of the resin
