Description: a naturally occurring anionic polymer typically obtained from brown seaweed due to its biocompatibility, low toxicity, relatively low cost, although the addition of divalent Ca2+ (calcium ions) results in mild gelation. It's a water-insoluble, gelatinous, cream-coloured substance that can be created through the addition of aqueous calcium chloride to aqueous sodium alginate.

Common use: in biology, but primarily known for its healing properties due to the compound's ability to encase enzymes in order to simulate new plant tissue.

Description: a cellulose gum is used in food as a viscosity modifier or thickener, and to stabilize emulsions in various products including ice cream. It is synthesized by the alkali-catalyzed reaction of cellulose with chloroacetic acid.It is also a constituent of many non-food products. Knitted fabric made of cellulose (cotton or viscose rayon) may be converted into CMC and used in various medical applications.

Common use: It is used primarily because it has high viscosity, is nontoxic, and is generally considered to be hypoallergenic as the major source fiber is either softwood pulp or cotton linter.

Description: is a galactomannan polysaccharide extracted from guar beans that has thickening and stabilizing properties useful in food, feed, and industrial applications.The guar seeds are mechanically dehusked, hydrated, milled and screened according to application. it has almost eight times the water-thickening ability of other agents (cornstarch) and only a small quantity is needed for producing sufficient viscosity. In addition to guar gum's effects on viscosity, its high ability to flow, or deform.

Common use: One use of guar gum is a thickening agent in foods and medicines for humans and animals.

There are two types of configuration files:

  • Machine Definition
    • fablabbcn_pasteprinter.def.json
  • Extruder Definition
    • fablabbcn_0.def.json

Copy each of these into the respective configuration folder in Cura. The paths are as follows:

  • C:\Program Files\Ultimaker Cura 5.2.1\share\cura\resources\definitions
  • C:\Program Files\Ultimaker Cura 5.2.1\share\cura\resources\extruders
