Abstract: Ti ink compositions for printing, such as ink jet printing, are disclosed. The ink compositions comprise a liquid dispersion of Ti hydride powder having a mean particle size of less than 10.0 microns; a liquid carrier; and at least one surfactant. Methods of making and using the disclosed inks are also disclosed. For example, a finished Ti product can be produced by printing the disclosed ink composition, such as by ink jet printing, to form a green article, heating the green article to dehydrogenate it and form a Ti containing part. The method may further comprise sintering the Ti containing part to produce a sintered Ti product. In an embodiment, the method comprises printing one or more support materials for the ink composition, that comprises solid particles of a metal oxide, a metal carbide, a metal nitride, a polymer, or combinations thereof.

Abstract: A reactive particles supply system that may include an adjustable gas supply unit that is arranged to supply gas and to set a gas condition, a reactive particles supply unit that may be arranged to receive the gas, and an adjustable reactive particles output unit that may include a reactive particles input, a second reactive particles output, and a reactive particles path. The second reactive particles output is configured to output reactive particles towards an opening of a vacuumed chamber. The adjustable reactive particles output unit is arranged to mechanically configure at least one element of the reactive particles path according to the reactive particles condition.

Abstract: A cleanliness monitor, an evaluation system and a method. The cleanliness monitor may include: a first vacuum chamber, a second vacuum chamber, a molecule collector, a release unit, a mass spectrometer, a manipulator that may be configured to move the molecule collector from the first position to the second position, and an analyzer. The mass spectrometer may have a line of sight to an inner space of the second vacuum chamber. The mass spectrometer may be configured to monitor the inner space of the second vacuum chamber and to generate detection signals that are indicative of a content of the inner space of the second vacuum chamber. A first subset of the detection signals may be indicative of a presence of the at least subset of released organic molecules. The analyzer may be configured to determine, based on the detection signals, the cleanliness of at least one out of (a) the first vacuum chamber, and (b) a tested vacuum chamber. The tested vacuum chamber is fluidly coupled to the first vacuum chamber.
