		+	== Simulation 3D print==
		+
		+	The simulation would focus on printing a 3D model on a 3D printer. This model would be made of multiple materials, so a 3D printer would need a material storage and a switch between them. Each material needed a different temperature and time to print parts of the model, also each material has a different financial value. At the same time, there is a need to consider providing additional cooling that slows down the print to prevent it from warping. There is also a need to consider the influence of the environment, such as ambient temperature, wind or nozzle clogging.
		+
		+	'''Measurement parameters'''
		+	* time of making
		+	* production cost
		+	* nozzle temperature
		+	* time between transitions
		+	* condition of materials
		+	* etc
		+
		+	''' Goals'''
		+	* Measure how long it takes for the model to print.
		+	* What is its financial demands if we take into account the price of the material and the time of its printing.
		+	* If additional cooling needs to be switched on.
		+
		+	'''Tool'''
		+	* Simprocess or vensim - advice?
