	*Recommended is 0.8 and larger nozzles for fast printing of large objects. The worst case accuracy For 3 mm filament is such that layer thickness can vary by 20% if 20% filament width tolerance is used in the absence of a filament width sensor. This is such that the outer surface can have up to 160 micron (<1/5 mm) naccuracy. For bulk objects, such as 2x4 lumber, that means overall one-~~millionty~~ deviation, which is still orders of magnitude better than commercial lumber.		*Depending on the amount of effort and skill of the producer - filaments can be made up to tightly-controlled composition if the feedstocks are known and uniform. With nonuniform feedstocks, the challenge is to work out blends that work - and this is a good point for crowdsourcing of thousands of different formulas based on localized sourcing.
			*Note that Shilament formulas with hard-to-print materials such as polyethylene, propylene, or high temperature ones such as PEI - can be printed only using a high-temperature printer. OSE is developing such a printer in 2020.

	If a.filament width sensor is utilized,.this ~~.eans~~ that prints are perfect regardless of filement tolerances.		If a filament width sensor is utilized, this means that prints are perfect regardless of filement tolerances.

			The mixtures must be quality controlled and compatible so that materials with similar melting points and properties are used to attain quality prints. There is a whole range of formulas to be developed for what exactly is a suitable filament for 3D printing. The advantage of plastics is that a wide range of mixes, copolymers, blends, and composites can be used combining plastic, rubber, wood, ceramic, metal, and other powders, fibers, or admixtures.
