Rapid Prototyping involved creating a working model of various parts of the system at a very early stage, after a relatively short investigation. The method used in building it is usually quite informal, the most important factor being the speed with which the model is provided.
There are water-and solvent-based -- also called oil-based -- polyurethane varnishes. Water-based polyurethanes are more environmentally friendly and safer to use than solvent-based, but they are not as resistant to wear and tear as solvent-based products.
Properly purging the solvents from butane honey oil (BHO) is a vital production step and it is often overlooked. For health reasons, it is vital to remove the solvents used to create BHO such as butane.Many producers use high quality materials when processing BHO and then use low quality purging equipment or processes and end up high levels of undesirable material left behind.hen solvent-extracted product or BHO is inhaled only 5% of the inhalants are non-cannabinoids. BHO or Butane Honey Oil is created when a solvent (typically butane) is combined with raw plant material.
