Cholesterol Testing Unit

Cholesterol is a soft wax-like fatty substance found in all parts of the body.

Our body need a little bit of cholesterol to work properly, but too much cholesterol can be harmful as it forms a fatty plaque which can clog your arteries.

Malcolm Nicholls Limited (MNL) we asked by a leading design company to produce a series of testing units. The client supplied MNL with full 3D CAD in STL format. This data was used to 3D print all of the components to make one full set of the testing units, the process chosen was Stereolithography(SLA) due to its ability to build larger components in one build also giving a better surface finish to work from. Once all of the components were built, they were given to MNL high experienced team of model makers to finish to a variety of levels, from light spark (soft texture) through to exceptionally high levels of gloss.

Once all levels of finishing were completed these models were to be used as a pattern for MNL’s soft tooling process (Silicone tooling). Tools are available in multi-cavity versions in order to produce larger quantities quicker and more economically. Metal inserts are used to hold tight tolerances in bores and critical areas. From the tools a variety of different materials were cast, from a rigid ABS type material for the main body, on the hand held units through to an elastomer over mould. For the main unit a semi-transparent material was required with a small degree of tint. From data to desk this project was completed in a very tight timeframe.
