Micro-chemical plants are chemical plants that use micrometricsstructures by performing a numbering-up of microdevices. The flow distributor isresponsible for the flow uniformity distribution through these microdevices. Inadequatedesigns reduce the plant performance. Thus, 3D printing is a good alternative to allowfast and economic development to test these distributors. The present research aims toapply 3D printing to manufacturing flow distributors and evaluate the flow uniformityobtained from experimental tests. Three conical distributors with obstacle (CDO) weretested in water flow and values of the non-uniformity flow coefficient (Ф) were obtainedfor each distributor. At low flow rates, was observed the presence of air bubbles thatcontributing to a flow maldistribution. The flow rate increment resulted in a Ф valuesdecreasing, reaching a good flow uniformity with deviation below 2%. Therefore, 3Dprinters are a potential fast manufacturing route at low cost supporting furtherdevelopment of distributor designs with good performance.
