Today over 80% of 3D printed parts are made using thermoplastic or thermoset polymers. Metals, ceramics and other composite materials comprise the other 20%. Plastic 3DP parts are manufactured using any variety of 3D printing methods including FFF, DLP, SLA or material jetting processes. Common to all these methods is that the parts are created…

How Do I Choose a Debinding Fluid for 3D Printed Metal Parts?

Metal 3D printing, a subset of additive manufacturing is a dynamic process used to make fully-finished, machine-grade metal parts. There are many types of metal 3D printing methods in use today. However, two-methods stand out for their speed, ease of use and cost-effectiveness. Binder Jetting and Feedstock Extrusion both create parts either by building or extruding…

What is Metal Additive Manufacturing?

Metal additive manufacturing, also known as metal 3D-printing is a process used to make fully-finished, machine-grade metal parts. It is a viable alternative to more conventional large-scale production methods such as subtractive manufacturing or injection molding, and in some instances is eliminating the need for machining altogether.Ideal for producing parts with complex geometries, metal additive…

What Is the Meaning of a Fluid Toxicity Rating, Like a PEL or TLV?

In general, the “toxicity” of a cleaning fluid is measured through the use of 8-hour “time-weighted average exposure limits” (AEL). Similar terms you might find on labels and SDS sheets include “Average Exposure Limits” (AEL), “Personal Exposure Limits” (PEL) and “Threshold Exposure Limits” (TEL). One special term is “Threshold Limit Values” (TLVs) which only are…

Can I Use nPB in My Cleaning System?

nPB is a strong, affordable, versatile, nonflammable industrial solvent. nPB is a great degreaser and defluxer. However, npB does have toxicity worries. nPB is banned in Europe as of July 2020 and other countries currently have nPB under scrutiny. In the 1990s when nPb was first introduced, the toxicity level for nPB (also known as “TLV”, “AEL” or “PEL”) was…

Which Precision Cleaning Fluid Is the Mildest?

Very gentle, mild cleaning often is required when (a) cleaning substrates made from delicate materials, or (b) when the contamination is light, or (c) when the principle contamination being removed is water. Milder solvents generally are noted as having a low Kb value, typically 20-40 or so (a high Kb value is 100+). Many mild solvents…
