Because some 3D printing filaments are hygroscopic, meaning that they absorb moisture from the air, prolonged exposure to even moderately humid room air causes moisture saturation. After 150 hours in standard conditions, PLA filament may swell up to 40 micrometers before reaching its saturation point. 3D printers rely on tight tolerances and extremely small layer heights. Before the print even gets underway, an increased filament diameter of even 20 – 40 microns, (roughly the width of a human hair) can derail a build before it ever begins.
An Alternative Drying Solution Replaces Traditional Methods As the industry utilizes a high-temperature reflow process, moisture sensitivity in SMT remains a constant problem. Serious manufacturing defects and failures are much more likely to occur later when products are in the field, which can be traced to improper storage and handling of components and PCBs during … Read moreIssues associated with moisture problems
Manufacturing Uses of Desiccator Cabinets for Printed Circuit Boards (PCBs) The discussion regarding ‘dry box’ or desiccant storage of MSD’s (Moisture Sensitive Devices) has increased over the past years with the introduction of new IPC Joint Industries Standards such as IPC/JEDEC J-STD-033a and J-STD-020. Manufacturers are becoming aware of the possible benefits of ultra-low humidity … Read moreDry Box Desiccant Storage within the PCB Manufacturing Environment: Uses, History, Selection, and Performance
What is a desiccant Dry Cabinet? A desiccant dry cabinet is an enclosure with a supply of desiccant which maintains an internal environment of 1-50% RH. Desiccant dry cabinets are also called: Desiccators, Dry Boxes, Dehumidifying Cabinets, and Ultra Low Humidity Storage Cabinets.
