Post Production Considerations for ABS Plastic and Nylon Prints
The post-production phase of 3D printing closely considers the finishing and smoothing options available for both ABS plastic prints and nylon prints. For ABS plastic, which is popularly known for being easy to sand and smooth, several methods are applied such as chemical smoothing using a fog of acetone vapor that polishes its surface without losing intricate details. Moreover, vigorous techniques can be used including the application of epoxy coatings or filler primers, filing, grinding, as well as direct engine turning.
- Finishing ABS Plastic: Following an up-close inspection to identify rough patches liberally applying an adhesive in order to fill those areas, after drying it’s sanded off leaving behind a marking compound at low spots. This process, conducted repeatedly until satisfaction, leads to a refined finished product.
- Nylon Finishing Process: On the other hand, nylon printed parts can undergo dyed finishes, making them more versatile in terms of appearance. It’s worth noting that nylon exhibits relative resistance to standard smoothing processes because of its robustness—some users have found that sealing nylon filaments with thin CA glue before sanding can provide some form of efficiency during this part of the procedure. Therefore, treatment with specific substances may enhance the durability of items made from this material. As expected, each method has distinct considerations, leading to different final visual effects and levels of detail retention.
Cost Analysis: ABS Plastic vs. Nylon in 3D Printing
In terms of cost analysis, the use of Acrylonitrile Butadiene Styrene (ABS) plastic and Nylon as materials for 3D printing can greatly affect expenses due to their varying characteristics. Typically, ABS is considered as a more budget-friendly material.
- ABS Plastic: When utilized in 3D printing, ABS generally necessitates fewer overhead costs. The general cost categories associated with its usage primarily include the purchase price, maintenance for the printer, specifically temperature regulation elements considering that ABS requires a high extrusion temperature, and potential waste management fees given the non-biodegradable nature of ABS.
