Product Information

Unwanted Food or Drink Products - Once supply conditions are broken, there are a number of factors outside of our control that can affect the quality of a product. Therefore perishable goods such as food and drink cannot be returned. The following photograph shows what happens to a part when exposed to the fumes for an extended period.

You will walk away, forget it, only to return later to find that amazing print that you were once so proud of has now turned into a hideous misshapen lump of plastic, or at worst some kind of acetone ABS mess. Polishing tips: Use an accurate thermometer, a convection oven, and an oven-safe surface. Do not open the oven door during polishing. Expect some shrinkage and growth along the print axes. We want to melt the surface of the object just enough that the surface tension of the molten plastic smooths out any surface inconsistencies and then halt the process at that point before any structural damage occurs. Acetone vapor baths are one of the most popular and reliable ways to get a smooth finish in 3D prints. What is the principle behind this process? How is it done? Read on for our comprehensive guide on acetone vapor baths. What filament materials can be smoothed using an acetone vapor bath? Before continuing further, please make sure you acquaint yourself with the safety regulations pertaining to acetone (propan-2-one) and its use. It is your responsibility to use this solvent safely.

Once you are satisfied that the polishing is almost complete, carefully remove the object to a totally dust-free environment that has good ventilation. This stops most of the ever-present dust particles that are suspended in the air from falling onto the semi-molten surface of the object.

The bad news is that acetone vapor baths don’t work for all types of 3D printing filaments. On the flip side, an acetone vapor bath is the perfect smoothing solution for the super-popular ABS. There are also other filaments that work well with acetone, including HIPS, PMMA, ASA, and Polycarbonate. The polishing process continues for a while after you remove the object from the container – usually for about ten minutes. So don’t be tempted to leave it in too long.Acetone polishing or smoothing is a safe and easy method of 3D print finishing for smoothing out surface inconsistencies without causing structural damage. Stuff the paper towel on the bottom of the drinking glass, ensuring a snug fit, so it does not fall off when you turn the glass over. Pour the acetone into the paper towel, just enough so that the paper towel is completely wet but not soaking. Turn the drinking glass over the plastic tray, completely enveloping the print atop the metal platform. To simplify the discussion, let’s assume that we are working only with an ABS print. ABS is highly soluble in acetone. In fact, dissolving ABS in acetone is how you get ABS glue. The idea of immersing your ABS print in acetone vapor is for the outermost layer of the print to dissolve, effectively hiding the imperfections of the original print. Remove the object from your dust-free chamber without touching it, and put it somewhere that has good ventilation to allow the acetone to further leach out of the object. The object at this point has little to no structural integrity so be careful how you do this.
