ABS, or Acrylonitrile Butadiene Styrene, is a popular thermoplastic polymer known for its toughness, impact resistance, durability, versatility, and affordability. It is commonly used in automotive trim pieces because it is strong, inexpensive, and can be easily molded into virtually any shape. However, despite its relatively low melting point, your ABS plastic may not melt because it does not possess a specific melting point. Instead, it softens over a range of temperatures, typically around 105 to 115°C (221 to 239°F), and fully melts between 200°C to 245°C (392°F to 473°F). This range can vary depending on the unique makeup of the ABS and how it is processed. Therefore, it is crucial to understand the melting behavior of ABS plastic to ensure proper processing and avoid overheating or decomposition, which releases carcinogenic chemicals.

Boiling water is a safe method to reshape ABS plastic
ABS has a relatively low melting point, typically ranging from 105 to 115°C (221 to 239°F). However, it does not possess a precise melting point like other materials. Instead, it softens over a range of temperatures. At temperatures slightly below its melting point, ABS becomes very flexible without melting.
Using boiling water to reshape ABS plastic is a common and safe method. Boiling water allows the ABS to be heated enough to become easily shapable and mouldable, but it prevents the plastic from exceeding 212°F (100°C) no matter how long it is submerged. This reduces the risk of accidentally overheating the ABS, which can lead to burning or decomposition, releasing harmful chemicals.
By dipping the ABS into boiling water, you can safely soften and mould it without any risk of melting. This method is simple, easy to do, and provides flexibility in reshaping ABS plastic parts to fit your desired applications.
However, it is important to note that simply dipping the ABS into boiling water may not be sufficient to reshape it effectively. Some sources suggest that the entire ABS part should be immersed so that the entirety of the part reaches temperatures above 100°C for optimal reshaping. Additionally, when working with ABS plastic, it is recommended to wear appropriate personal protective equipment and ensure proper ventilation to avoid any potential health risks.

ABS plastic has a relatively low melting point and melts easily, but it does not possess a specific melting point. Instead, it softens over a range of temperatures, typically around 105 to 115°C (221 to 239°F) or 93°C to 121°C according to other sources. This is the temperature range where ABS starts to lose its rigidity and become more pliable. The softening temperature of ABS plastic is also known as the Vicat Softening Temperature (VST).
When it comes to actual melting, ABS transitions into a more fluid state at a higher temperature. In 3D printing, the recommended extruder temperature for ABS filament typically falls between 220°C and 250°C (428°F to 482°F). The build plate or bed temperature often ranges from 80°C to 110°C (176°F to 230°F). If the temperature is too low, the plastic may not flow properly, leading to weak or incomplete prints.
It is important to control the temperature carefully when heating ABS plastic to avoid overheating or melting it. A common and safe method of reshaping ABS plastic is to use boiling water, which prevents the plastic from exceeding 212°F (100°C) no matter how long it is submerged. Heating ABS over an open flame or other direct heat source risks heating the plastic to the point where it decomposes, releasing carcinogenic chemicals.
