ABS vs. MDF
ABS belongs to the thermoplastics classification, while MDF belongs to the wood-based materials. There are 11 material properties with values for both materials. Properties with values for just one material (13, in this case) are not shown.
For each property being compared, the top bar is ABS and the bottom bar is MDF.
