Parts often require a post-curing operation in a separate oven-like apparatus for complete cure and stability.
Supports must be removed from part.

ABS is a common end-use thermoplastic material with considerable durability. This material is ideal for a variety of modeling and prototyping activities due to its stiffness and ease of finishing.
ABS Materials Specifications:
Tensile Strength 5,000 psi
Tensile Modulus 360,000 psi
Flexural Strength 9,500 psi
Rockwell Hardness R105
Vicat Softening Point 220 (v)
Specific Gravity 1.05 g/cc
This tough, rigid, high-strength thermoplastic has a heat deflection temperature of 343°F (174°C), and maintains its properties over a wide temperature range. Transparent, opaque and glass-fiber reinforced grades are available.FDM MATERIALS

Build metal parts and tools directly. We have experienced some impressive progress throughout the past few years, but many would argue that the development of machines that produce metal parts leaves room for improvement.
Accept smooth surface data from the CAD systems. RP systems still do not accept mathematically smooth surface data. Fortunately, the cost and performance of desktop computers have improved so much that it is no longer a problem to reduce the triangular facet size in STL models to the point at which the surfaces appear smooth.
RP vendors must become fiscally sound. Today, most companies in the business of manufacturing RP systems continue to struggle.
Improve the price/performance ratio. Vendors continue to introduce new machines that give customers a bigger bang for the buck. Many customer prospects have voiced their views on the idea of a low-cost machine. To some, low cost means $20,000. To others, it means $2,000. We have yet to reach either milestone, although we are closing in on the first one.Obstacles Yet to Overcome for RP
