The CAMT exam has 110 questions and runs 3 hours.
These 10 free CAMT questions are organized by exam domain, so you can see how each part of the Certified Additive Manufacturing Technician blueprint is tested. Reveal the answer and explanation under each question.
A customer's drawing calls out a metal with a high strength-to-weight ratio and proven biocompatibility, because an implantable variant of the same part is planned. Which material meets both requirements?
Correct answer: C - Ti-6Al-4V
A technician removes parts from the build plate, takes off the supports, and sends the parts out to be measured on a CMM. The parts are then painted before shipping. Within the AM process chain, painting belongs to which step?
Correct answer: A - Secondary Processing
A machine builds parts by selectively depositing a liquid bonding agent onto successive layers of powder. Parts leave the machine intact but chalky and fragile, and must go through a furnace cycle before they can be used. Which process category is this?
Correct answer: D - Binder jetting
CT scanning of a laser powder bed fusion part reveals rounded pores concentrated deep within the melt tracks. Laser power was raised the previous week to shorten build times. What is the MOST likely cause?
Correct answer: A - Keyhole porosity
All of the following are listed as disadvantages of additive manufacturing **EXCEPT:**
Correct answer: C - Mass customization
A design team supplies an STL file for a consumer product that must be printed in three colors on a material jetting machine. The geometry is correct and the mesh is watertight. Why is the file still inadequate?
Correct answer: C - STL carries no color or material information
An imported model reports edges shared by three faces and several surface normals pointing inward. Within the data preparation sequence, which step addresses these conditions?
Correct answer: B - Model repair
A cylindrical FFF part will be loaded in tension along its axis in service. A technician lays it flat so that the cylinder axis runs parallel to the build platform. What is the PRIMARY consequence of this orientation?
Correct answer: A - The load will be carried across the layer bonds rather than within them
A supervisor wants to know whether part density has been drifting across the last forty builds of the same component. Which post-build data management activity supports this?
Correct answer: D - Statistical process control
A foundry prints wax patterns that are invested in a ceramic shell and then melted out to leave a cavity. The pattern does not survive the process. This pattern is classified as:
Correct answer: B - Sacrificial tooling
