The Key to Repeatable 3D Printing? Materials
The latest issue of Additive Manufacturing Magazine explores how materials will be the key to production 3D printing.
Developing, testing and manufacturing materials for 3D printing will be necessary to advance the technology into full-scale production.
Both Modern Machine Shop and sister publication Additive Manufacturing have covered plenty of examples where 3D printing is being used to manufacture real, end use parts. It is already being applied to manufacture jet engine parts, medical implants, milling tools, rockets and more.
But what’s holding additive manufacturing (AM) back from its holy grail, full-scale production? One of the biggest hurdles to overcome is materials. Reliable materials, with proven print profiles, will be needed — in adequate quantities — if AM is to reach this next stage.
The September issue explores how materials will enable production via additive manufacturing.
The September/October issue of Additive Manufacturing Magazine details how various organizations who recognize this challenge are dealing with it. Stories in this issue include:
- Research by the National Institute for Aviation Research (NAIR) to build out a database of materials and process information for AM.
- How Jabil, one of the world’s largest contract manufacturers, is not only developing new 3D printing materials but working to ensure a reliable supply chain for mass production.
- Evidence that 3D printed polymer parts can outperform molded ones for a common requirement.
- A hybrid manufacturing strategy that combines an unusual material, topology optimization and interlayer laser peening.
- Recommendations for improving operator safety in the face of emissions from polymer 3D printing.
Analyzing directed energy deposition and powder-bed fusion provides a thorough understanding of the extra machining necessary for a “near net shape” versus a “net shape” manufacturing process.
An engineering modification that would have been impractical or cost-prohibitive in the past is realized on a machine tool performing metal 3D printing and machining in the same cycle.
A new metal AM system for batches of end-use parts was designed to permit productivity and machine pricing comparable to a CNC machine tool.
