Adding glass to sintered nylon roughly doubles tensile modulus and lifts heat deflection sharply, while cutting elongation at break by more than half and adding a third to the density. Here is when that trade pays.
Anyone quoting a universal breakeven quantity is guessing. Here is how the two cost curves actually behave, what moves the crossover, and how to work out your own.
When a product leaks air faster than the pump can pull it, vacuum stops working. Needle grippers solve that by penetrating instead of sealing, and the trade-off is a mark you have to design around.
A true living hinge depends on molecular orientation that injection moulding creates and sintering cannot. Here is what a printed PA12 flexure can realistically do, and how to design it.
What the real minimum wall thickness is for laser sintering, why the recommended range sits above it, and why most thin wall failures happen during depowdering rather than in service.
On a tray loading cell the pick count drives the tool, not the payload. How multi-pick arrays are sized, why pitch matching constrains the design, and why more cups does not mean more holding force.
Delrin is stiffer and slipperier, nylon is tougher and printable. A datasheet-level comparison of acetal and polyamide for robot tooling, and how the manufacturing process decides as much as the material.
Heat set inserts put a durable metal thread into a sintered nylon part. How to size the boss, how installation actually works, what fails when it fails, and the alternatives worth considering.
Metal additive manufacturing carries cost in places the quote does not always show. Here is the real cost structure, and the honest test for when a sintered nylon part replaces a metal one.
On a depalletizing cell the pallet arrives as it arrives, so the load pattern drives the tooling. How layer picking, mixed SKU loads and slip sheets change end-of-arm tool design.
Polyamide and nylon are two names for the same family of polymers. What the PA numbers mean, how PA6, PA11, PA12 and PA66 differ, and which grade belongs in a printed production part.
A vacuum switch turns the vacuum level in a gripper circuit into a pick confirmation signal. How setpoints, hysteresis, sensing location and zoning decide whether EOAT catches a failed pick.
