A trauma fixation RFQ usually bundles several different part types into one project: a contoured plate, a run of bone screws, sometimes an external fixation component. Reviewing them as one manufacturing decision is where a plan goes wrong. Each part family in Lab Ready's trauma device manufacturing scope drives a different process, tolerance and finish route, and the RFQ should reflect that from the start.

Plates, screws and external hardware are different machining problems

A fixation plate is a contoured, multi-face part where hole pattern, contour and mating surfaces all need to relate back to clear datums, which is why feature-to-datum control is the first thing to lock down before machining starts. A bone screw is rotational geometry: shaft, thread and drive feature generated by turning the stock rather than milling around it, which is the same distinction covered in more depth in CNC turning for orthopedic implant components. External fixation hardware and drill or placement guides are a third family again, often lower-quantity and validation-stage rather than a repeat production run. Treating all three as "trauma hardware" without separating them by geometry is how a quote ends up over-specified on the easy features and under-specified on the ones that actually control fit.

Choosing between CNC machining and metal 3D printing

CNC machining is the direct route for most plates, screws and standard fixation features, using 3, 4 and 5-axis milling for contoured geometry and turning or Swiss turning for rotational parts. DMLS or SLM metal 3D printing can fit more complex, lower-quantity trauma geometry, with post-machining coordinated afterward for any interface that needs tighter control than the as-printed surface provides. The same process-selection logic covered in DMLS vs. CNC machining for orthopedic parts applies here: geometry and quantity should decide the route, not a default assumption that one process covers the whole part family.

Threads, finish and inspection belong in the RFQ, not after it

Thread form and gauging matter enough on a bone screw that they should be specified alongside the drawing, not treated as a downstream detail. Edge condition, bead blasting, passivation, polishing or coating requirements can each change how the underlying part is machined or printed, so naming the finish at quote stage keeps the manufacturing plan and the final inspection aligned instead of working backward from a part that already exists.

What to send with a trauma fixation RFQ

Alloy and grade should reference the full titanium and stainless options already listed on the materials page rather than a generic "titanium or stainless" note; for example, Titanium Grade 5 (Ti-6Al-4V) and 17-4 PH stainless are both already-published grades relevant to fixation hardware, and the specific grade, condition and heat-treatment state should be stated up front. Beyond alloy, a complete RFQ should include the part family (plate, screw, external fixation, guide), critical datums and tolerances, thread details, finish, inspection needs and target date.

Send the drawing along with the alloy and grade, thread and finish requirements, quantity and target date through Lab Ready's contact page, or start from the RFQ checklist if the part family or process route is still open.
