Manufacturing notes
Read practical notes on CNC machining services, injection molding services, additive manufacturing, tooling, inspection planning, material certificates, and DFM decisions that affect regulated part programs.
A quality manager’s story about a $14K automotive mold reject, the risk of switching to digital manufacturing, and where CNC automotive parts, aluminum extrusions, and ProtoLabs actually fit.
Continue ReadingPractical answers to real questions about ordering precision machined components, from CNC stainless steel parts to forged steel flanges and metal Y connectors—written by someone who actually places the orders.
Continue ReadingA procurement manager's take on ProtoLabs injection molding cost, TCO, and when to choose 3D printing, desktop CNC, or local machining.
Continue ReadingBefore you request a ProtoLabs quote, figure out which of these three scenarios you're actually in. A procurement manager breaks down when ProtoLabs makes sense, when it doesn't, and how to calculate the real total cost.
Continue ReadingA production manager's story of a rush order gone wrong, the hidden cost of 'probably on time' promises, and why paying a premium for guaranteed delivery is usually the cheapest option.
Continue ReadingA procurement manager breaks down the real cost comparison between ProtoLabs and traditional machine shops for CNC machining, injection molding, and industrial parts — including the hidden costs nobody quotes upfront.
Continue ReadingHow to choose between ProtoLabs metal 3D printing and a CNC milling factory. A quality inspector explains when to use the ProtoLabs instant quote and what hidden costs to check before comparing prices.
Continue ReadingAfter managing a $180,000 prototyping budget, a procurement manager explains when to use the ProtoLabs injection molding contact email, where ProtoLabs CNC machining fits, how a fiber laser cutting machine works, and why quote jargon can hide cost.
Continue ReadingOur engineering manager wanted a Brother Speedio machining center. I wanted to see the total cost of a VMC installation next to a ProtoLabs order. Here’s how the two options compare for a non-machinist, buyer-focused team.
Continue ReadingA mechanical engineer explains why reading reviews is not the best way to choose a 3D printer, then shares six pre-order checks for every ProtoLabs 3D printing job.
