This blog is the second in our series on technical printing. In our first blog we gave an in-depth description of what technical printing is. In this blog, we will talk about how technical printing projects go from development to production.
How are technical printing projects started? At GM Nameplate (GMN), technical printing projects start in our development department. Here the design is scrutinized, reviewed, and tested. The goal is to produce development part designs and find out quickly whether the part is manufacturable or not. This department will provide design considerations and test reports until a conclusion is drawn. Once a batch of parts has a high yield per volume and a high success rate, the project can move onto full production.
There are five phases that technical printing projects go through during development before it can move on to full-scale production, each one with specific operations. These phases are particular to technical printing projects only because of the high level of scrutiny required in development.
Phase 1: Ideation
Ideation is an ongoing conversation between the customer and GMN to identify the areas of highest design risk. This allows both parties to define steps to test design assumptions and evaluate potential design and material solutions to help build confidence about the known challenges.
Phase 2: Risk mitigation
This phase is used to validate material stability and printability, explore material handling and registration options, review curing processes, and establish a planned production approach. Defining the risks and challenges that are likely to occur allows for a plan to be made accordingly. All challenges must be addressed with extreme scrutiny because technical printed parts require much tighter tolerances.
Phase 3: Low volume functional prototyping
Low-volume prototyping is used to create functional printed parts using the materials and preliminary product design planned for use during full volume production. This could take several rounds of prototype layouts and testing, and repeating this process until a high yield success rate is achieved. With technical printing, projects in this phase become more device-specific and are outside of typical production, development, and industry standards.
Phase 4: Production development prototyping
With a suitable design identified, GMN will work on transitioning into production manufacturing development. Larger quantities of parts will be printed and evaluated, with the goal of meeting customer specifications. The parameter window for meeting the customer’s specifications is very small in technical printing, and is why technically printed parts are evaluated so thoroughly.
Phase 5: Production validation
Once the parts have passed the previous phase, the project is handed to a production team and design engineer to apply to production volume quantities.
GMN’s expertise and strict quality systems allow us to work in these highly regulated spaces and gives our clients confidence in the parts we produce for them.
