Taking the first example: there could, for instance, be some residue of another powder left on the build plate, leading to the blending of two different powders. However, there are several ways in which metal powders can become contaminated.įor example, the risk of contamination can arise during the printing process itself or during storage, transportation and handling. Impurities can alter the properties of the final part which could, in turn, lead to a failed print. This is especially the case for safety-critical applications, such as aircraft parts or medical devices, where the material used must be 100% free of contamination. One factor complicating the process is the need to maintain the purity of metal powders used for additive manufacturing. ![]() ![]() However, material qualification is an ongoing challenge for companies producing or handling metal powders. Today’s article will be looking at the some of the key challenges companies face when trying to establish QA processes for metal 3D-printed parts and explore some of the solutions available.Ĭhallenge 1: Ensuring the quality of your materialsĮnsuring that a 3D-printed part meets the standards of highly demanding applications heavily depends on the quality of the material used. When it comes to metal 3D printing, however, this has been an ongoing challenge for many manufacturers looking to invest in the technology. With 3D printing being increasingly used in high-performance industrial applications, the technology must consistently and reliably deliver high-quality parts with the properties needed to meet demanding applications. Detailed instructions can be found at: then click on 4-H Youth Development tab then click on 4-H Forms tab.Quality assurance (QA) is arguably the most important and yet one of the most challenging steps in 3D printing. Youth are strongly encouraged to print or save the pdf certificate for proof of participation. Youth who successfully complete the entire certification must email the certificate in pdf format to verification purposes. If a youth fails a quiz, they can wait and retake the section. Each training module contains three sections and a quiz for each section must be passed to receive certification. Website is Youth must participate in the training module based on their current 4-H age (age as of ). This opportunity is available to youth at a cost of $12 per participant and can be taken whenever you are able to access the internet. ***Youth can participate in the online QA, anytime with Youth for the Quality Care of Animals (YQCA) web-based certification. Final dates to complete QA Training or Test-out: If exhibition at the Ohio State Fair is before their county fair, youth must have completed that training at least 45 days prior to exhibition at the Ohio State Fair. This includes youth exhibiting at the Ohio State Fair. QA Certification must be completed at least 45 days prior to the start of exhibition. **Please do not use a school email – it will not let us send you an email with the link. The zoom link will be emailed the night before the scheduled Zoom. You will not get a confirmation from this sign-up. ![]() ** OR CALL NANCY SNOOK at 74 and she will sign you up.
