Every RP article implies that faster design processes are better. Here the author even argues that more iterations leads to better outcomes. This may sound obvious, but anyone involved in design will tell you: faster doesn't always mean better. Here is a hint: it really depends on the design methods that you use and how far in the decision making process you are. Sadly, the last 10 yrs have shown me that most RP are not actual improvements to the quality and originality of products. Some times faster just means faster, and this only means producing crap designs faster than before.
Thanks for raising the issue, SoCalPE, and thanks Jason, for the link to a resource for suggestions on plastic part disposal. I'm sure we'll be hearing a lot more people raising concerns about this issue as 3D printer use becomes more prevelant and as more organizations more widely integrate the technology as part of their prototyping and product development workflows.
On i.materialize, the first search result from above, they lay out 4 possible solutions. While they may not work for everyone and every 3D printer, they are atleast bringing some interesting and valid means or reusing unwanted printed objects.
Beth, thanks for corroborating my concerns about recycling 3d printed parts. Yes, that photo with the caption "... generate a mountain of throwaway prototypes..." is concerning in our society's semi-enlightened path of renewal ability and recycling. I'm an avid fan and user of FDM 3d printing for prototype parts. To my knowledge, SLA material cannot be recycled unlike 3d printers that extrude ABS (which we recycle after the parts are tested). I'm not sure about Objet or ZCorp parts. Doug, can you speak to this?
P.S. Tape Wrangler tolerances of some parts are 1/250,000 of an inch. Really???
Great working examples of how 3D printers are being used in companies to faciliate design and as a more cost-effective means of prototyping.
Seeing that image of all of those plastic, 3D printed parts, though, makes me think about disposal issues related to all this content that will be generated. A reader raised that issue in a comments on another 3D printer story and that image really brings the concern to light.
Last week, the bill for reforming chemical regulation, the TSCA Modernization Act of 2015, passed the House. If it or a similar bill becomes law, the effects on cost and availability of adhesives and plastics incorporating these substances are not yet clear.
The latest crop of coating and sealant materials and devices has impressive credentials. Many are designed for tough environments with broad operating temperature ranges, and they often cure faster, require fewer process steps, and produce less waste.
A new program has been proposed for testing and certify 3D printing filaments for emissions safety. To engineers who've used 3D printers at home this is a no-brainer. It's from a consumer on Kickstarter, and targets use in homes and schools.
For the last 50 years, the Metal Powder Industries Federation (MPIF) has sponsored an awards competition for creative solutions to designing and fabricating near-net-shape parts using powder metal (PM) technologies. Here are the seven Grand Prize winners of the 2015 contest.
Graphene 3D Lab has added graphene to 3DP PLA filament to strengthen the material and add conductivity to prints made with it. The material can be used to 3D print conductive traces embedded in 3D-printed parts for electronics, as well as capacitive touch sensors.
