Build Ups to Avoid about 3D Printing and 3D Printers

3d printing is a most progressive in the field of manufacturing, engineering and other industrials. All the hype around the 3d printer in which we are currently seeing is partially true. Please remember 3d printing is still in its early stage and it is not fit for complete usable product to all categories people around the world.

3d printer hype

 

Here are some common build ups to avoid about 3d printing:

 

  • 3d printer price is very costly and not affordable. You can’t make accurately things possible.

  • CAD 3d modelling techniques are very complex and hard to learn.

  • It will take months and years to learn CAD to design complex 3d structures.

  • 3d printed things which is shown in the news are all not real some of them are much exaggerated and they are not functional actually.

  • You can 3d print organs too and but have doubts whether they are working and really save lives.

  • Most of the personal desktop 3d printers are not reliable and original when comparing to the other electronics in the market.

  • Accuracy, surface quality, strength, and colour of 3d printed samples are not enough for most applications.

  • Post processing refers that there will be more work involvement.

  • Industrial 3d printers are not up to the mark, it is very slow, costlier, portable and not usable enough.

  • Many industrial operations handling processes such as conveyor belts and de powdering of samples have not been applied to 3d printers.

  • 3D Printing in metals is very important in this concept and it is very rare.

  • Material costs are ridiculously high, inhibiting 3D printing development.

  • Much of the analysis coming out by stock and other people about 3D printing is not based on any real understanding of the technology and is quite frankly hilarious.

  • 3D printing is a collection of many different technologies all better or worse at making various things.

  • We are not collectively developing a Star Trek Replicator at the moment. Company A is making a machine to make tea at home, Company B tea in the workplace, Company C is doing coffee etc.

  • Why will everyone have a desktop 3D printer? We don’t all use our own sewing machines to make our own clothes.

  • There is no common parts infrastructure for 3D printer parts. No wide spread motherboard, CPU or case ecosystem.

  • We don’t have a postscript for 3D printing so “your 3D printed files are like a box of chocolates.”

  • There is no closed loop control on industrial machines or processes which means that your aircraft part is currently also “like a box of chocolates.”

  • Mainstream 3D printing materials such as SLS and SLA degrade due to UV degradation making parts ugly and brittle after a year in the sun.

  • The only 3D printing process that is food safe is ceramics.

  • Many industrial 3D printing materials are proprietary and one has no idea what is in them.

  • 3D printing is developing much slower than you think. Because you’ve been exposed to a lot of technologies in a short time frame it seems as it is going faster than it is.

  • I made a 3D printing presentation in 2008 and only had to change two slides to use it recently. Try that in the internet or mobile world.

  • Of every ten news stories that come out on 3D printing roughly a quarter contain factual errors.

  • Many of the “3D printing organs” stories have not been based on publicly available research but rather are funding requests via the media.

  • Repeatability of 3D printing parts is very low when compared to traditional mass manufacturing technologies.

  • Many nice and shiny 3D printed parts you’ve seen on TV require hours of post-processing to get them to look that way.

  • At the very least, 3D printing Kickstarter projects have been pure fantasy.

  • There are still no functional 3D printed shoes available, despite of what you may have heard.

  • The “3D printing revolution” is a savvy rebranding of a decades old technology through social media and extensive spending on PR.
