3D PRINTING FACTS
A work in progress timeline of the history and evolution of 3D printing
Dr Hideo Kodama of the Nagoya Municipal Industrial Research Institute invented a method of fabricating 3D plastic models with photo-hardening thermoset polymer using cross-sectional slices of layers on top of each other. He filed a patent for this XYZ plotter in 1981. Due to lack of commercial interest however, the project was abandoned and the patent was never acquired!
The first Stereolithography Apparatus (SLA) machine is invented by Charles Hull. Hull’s invention led to the rapid development of additive manufacturing.
The first 3D printing patent in history is filed in 1984. The Computer Automated Manufacturing Process and System patent is the first of 3 patents filed by American entrepreneur Bill Masters who thus laid the foundation for the 3D printing systems used today.
Carl Deckard at the University of Texas filed a patent for Selective Laser Sintering (SLS) technology. SLS used a laser to trace and solidify layers of powder polymers. This innovative new technology was then leased to DTM INC for commercial use.
Fused Deposition Modeling (FDM) technology is invented and patented by S. Scott Crump. FDM is one of today’s prominent additive manufacturing technologies.
Emanuel Sachs, Professor of Mechanical Engineering at MIT, invented a process where an inkjet printhead selectively drops a liquid binder material into a powder bed thus creating a three-dimensional object layer by layer. Sachs coined a new name for this process: 3D printing.
3D PRINTING TIPS
When we embarked on our exciting 3D printing journey (and we are still novices, mind you!), we faced many challenges that we have had to overcome, many problems to solve. What follows is a collection of troubleshooting tips and advice that we think you might find helpful, if you are interested in the 3D printing process. Most of these we have already posted on our social media and we will keep adding to the list, so be sure to check in regularly or, better yet, follow us there to stay up-to-date!
- If the first layer is not sticking to the printer bed print your first layer at a low speed to give the material time to bond to the printing platform. If this doesn't work, check if the nozzle starts at the proper height relative to the printer's bed. these settings are easily adjustable.
- Take care of your filaments. Most of these pals are hydrophilic & capture moisture with a high possibility to expand during extrusion. Try to dry damp filaments in the oven at low temperature for 2 hours
- How to fix a weak infill: If your 3D printed part appears to have a weak infill, lower your 3D printing speed or increase the infill width.
- When to add supports to a 3D printed model: Sometimes a layer does not stack accurately on the previous printed layer due to a small offset. It is helpful to remember that below 45 degrees overhang features can be supported by the previous layers. Anything beyond this point will require support.
- How to fix printing gaps: Gaps in 3D print models are usually due to over-extrusion or under-extrusion. The first thing to review is the flow rate. Readjust the rate slowly while checking the result by running quick prints.
- How to solve an overheating problem: Make sure that the cooling fan works properly. Then reduce the printing temperature by 5-10°C. If the problem persists, lower the printing speed to allow time for the deposited layer to cool down.
- How to avoid layer shifting: Reduce your 3D printing speed by 30-40% & print again. If that doesn't work, set the speed to the default setting. If that doesn't work either, check the tension of the belts that control the printhead position.
- Did you know that vacuum casting is an efficient way to produce small batches of high quality complex parts? It is also much more affordable compared to other casting methods.
