Recycled Cellulose Polypropylene Composite Feedstocks for Material Extrusion Additive Manufacturing. According to ACS publications,” Many types of consumer-grade packaging can be used in material extrusion additive manufacturing processes, providing a high-value output for waste plastics. However, many of these plastics have reduced mechanical properties and increased warpage/shrinkage compared to those commonly used in three-dimensional (3D) printing. Recycled polypropylene/waste paper, cardboard, and wood flour composites were made using a solid-state shear pulverization process.”

What kind of Problems with LCD Resin 3D Printers. Different ways to fix it? Safety features.

Posted on Updated on

What is your comment?

Please read safety things before using anything –
It is hazardous and it may give you an allergic reaction that you really don’t want (been there still got the skin problem) but it’s not toxic or sometimes it can be. Respiratory Irritation
Breathing highly concentrated epoxy vapor can irritate the respiratory system and cause sensitization. Serious health problems can result from sanding epoxy before it is fully cured. When you inhale these dust particles, they become trapped in the mucous lining of your respiratory system. Because it can cause eye, nose, and throat irritation. And dust from polyurethane resin is highly toxic.
The pure epoxy resins are considered as non-toxic, the risk of damage caused by ingestion of epoxy resin can be considered as very small. Most curing agents in use today have certain toxicity. Inhalation of epoxy resins causes no problems as they are not volatile.
The difference is that SLA works by flashing a laser — a tiny dot of concentrated light — across a given area to harden it and create a layer. In contrast, DLP machines cure all areas of a layer simultaneously, by projecting light onto the resin in the shape of that layer.
We can use liquid resin to produce 3D prints. Since we are dealing with a liquid material, an additional support structure is necessary for overhanging parts and cavities. The average 3D printer material cost for standard SLA resins is approximately $50 per liter. That means entry-level, cheap resins may even be under $50. MakerJuice offers a standard resin for SLA 3D printing, which costs $58 per liter.
Many resins are actually quite toxic, and we wrote on this some time ago. … However, remember that some resins ARE safe, it’s just that many are not – and they should be treated appropriately. The second issue with resin 3D printing is curing, the process that makes the resin solid.

The LCD screen is a consumable item and it is not covered by the warranty on most manufacturers. They are not meant to last forever although I have found that they are very sensitive. You need to strain the resin after every print as any dried resin that is left in the vat will damage the pixels when the next print starts.

@ualdayan I have six resin printers and have been through the rounds. The LCD screen is a consumable. That has been stated to me directly by the manufacturers. If you read the fine print in the warranty you will see that stated as well. The life expectancy of an LCD screen is supposed to be close to 800 hours. I have never gotten close to that.

Great information. LCDs tend to be very temperature sensitive so maybe that is an issue.

As stated by others below, this is to do with UV Exposure and heat. Be wary of ‘high speed’ resins. They have a higher exothermic reaction rate which can also damage the LCD. Using an infrared thermometer i tested ‘AmeraLabs’ AMD-3 LED resin which is a super fast cure resin (2.5 sec per layer at 0.03) and it was curing at nearly 54 degrees Celsius on my mars. When the LCD’s are made they are supposed to have a UV filter film added to lengthen their lifespan which obviously they can’t do for these printers. I’ve had screens last months and screens last weeks. Theres nothing you can do to really affect it other than use standard curing resins that don’t give off as much heat and make sure you do usual checks to make sure your vat and build plate are clean etc etc.

@Dean Rockne As someone that has built PCs…often quieter fans are the better ones actually. Better bearings, lower turbulence, more efficient…all of these make the fan quieter for the same or better cooling.
If heating manages to be a problem, it’d be nearly instant spot heating…which would be practically impossible to cool. Basically, you’d need to chill the resin in the reservoir so that any temperature increase is offset…and I don’t think the resin would respond too well to that. You’re supposed to keep them at room temperature.

It’s a simple problem, the screens are not designed to work with the UV light, product of cheap printers they use cheap screens. You are looking at over $1000USD wholesale for a screen rated for the UV light to fit these printers, that’s a lot of $30 screen replacements.

 

Sand 3D Printer before and now

Posted on Updated on

According to Sculpteo, “Binder Jetting printers spread a layer of the material and then bind it with an agent, which solidifies the particles. A layer for sand 3D printer is 140-200 micrometers.”
According to Markus Kayser,” he talks about ‘desert manufacturing’: a combination of solar power and 3D printing to create objects made entirely out of the sand. As a product designer, he has created a variety of beautiful objects only using the sun and sand.”
According to ExOne’s digital part materialization,” (3D printing) process for printing sand casting molds and cores, beginning with a digital file, going through solidification analysis, printing and finally casting a finished industrial part.”
Comments 4 years ago,
also side topic, I still think bricks made from lava would be a good cheap way to get building materials, you could scoop lava into brick molds with industrial robots and also if you push a magnetic field thru the lave as it cools you could leave a build signature in the structure, that could be used in the future to date and specify where it was made sort of like a bar code but magnetic. but still, lava is still a good material that is underused.
According to AFS MCTV, “I want to see it get to the point where a 3D printer in a desert would be able to print the components for another printer.
This webinar covers the basics of additive manufacturing as well as explains the technology used to create molds and cores with a 3D printer. Led by Dave Rittmeyer and Steve Murray, both of Hoosier Pattern, the webinar will give attendees full access to two industry veterans who have worked in metal casting for a combined 50 years. Attendees will have the opportunity to ask questions, learn from industry experts and see examples of how 3D printed sand has been used within the metal casting industry.”
According to Meimad3, “World’s largest commercial 3D printer (printing volume 4x2x1 meters) – for printing Sand-Cast mold parts for the metal cast.”
According to General Foundry Service, “3d Printed Sand Molds.”
The webinar will cover the basics and explore how to utilize 3D printed sand components on your next project.

You could print big columns in low spots to serve as pilings. Then, you can cap the area with a walking machine so the structure doesn’t get buried. Over time, the additional capped ground will develop a white color which reflects the sun. You could print tunnels and bury them so they stay cool.

Pitt Engineers Receive $1 Million for 3D printed turbine component

Posted on Updated on

Pitt Engineers Receive $1 Million for 3D printed turbine component. The three-year project has received additional support from the University of Pittsburgh ($200,600), resulting in a total grant of $1,003,000.

U.S. Energy Secretary Rick Perry today announced that the Department of Energy will award 113 grants totaling $121 million to 103 small businesses in 29 states.

According to Albert and Dr.Xiayun (Sharon) Zhao, Ph.D., assistant professor of mechanical engineering and materials science at Pitt, “LPBF AM is capable of making complex metal components with the reduced cost of material and time. There is a desire to employ the appealing AM technology to fabricate sophisticated HGPTCs that can withstand higher working temperature for next-generation turbines. However, because there’s a possibility that the components will have porous defects and be prone to detrimental thermomechanical fatigue, it’s critical to have a good quality assurance method before putting them to use. The quality assurance framework we are developing will immensely reduce the cost of testing and quality control and enhance confidence in adopting the LPBF process to fabricate demanding HGPTCs.”
