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.”

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.

Is a sand 3D printer the future of Additive Manufacturing?

3D printing technology to be fully Eco-friendly.3D printing technology uses large amounts of energy, larger than the amount used by milling and drilling machines.
If you think about failed prints you may somehow eventually recycle the plastic.
Plastics products may take up to a thousand years to compost while PLA products compost within 3-6 months in a composting system.
PLA-  is made from renewable sources, such as starch – corn, potatoes, soy protein, cellulose, and lactic acid, cassava, sugarcane or sugar beet pulp, all of them are compostable, but this process is only considered “composted” The material breaks down into carbon dioxide, water, and biomass.
3D printing waste happens –

when sometimes layers aren’t sticking together properly in mid-print and depending on the model’s geometry it might cause a failure.
This could be because you’re 3D printing at a temperature that’s a bit too low.
Precaution-

Increase the print temperature slightly and ensure those layers fuse into each other.
In 3D printing, two most common filaments to print with are ABS plastic, PLA, polyamide (nylon), glass filled polyamide, stereolithography materials (epoxy resins), silver, titanium, steel, wax, photopolymers, and polycarbonate.
3D printing uses sustainable manufacturing method. Because it reduces waste.
Later its applications range from medical devices to aerospace — and possibly even drinking water.
ABS – is a thermoplastic that is great for 3D printing because of its strength and durability. This material is not biodegradable or compostable but can be recycled.
ABS (Acrylonitrile Butadiene Styrene), which Lego is made from, is a safe plastic. BabyBjorn also uses ABS – it’s BPA free. Plastics made from corn starch resin are lumped into the #7 category, and these are BPA free too.
Nylon –  is BPA free, and it’s a #7.
These numbers are for which plastics are healthier for you and more easily recyclable?

4 Ways to Recycle Failed 3D Prints

What do the numbers on plastics mean?

#1 plastics: PET or PETE (polyethylene terephthalate)(Is it safe? -No)
#2 plastics: HDPE (high-density polyethylene)(Is it safe?- YES)

#3 plastics: PVC (polyvinyl chloride or plasticized polyvinyl chloride)(Is it safe?- NO)

#4 plastics: LDPE (low-density polyethylene)(Is it safe?-YES)

#5 plastics: PP (polypropylene)(Is it safe?- YES)

#6 plastics: PS (polystyrene)(Is it safe?-NO)

#7 plastics: other (all other plastics, including acrylic and nylon)(Is it safe?- NOT SURE)

If you want to reuse any material

Use precautions-

can re-heat the material to use it again in a filament recycler.
If we like to do some craftwork, get a ‘ProtoCycler’ and make your filament.

ProtoCycler+
ReDeTec Protocycler – OMG it works!

This kind recycler will smash failed prints into smaller pieces, melt them down, and force the liquid plastic through an opening.

The World’s First Zero-Waste Fully Customizable 3D-Printed Skirt

Posted on Updated on

According to Julia Daviy, “the World’s First Zero-Waste Fully Customizable 3D-Printed Skirt. The days of 3D printing being a hyped-up novelty are gone. The technology has moved past the innovation stage and is well into the early adoption phase as more and more people seek out information and dip their toes into the industry. But while 3D printing as a whole is rapidly becoming more mainstream, when it comes to printing clothing, there are still major challenges”.
