According to Science News and John Canning who led the research team from the University of Technology in Sydney, “Making silica optical fiber involves the labor-intensive process of spinning tubes on a lathe, which requires the fiber’s core or cores to be precisely centered. With additive manufacturing, there’s no need for the fiber geometry to be centered. This removes one of the greatest limitations in fiber design and greatly reduces the cost of fiber manufacturing.
Additive manufacturing approaches such as 3D printing are well suited to change the entire approach to fiber design and purpose. This could, for example, broaden the applications of fiber optic sensors, which far outperform electronic equivalents in terms of longevity, calibration and maintenance but haven’t been widely deployed due to their expensive fabrication.”
Awesome to be green:)
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.
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?
#1 plastics: PET or PETE (polyethylene terephthalate)(Is it safe? -No) #2plastics: HDPE (high-density polyethylene)(Is it safe?- YES)
#3 plastics: PVC (polyvinyl chloride or plasticized polyvinyl chloride)(Is it safe?- NO)
#4plastics: LDPE (low-density polyethylene)(Is it safe?-YES)
#5 plastics: PP (polypropylene)(Is it safe?- YES)
#6 plastics: PS (polystyrene)(Is it safe?-NO)
#7plastics: other (all other plastics, including acrylic and nylon)(Is it safe?- NOT SURE)
If you want to reuse any material
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.
