Got Milk? Then You’ve Got 3D Printer Filament at a 99.7% Discount

According to a new study produced by the Pearce Research Group at Michigan Technological University (MTU) you can now save yourself money and help the environment, all while making sure you have strong bones. It turns out that the plastic milk jugs used in many countries are actually more efficiently recycled into filament for 3D printers than into plastic for reuse. When the High Density Polyethylene (HDP) milk containers are recycled in traditional facilities, the energy consumed to make the material reusable is considerably greater than that which is consumed when they are processed to make filament in the comfort of your own home.

3D Printed Blow Molds Perfect for Short Run Packaging Production

Plastic packaging is a common part of everyday life: bottles; containers for foods, beverages, medicines and more fill our pantry shelves and recycling bins. Thin-walled and hollow plastic bottles (later filled with the customer’s product) are made on a large scale with a process called blow molding, where hot air is blasted into a precisely calibrated metal mold, and the waiting thermoplastic assumes the shape of the mold. Because of the heat and pressure inherent in the blow molding process, large-scale production requires traditionally machined metal molds. However, for short turns, the molds can actually be 3D printed using PolyJet-based 3D printing technology from Stratasys.

Cost-effective Blow Mold Prototypes with 3D Printing

Blow molding is a manufacturing process used to produce hollow plastic parts, such as bottles and other containers. Blow mold design and the specification of process parameters require skill and precision. A small change in the pinch–off or vent design, die temperature or blow pressure can dramatically affect the molding results.

Prototyping enables designers to validate these parameters and accelerate design approval. But up till now, high costs and long lead times have deterred blow mold prototyping.

Additive manufacturing, or 3D printing, makes prototyping a viable option. In this brief video you will learn how to produce cost-effective blow molds using PolyJet-based 3D printing from Stratasys.

3DPonics Launches Their Free Design for a 3D-Printable Hydroponics System

If you are like me, you love fruits and vegetables, but don’t love the increasing prices for produce, which go up seemingly every few months. It can literally cost hundreds of dollars per month to purchase enough produce to feed a family of four, especially in larger cities where space for farming and personal gardening are limited. Not everyone can have a farm in their backyard… until recently.

3Dponics – Free 3D-Printable Hydroponics System – Recycle Old Bottles is a free 3D-Printable Hydroponics System
For less than just one penny a day, you can: grow your own fresh, organic foods and do something good for the environment by recycling plastic bottles; reduce food waste by picking only what you’ll consume; and do so even in a small city apartment. It can all be done using 3Dponics.
Using 3D-printed parts and recyclable bottles, we’ve created an open source hydroponics system called 3Dponics.
It’s eco-friendly, low-maintenance, energy-efficient, local and, best of all, FREE! You start growing your own organic produce—eat, sell or trade what you grow. We’ll provide you with the 3D-printed components you’ll need to set your system up. Once you’ve got the parts, setting up is super simple, and we provide step-by-step instructions on our website
3Dponics is a 3D-printed hydroponics system that allows you to grow your own food, follow a healthy lifestyle, support local agriculture and do something good for the environment. The system is perfect for growing tomatoes, cucumbers, peppers, lettuce, microgreens, herbs, strawberries and even flowers.
You’ll always have the freshest produce within reach, and best of all, you’re in control of what goes into your food-no more worrying about toxic pesticides, herbicides and other harmful chemicals.
Other components, which are not 3D-printed but can be easily sourced, include:
-Three or four empty plastic bottles (1 L or 2 L recommended)
-Hagen Marina 200 quiet aquarium air pump (*or equivalent)
-10 ft of aquarium air pump tubing
– 20 zip ties

India’s ProtoPrint Makes Fair Trade Recycled 3D Printer Filament

Though 3D printing boasts the ability to save material by building objects up layer by layer, instead of cutting them out of solid blocks, numerous participants in the 3D printing industry have noted the abundant waste of plastic involved in the technology.

3D Systems, Coke & Team up For EKOCYCLE Cube 3D Printer – Uses Recycled Bottles

This year has certainly been the year in which 3D printing has inched its way into the mainstream. Another trend which has emerged this year seems to be one which recognizes the potential that 3D printing and recycling can achieve together. Every year hundreds of millions of tons of plastics are thrown away, damaging our precious environment, while we continue to manufacture even more plastics for the use within 3D printers. If instead of throwing plastic bottles away, we could recycle them into 3D printer filament, the world would be a cleaner, healthier place for us all.
