3D Printing: Friction (Spin) Welding Video Tutorial

February 8, 2018 | ProgressTH 

If you don't like waiting for glue to dry and want instant, solid joints for your 3D printed projects, friction (spin) welding might be for you.

All you need is a rotary tool and a small enough collet for a short length of 1.75mm filament, turn it on and move it along the joint.
SAFETY: Also make sure to wear eye protection. The filament is spinning at high speeds and will very often snap off and go flying. Little pieces of plastic are also ejected by the process depending on your technique, angle, and the quality of your filament.
The spinning filament creates heat via friction and fuses itself along with both pieces of plastic along the joint.

We use PLA, but have had success in the past using ABS as well. Practice makes perfect so be patient and make use of those failed prints!

We have done a written tutorial on how to fill large gaps here.

Bangkok Maker Faire 2018

January 26, 2018 | ProgressTH Last weekend was Bangkok Maker Faire 2018. Local makers, students, teachers, and local businesses gathered to show off their latest projects and products. Everything from 3D printing and electronics to robots and virtual reality (VR) were on display.

ProgressTH was represented as well, showcasing our latest projects including our newest opensource 3D printed DIYbio lab equipment, our portable tabletop hydroponics system, the latest results of our collaboration with Queen Sirikit National Children's Health Institute (QSNICH), our 3D printed rigid heddle loom, and a 3D printed Arduino-enabled USB volume control knob. All projects can be found on our Thingiverse account here.

Several things stood out this year. One was the high level of awareness and knowledge among young students pass through of 3D printing, hydroponics, and 3D design.

Another was the amount of 3D printing used in projects not necessarily featuring 3D printing itself. For instance, we saw a rescue robot with many of its parts 3D printed. Pleum of Meplus Hobby showed us some camera equipment he used 3D printing on, some of which you wouldn't have even guessed was 3D printed unless he told you. 3D printing is being used so ubiquitously now by local businesses, designers, and makers that its use is almost a footnote if mentioned at all.

Urban Agriculture: Getting Started With Indoor Hydroponics

January 25, 2018 | ProgressTH.org Hydroponics is a method of growing plants without soil. It allows food to be grown virtually anywhere. It is a technical method that is easy to learn and get into, but takes a bit of time and patience to master. Luckily, it is not as intimidating as it may seem, and as more people begin experimenting with hydroponics, the wealth of information they are sharing online makes it easier than ever to get started.

Why Hydroponics? 

The dense urban sprawl of Bangkok makes it very difficult to grow your own food with traditional means. Safe soil in an open space with adequate sunlight is hard to find. Even on Bangkok's many rooftops where open space exists, bringing soil upstairs and maintaining a garden under the beating sun and amid flocks of marauding birds is a lot harder (we've found out) than it seems.

Hence hydroponics. With hydroponics, you can grow food anywhere. Outdoors, indoors, with or without access to sunlight and without any need for soil. After experimenting with rooftop and balcony gardens with mixed results, hydroponics enabled us to finally grow enough food, indoors for daily consumption.

For now we are growing only salad greens. But hydroponics can be used to grow a wide variety of fruits and vegetables. It is just a matter of adjusting your grow space, containers, nutrients, and lighting, all of which we will explain below.
