There are many clever ways to make stronger 3D prints, be they by the use of special slicing algorithms or by unusual filaments. [Brtv-z] has taken a more straightforward tack, by making glass-reinforced prints using painters fiberglass mesh tape.
It’s a laborious technique that involves stopping the print to manually place the fiberglass at each successive millimeter of print. The resulting test piece comes off the print bed festooned with fiberglass mesh, and once it’s been trimmed, he subjects it to some tests which you’ll see in the video below the break(Russian language, but there are subtitles).
The tests are fairly rough and ready involving a hammer (we winced at the hammering in a vice, but of course this piece isn’t forged steel!) and standing on a flat piece of print balanced between two blocks. As you’d expect, the reinforced piece appears the stronger, but these tests would benefit from a calibrated set-up to quantify the strength.
So if you’re of a mind to experiment, this certainly seems like an accessible if rather tedious way to make glass reinforced 3D prints. If you then want to characterize them, remember this can be done with a bit of farmyard engineering if you have nothing better.

There are many of us who might have toyed with the idea of building a car, indeed perhaps more than a few readers might even have taken to the road in a machine of their own creation. Perhaps it was a design of your own, or maybe a kit car. We think that very few of you will have gone as far as [Vũ Văn Nam] and his friends in Vietnam. In their latest video they compress a year’s work into 47 minutes as they craft a beautifully built replica of a Bugatti supercar. If you haven’t got a few million dollars but you’ve got the time, this is the video for you.
The skill involved in making a scratch-built car is impressive enough, but where there guys take it to the next level is in their clay modeling to create the moulds for the fibreglass bodywork. Taking their local clay and a steel frame, they carefully hand-sculpt the car with the skill of an Italian master stylist, before clothing it in fibreglass and removing the clay. The resulting fibreglass shell can be used to make the finished bodywork, which they do with an exceptional attention to detail. It might be a steel-tube home-made spaceframe with a wheezy 4-cylinder Toyota engine behind the driver instead of a 1000 HP powerhouse, but it surely looks the part!
Looking at the construction we’re guessing it wouldn’t pass an Individual Vehicle Approval test for roadworthiness where this is being written, but at the same time it wouldn’t be impossible to incorporate the extra work as this is a proper road-going car. The video is below the break, and though the few pieces of dialogue in it are in Vietnamese you probably won’t need to turn on the auto-translate to follow it.
This isn’t their first fake supercar, there’s already a Ferrari in this particular stable. Meanwhile if you’re of a mind to make a car, consider the world’s most hackable vehicle.

Futurism is dead. At least, the wildly optimistic technology-based futurism of the middle years of the 20th century has been replaced in our version of their future by a much more pessimistic model of environmental challenges and economic woes. No longer will our flying cars take us from our space-age wonder-homes to the monorail which will whisk us through sparkling-clean cities to our robotised workplaces, instead while we may have a global computer network and voice controlled assistants we still live in much the same outdated style as we did decades ago. Our houses are made from wood and bricks by blokes with shovels rather than prefabricated by robots and delivered in minutes, and our furniture would be as familiar to a person from the 1950s as it is for us.
A Plastic Future That Never Quite Happened
There was a time when the future of housing looked remarkably different. Just as today we are busily experimenting with new materials and techniques in the type of stories we feature on Hackaday, in the 1950s there was a fascinating new material for engineers and architects to work with in the form of plastics. The Second World War had spawned a huge industry that needed to be repurposed for peacetime production, so almost everything was considered for the plastic treatment, including houses. It seemed a natural progression that our 21st century houses would be space-age pods rather than the pitched-roof houses inherited from the previous century, so what better way could there be to make them than using the new wonder material? A variety of plastic house designs emerged during that period which remain icons to this day, but here we are five or six decades later and we still don’t live in them. To find out why, it’s worth a look at some of them, partly as a fascinating glimpse of what might have been, but mostly to examine them with the benefit of hindsight.

Generally, any activity out on the water is more dangerous when done at night. Hazards are less visible, and it can be easy to get into trouble. [Xyla Foxlin]’s party canoe can’t help with that, but it does look the business after dark.
The canoe is made out of fiberglass, directly formed onto an existing canoe to make getting the shape right easy. It was formed in two halves, with special care taken to make the final result as clear as possible. Obviously, fiberglass is never going to be perfectly transparent, but [Xyla] does a great job of getting a nice translucent frosted look. The final effect means that it’s the perfect canoe to stuff full of addressable LEDs. A string of WS2812Bs, hooked up to an Arduino, make for an appealing lightshow when boating at night.
The diffusive nature of the fiberglass really makes the difference here. We’ve talked about the topic before – it’s the key to making your glowy project really pop. Video after the break.
