Amazing resource for the process behind making an extruder

Solar Sinter Project

Markus Kayser – Solar Sinter Project from Markus Kayser on Vimeo.

In a world increasingly concerned with questions of energy production and raw material shortages, this project explores the potential of desert manufacturing, where energy and material occur in abundance.
In this experiment sunlight and sand are used as raw energy and material to produce glass objects using a 3D printing process, that combines natural energy and material with high-tech production technology.

Solar-sintering aims to raise questions about the future of manufacturing and trigger dreams of the full utilisation of the production potential of the world’s most efficient energy resource – the sun. Whilst not providing definitive answers this experiment aims to provide a point of departure for fresh thinking.

This project was developed at the Royal College of Art during my MA studies in Design Products on Platform 13.

Alot of very handy knowledge to be found here. Its nice to see others are thinking the same thing, but also a bit daunting that engineers have not managed to do it yet.


The 3d printer I plan on making, its a simple entry level printer which is designed for easy assembly and operation.

Printrbot has been one of the most succesful campaigns on Kickstarter.

Reprinting Waste

I have been thinking about living “off the grid”, basically living in a self sufficient way. A way of living that does not necessarily rely on outside services or resources to sustain living. I have also been thinking alot about 3d printing, its a very hot topic at the moment. It sounds like 3d printing is going to change much of how we manufacture things from products, to food and body parts. There are massive implications in industry and also for the home user. The home user can now purchase or even make a 3d printer for around or less than $1000 depending on the model. This could have a huge impact on the types of things people could now manufacture at home and create a whole new level of self reliance and moving away from relying on industry else where. All that is needed is the CAD file (possibly internet or usb stick), electricity, 3d printer and the raw material.

I am planning of tackling the issue of having enough raw material to be self sufficient. One thing that strikes me is the fact the designs continually gets upgraded and old designs become redundant. It would be amazing if you could somehow feed these old designs back through a 3d printer to become something “new”. It would also solve one of the problems that I imagine 3d printing will create, namely when everyone is printing anything they want, what are we going to do all the stuff that is printed once people lose interest in it and it simply becomes more crap for landfill.

Also imagine if we could take the stuff that we would normally put into landfill and were able to convert that into a usable and printable material ready for 3d printing.

This would be great for a student, for someone living far away from retail stores, somebody who does not want to spend money but spend waste materials to get things, or simply for the environmentally concious. At a larger scale if industry could use waste this could have tremendous cost and environmental benefits.  I plan to build a 3d printer this semester, and although the abs that we hope to print with is not too expensive it would be extremely liberating to know that I don’t have to be overly careful with what I print because I know I can easily re-use it, almost up-cycling it, maybe side-cycling it.  It would also be a very cheap if I could take things that others deem as waste and turn that into a printable material. What are the implications for developing countries where manufacturing using 3d printing is too expensive, or materials are hard to get? Could this be a viable means for waste to be turned into 3d printables for developing countries?

So now I need to begin to research which materials could be used and what kind of a process.

I am thinking whatever material I end up using it will probably have to be extruded into some sort of filament. So a filament extruder, especially because a lot of the open source 3d printers have gone down that path, it seems it is a simpler technology than using powder or lasers.  I was at first trying to think of a way that ABS, PP, PLA or even PET could be reused ready to 3d printed. Imagine looking for PET bottles so you can print things from them, or taking all your PP coat hangers and turning them into a new type of container. From the plastics I have have now drifted into considering homemade bio-plastics, paper mulch, or even food waste. It would be amazing to be able to print in a variety of materials to create complex objects made of many composites. I think however to start, looking into one material will be best.

So how does an extruder actually work? I imagine it to be like a metallic syringe with an element and something to catch what comes out of the syringe and continue to roll it up into a manageable form. The beginning of the syringe may have a type of cylinder which is filled with a powdered form of the waste, which is then pressurised to force it down into another chamber of the syringe which is heated. The heated area allows for melting and therefore a recombining of the materials. The recombined materials then come out of the other end of the syringe, through a narrow opening and are pushed out at a continuous speed to ensure a continuous thickness. The extruded part then solidifies and becomes filament, being wound or collected in a way that the 3d printer can use it.

Is this all possible? I think so. Can I do it in less than 9 months? Maybe? I’m looking forward to finding out at this point.

3d printing will be a major part of manufacture and perhaps life in the future. The pirate bay already has a CAD files section. It would be amazing to have an impact on some of the environmental implications 3d printing may have by re-using old prints and at the same time helping people to become more self sufficient.


The beggining of the end

This is now my final year of the Industrial Design program at RMIT. During this year I will be completing a major project over the course of two 15 week semesters.

At this point in time I am not completely  sure what it is I will actually be doing. Last year I anticipated to do work revolving around brands and turning their influence on consumer behavior into a positive thing. I was hoping to do this by creating an application which would work on smartphones which could be used during a shopping experience. The application was to profile different brands and their respective products almost as though it were a psychological assessment of the brand/product. Giving various bits of information –  such as for whom this brand was developed, how it targets a consumer, where the brand or product comes from, how it was constructed and by whom, the known longevity of the product, what kind of an environmental impact the brand/product has, etc. Essentially it was to dissect the brand and product into useful little bits of info for the consumer, making them more aware and knowledgeable as to how they are being influenced in there buying behaviors, and hopefully by raising awareness and giving this knowledge, allowing the consumer to make a better environmental and economical choice.

I have decided to drop this idea.There are various reasons, relating to scope, effectiveness and interest.

I still find the idea of a brand fascinating and feel that everything everywhere belongs to some sort of brand, be it a  branded product, branded tribe, to a subconscious branded social construct – branding is part of human nature.


For this year I want to focus my energies on something more tangible and do-able, something where I can think but at the same time get my hands dirty and make something.
