A cheap, quick and simple solution for a 3D printer enclosure.
Also referred to as a photo/light, studio/tents, they are primarily used for product photography. The purpose of the tent is to diffuse the light through the nylon material removing shadows and reflections.
This tent environment can also serve as an breathable enclosure for your 3D printer!
Photo tents are readily available in a range of sizes and can be found for under £20. Many have a “pop-up” design making them very simple and quick to use, as can be seen above this one also came with a detachable door with a camera slit (see an alternative use for this below).
Benefits of using a tent enclosure
Quick and simple setup, easy to store when not required
Help stabilize temperature and minimize drafts, a factor to consider if using high temperature filaments such as ABS or ASA
This can remove the need for print skirts/wraps
Reduces smell and ultra fine particles (UFP), further improved when combined with a filter or extraction system. See here
Prevent debris entering the print area, see above!
Improve safety by enclosing hot and moving parts from children and pets
Keeps out dust
Using a photo tent enclosure
Before you start check the dimensions of your printer against the tent to be used. As you can see above the Prusa i3 MK2.5s fits perfectly in a 60x60x60 tent.
Place the printer in the tent and ensure there is sufficient distance between any moving, hot parts and the tent material. Connect power and USB if required, load a filament and power on. Moving all axis’s to their limit confirms clearance.
Camera door extractor setup
This tent featured a detachable front with a camera slit. I used the camera slit on the front door to insert an extractor duct. This helps to create a negative air pressure, drawing air through the breathable tent material and extracting to outside. A suitable HEPA/Carbon filter could also be used here.
Now its ready to print!
The display and control knob are easily accessible by lifting the bottom part of the detachable door, to start or make an adjustment during printing.
To trial the tent i set up a benchy print in ABS and monitored the temperatures with an in/out thermometer. The outside probe was inserted in a handy elastic loop at the top.
During the approximately 1 hour print the inside maintained a steady 29 degrees celcious with a room temperature of 20 degrees celcious.
Minimal odour was noticed whilst being in the room during printing and the Benchy came out with good layer adhesion and no warping.
The photo tent worked out as a great cheap and quick way to enclose a 3D Printer and improve the chances of a successful print.
The bonus of easily inserting an extractor duct through the camera slit was nice, and its original purpose is great for sharing photos of your prints!
My overall Verdict of the Phot-r photo tent is that it offers great value for money for the two uses it for fills. This basic tent may not be suitable if you are a professional photographer the creases in the nylon material and folded backdrops are noticeable and still present after several day of being setup. However it did a good job of improving the photos i took.
A photo tent is a great option if you are on a budget and do not have time to build a custom enclosure however there are a few considerations to take account off.
As the tent is not being used for its intended purpose its should NOT BE LEFT UNATTENDED with an operating or heating/cooling 3D printer inside. The tent material could pose a FIRE RISK.
Further more the breathable nature of the tent will limit the internal temperatures that can be reach, and is more affected by ambient temperatures.
However this means the psu and control board should be happy being left inside. If extended high temperatures are reached these components should be relocated to outside.
As might be expected there was little if any reduction in noise.
Where to get it
The Phot-R tent featured above is the 60x60x60 collapsible version available from amazon *HERE for £16.95.
Similar enclosure options
Growing on the photo tent enclosure, another alternative use of an already existing product is a grow tent. Used for growing exotic fruits, herbs, vegetables or seasonal fruits out of season, this option may offer improved thermal and sound insulation over a photo tent and has dedicated vents.
The above 60x60x60 grow tent is avaliable *HERE on amazon for £29.95.
Printer designated enclosure
There seems to be little availability of universal 3D printer fabric enclosures. However if you have a LulzBot TAZ or Mini you are in luck!
The Lulzbot nylon enclosure is listed on digikey.co.uk for £64.74 HERE.
In this article we will take brief look at how a ATX PSU can be utilized for various projects.
In this article we will take a brief look at how a ATX PSU can be utilized for powering various projects.
WARNING: Before attempting to work on any electrical components it is essential that you are competent, isolate all live conductors and prove this with a reliable instrument. This is imperative when mains voltage is involved, the PSU must be disconnected (UNPLUGGED). Also note there may be undischarged capacitors that also pose a shock risk, allow these to discharged before handling. Carry out the following at your own risk!
ATX (Advanced Technology eXtended) power supply units are used in computers. As a result they are readily available and cheap.
The primary purpose of a PSU is to turn the incoming 230v AC (alternating current) into DC (Direct Current), in the case of a ATX PSU, various outputs for the computers components.
They come with different specifications which are stated on the units label, an example of this can be seen below.
Confirm that the PSU is suitable for the desired use. For example a reprap style FFF printer: controls, motors and a single hotend using approximately 5 Amps and a heatedbed at 8 Amps. A total of 13Amps at 12 Volts gives us an estimated max 156W.
We need to make a few changes to replicate a motherboard connection to tell the PSU to turn on and deliver power. This is achieved by locating the PS _ON Green wire and connecting to ground, in this case i used 1oo ohm resistor connected to any of the ground wires (black).
At this stage the PSU should turn on and output power. Now is a good time to verify the outputs with a volt meter. Yellow (+12Va) and Red (+5V) to ground +/-5%.
We need to apply a dummy load to the +5V rail. A resistor or load such as a light can be used here. See the example below using a 12V 50w halogen light, at 5V the additional load is 10 Amps. Be aware that the light or resistor used will get hot!
At this stage the PSU should be providing a stable usable 12V supply.
The +3.3V does not have a use for this application however joining one of the +3.3V wires(Orange) to +3.3VS (Brown Sense wire) should remove any issues the psu has with detecting voltage drop of the 3.3V rail.
Last but not least is to check the current carrying capacity of the cables you have selected and ensure that this is greater than the maximum current drawn.
We can tidy up all the wiring and connect to suitable terminal blocks. Braiding of the cables can help reduce tangles and keep things neat.
As this is supplying a ramps 1.4 board with a heated bed i decided to use the +12Va (Yellow) for the 11A connection and +12Vb for the 5A connection.
One last suggestion is to verify the voltage and polarity before making the final connection to sensitive circuits to avoid damage.
If you feel i have left something out and would like to add to the above please leave a comment below.
From how 3D printing works to the best 3D printers, where to find the latest FREE 3D models and even money making business ideas. Here is were you will find 17 thing you need to know about 3D printing in the UK today!
What is 3D printing?
A process to make a
3D object by forming material in an additive way.
This is achieved by taking a digital 3D design or 3D scan of an object and translating them into layers which the printer then builds up to create the final item
traditional manufacturing techniques such as CNC milling which remove
material to create an object, 3D printing works by adding materials
also known as Additive Manufacturing (AM).
This process is carried out by joining or solidifying a material to build up layers to form an object.
Firstly, a digital file such as an STL which contains the 3D model is processed into layers by slicing at a determined resolution or layer height. Other settings such as speed and infill percentage are also set at this stage to create a print profile.
This print profile is then exported to the printer as a code and interpreted as x,y and z axis movements.
There are seven other main categories of 3D printing type, the first two are the most affordable and popular types.
Also know as Fused
Filament Fabrication or Fused Deposition Modeling the later being
trademarked by Stratasys in the United States.
This type employs an
extruder which feeds a continuous filament through the print head
nozzle or hotend.
The print head extrudes the x and y layers before moving the z axis to preform the next layer. Depending on the design, orientation and filament used temporary support structures may be required.
Below you can see 1 – nozzle ejecting molten material, 2 – deposited material, 3 – controlled x, y and z axis.
Within this category
are two different technologies, Stereolithography (SLA) and Digital
Light Processing (DLP).
SLA and DLP printing
employ a controlled light source to cure (photoplymerization) a
liquid resin into shape.
SLA is laser based, using a single beam aimed at the resin to be solidified on the build plate. Similar to FFF, the laser beam is rapidly aimed to solidify the x and y lines before the build plate is re positioned for the next layer.
Similarly DLP implements the pixels of a digital projection screen to flash an image onto the build plate, solidifying the exposed resin for the entire layer. This gives DLP a faster print time, but due to the nature of using square pixels the final print can exhibit visible vertical lines on the finished surface called voxels.
In addition, other categories of 3D printing include Powder Bed, laminated, powder fed and wire.
3D printers generally fall into three sectors; consumer, prosumer and commercial/industrial grade.
Key considerations when looking to purchase a 3D printer should be:
Do you need a 3D printer?
3D printing is a great technology, but does have a steep learning curve and will require a significant investment of your time as well as your money. If you only require occasional use of a printer it might be worth considering using a 3D printing service.
Above all, entry level FFF printers are the most accessible with a wide choice of manufactures available in the UK and prices starting from under £200. Professional FFF printers range from about £700 up to £6000+ for commercial.
However in recent years SLA and DLP resin printers have become more affordable starting around £300.
See more about printer prices for the home and other costs below.
Kit vs ready assembled
You might be considering a kit sometimes called part assembled, but its worth checking the level of support provided by the manufacture, warranties and quality of the components. In addition these kits are sometimes supplied with exposed power supplies which pose a potential hazard if handled incorrectly.
Furthermore, if you purchase a ready assembled printer from a UK retailer you will have more consumer protection to fall back on if things go wrong.
Is measured by the x, y and z axis to give its build volume. The greater the build volume the bigger you can print, and the more you can print at one time.
Auto bed LEVELING
Ensuring a level print bed is important to maintain an equal distance between the print nozzle and the bed surface. Above all this is can be the source of many printing issues if not setup correctly.
Additionally, printers with auto bed leveling use a sensor to calibrate the distance and makes software adjustments to the z axis to compensate for any inaccuracies.
This can save a lot
of time and faffing about especially if you are new to 3D printing.
All prices found at the time of writing, with the ability to ship to the UK.
Where to buy
Certainty, for the greatest level of support purchasing from a reputable local shop would be recommended. Some manufactures sell directly such as Prusa. However other manufactures sell through preferred re-sellers, this information can usually be found on their website.
Amazon.co.uk can be
a great source for finding the latest models at very competitive
Be particularly cautious of buying kits from suppliers outside of the UK as these do not necessarily have to meet the same standards of assembled products sold in the UK.
Read reviews, check
out the seller and take your time.
3D printer prices for the home
As you can see above 3D printers vary greatly in price. For example, a assembled entry-level FFF 3D printer for the home can be had for as little as £118.66 Plus UK delivery.
According to https://pricespy.co.uk XYZprinting da Vinci Nano was retailing for £165.60 at the beginning of 2019. That is a fall of more than 25% over a six month period.
The same printer can be found on Amazon.co.uk for even less, although was temporarily out of stock at the time of writing.
Because the development of this technology is rapidly improving, prices of older models are dropping. This is also increasing the amount of 3D printers available on the second hand market in the UK.
During May 2019 on a local classifieds website I found an Original Prusa i3 MK2.5S for £225 including 4 rolls of filament!
With prices dropping
below £200.00, now is a great time to start thinking about
purchasing your first 3D printer for the home.
Beside the initial
outlay for a 3D printer there will be additional expenses along the
These include, running Costs, energy use, material cost, maintenance, tools, personal protective equipment and consumables such as paper towels and propranol alcohol.
Once a 3D model has been created or downloaded, firstly it will need to be prepared to export to your printer. This is achieved by importing your CAD model file e.g STL into the slicing software. Secondly, the file is then sliced into layers, and other settings such as speed, infill, supports and temperature are calculated.
Finally, the model is now ready to be exported as a G-code to the printer.
Additionally, there are also tools for rendering meshes and repairing files.
Additive manufacturing is increasingly finding its place in schools, businesses and the home. Potential hazards to health and safety can arise from the 3D printing process. We will look at some hazards relating to desktop FFF printers and measures that can be taken to help reduce the risks of injury and adverse health effects
High temperatures such as the hotend and heated bed
Allow sufficient time for the printer to cool before removing prints and maintenance. Signs and barriers, Enclosures, Hotend sock, Gloves
Removing support material
Wear safety eye protection
Handling support material and prints
Wear gloves, remove sharp parts by filing and deburring
Exposed terminals and wiring
Contain exposed conductive parts within a suitable enclosure. Check for wear and damage to cables before powering on
Heating and extruding filament
Breathing vapor and particle emissions
Use in a well ventilated area, extraction and filter systems, enclosures
Pinching or trapping hand/fingers
Not coming into contact when the printer is operating. Signs,barriers and enclosures
Exposed high temperature surfaces
Not leaving the printer unattended. Fire detection – Smoke alarm. Contained within a fireproof enclosure. Local fire suppression, such as a fire extinguisher
Similarly, considerations such as printing items to be used with food should be ‘food safe’, and reliability of safety critical parts need be taken into account. For commercial applications carrying out a risk assessment would be highly recommended.
should be considered for resin based printers.

Essential 3D printer tools, equipment and consumables
Take the stress out with these must have items to include in your 3d printing tool kit:
Additive manufacturing is reshaping opportunities for new and existing businesses. Many big businesses such as Boeing and car manufactures like BMW and Ford have already embraced this emerging technology not just for rapid prototyping but as a feasible manufacturing process.
There is no one answer to how 3D printing can be a business in it own right, but as a technology with potentially endless possibilities we will look at several ways you can get started:
Designing niche parts or products for other people or businesses
Selling your own designs and models
Selling 3D prints
Offering a local 3D printing service
Selling 3D printers and related supplies
Fixing and maintaining printers
Tuition and support services
Investing in 3D printing related stocks and shares

For more on the future relationship between 3D printing and intellectual property, check out the following:
The UK’s intellectual property office (IPO) have published an in depth 88 page research report on 3D printing and IP futures across six countries available here.
A decentralized method to authenticate the data usage such as blockchain technology could be a new way forward. Blockchain tech is being explored by the likes of GE and IBM to protect IP and verify the manufacturing process from the design file to materials and printer configuration.
3D Printing and the environment
Looking at the impact on the environment both directly and indirect, below are some good and not so good affects:
Reducing Waste Materials
manufacturing methods have reduced waste material in comparison to a
subtractive manufacturing method such as CNC machining.
Using 3D printers to
make replacement parts to carry out repairs, increasing an items
Improving efficiency and lowering energy use
by the development of lighter 3D printed parts for use in planes and
3D printing new
tooling and parts to increase performance and efficiency of existing
mentioned, reduced waste material also helps lower the energy used to
produce the raw material in the first place, this could also be said
for extending the usable life of existing items.
The ability to 3D
print complex parts as one piece reducing assembly requirements and
for the geographic area, minimizing transport of the final item.
Printing products at
home reducing the need to travel to shops or get deliveries, although
the raw materials would still require to be transported. This could
be further improved if the printing material was sourced and made as
local as possible, or even better from locally recycled plastics.
3D printings ability
to make different products in low quantity on demand locally would
help reduce the need for storage and the related energy required for
those storage facilities. The warehouse is now in the clouds!
When 3D printed products reach the end of life they could be recycled into a reusable print material or filament ready to re printed into something new.
For example old
shoes could be recycled with minimal need of additional material to
make a larger size, or just remake them.
Waste and by product
could also be utilised in this way.
Removing plastic waste from the environment especially the sea and coastal areas which the UK has plenty of, and then converting them into filaments.
Increasing the productivity of C02 Carbon capture is a new
Furthermore researchers at the UCLA have been exploring the idea of
incorporating captured carbon into 3D printed building materials.
Helping regenerate natural environments, for example artificial ceramic reefs to foster new coral growth.
Not so good
The high temperatures and resins used in 3D printing release volatile organic compounds, some of these VOCs are dangerous to human health and cause harm to the environment.
3D printing consumes
a considerable amount of electricity, arguably more than traditional
methods like milling to make the same part.
such as selective
laser sintering (SLS) leave
a substantial amount of raw material behind which
have to be refreshed at
rates between 35% and 50%.
What can you do?
Reduce material use by using lower infill rates
Print multiple items at once
Change orientation to reduce support material
Use eco-friendly materials such as PLA, a corn based renewable type of thermoplastic. There is even a hemp filament that can be sourced here. It can also print at lower temperature than PLA.
Use an enclosure and appropriate filters
Insulate heated print beds
Recycle failed prints and support material.
Try to use renewable sources of energy
Obtain materials and supplies from local sources
Use your printer to make things to reduce your waste, energy usage and improve our environment.
A brief History of 3D printing
3D printing technology has the potential to connect us with our heritage and usher in a new era returning to local distributed manufacturing based on digital fabrication.
