3D Printed Lock Barrels Brisbane

Changing lock barrels to suit any key 3D printed style

Are you one of those people who has been lying awake in bed just pondering the question “Can a lock barrell be 3D printed ?”  Well your question has now been well and truly answered.  Our 24 hour locksmiths have successfully 3D printed a range of lock barrels in different broachings.  Broaching to suit even high security registered key systems!

   3D printed lock barrel Brisbane locksmith       While these lock barrels are made of plastic, it is possible and cost effective to have the barrels 3D printed on a higher end metal 3D printer.  A metal printer can make the lock barrels as well as the entire locks out of materials such as Brass or Stainless Steel.  With additive manufacturing hardened anti-drill obstructions can even be added to the lock barrel.  This would give the lock a higher degree of security then many standard lock barrels.

Why would a locksmith want to 3D print lock barrels? Lock barrels are easily replaced in most locks.  A new lock barrel can be added to a lock to match the broaching of a different key.  Replacing all the lock barrels for a series of locks can make the locks all work on a new uniquely warded high security key.   The ability to reproduce a lock barrel to match a key system can unlock lucrative opportunities with already installed security key systems.

IMG_5008The bigger picture is that smaller companies can manufacture a lot more unique products that either did not exist or were not available or practical to manufacture using other techniques.

As additive manufacturing matures the security a locksmith can offer their customer becomes much more unique.  Custom broaching for locks is just the start.  Completely new lock and key designs can be prototyped quickly and manufactured on demand.  Where once locksmiths were tied to security key systems manufactured by large multi-national companies it is now becoming possible for small companies to manufacture on demand security products to suit a specific customer.

While Our plastic lock barrels might just be prototypes,  Production 3D printed parts are not far away.

3D printed safe lock

To make a 3d printed safe, you need a secure safe lock that can not easily be picked. This 3D printed safe lock is fairly easy to make and is classes as a high security lock. It can not be picked or bumped open as with regular house locks. So don’t lose the key! Or at least don’t lose the 3d printed file.

The safe requires the following parts

1 x lock body

1 x lid

1 x lock bolt

7 x levers

7 x discs

1 or more keys

I recommend making the parts from PET or PETG.  The parts for the 3D printed safe lock can be downloaded here. Printing can be done on your own 3D printer or sent to a 3D printing service that will make it for you.

Once printed make sure the bolt slides in and out of the lock body easily and is not binding.

Next check that the key will throw the bolt back and forth without binding. The key should be firm against the bolt as it is thrown but it should not bind. The key needs to fully throw the bolt out for proper operation.

The levers and discs should be the same thickness as they need to line up together inside the lock. If they are not all the same thickness, check the level of your 3d printers bed. The discs and levers when assembled in the lock should be level or just under the top of the lock. When the lid is fitted, the levers and discs should not bind. Adjust the levers and discs

Once assembled, make sure the lock is operating smoothly. If there is any problem with the safe lock operation, rectify the problems before using the lock on a locked safe as you will not want the lock to fail when locked on to a safe.

3D Printed Safe

Worlds first high security, key changeable 3D printed safe.

safe lock and key 3d printed

3d printed safe lock and key

It is made in all plastic, no metal at all. Why all plastic I hear you ask? Well it is made for sensitive areas such as mining, explosives and areas sensitive to electromagnetic radiation. As it uses no metal parts, it will not create a spark or ignition source around flammable materials. It has many different uses around sensitive electronic equipment and areas of high radiation.

As the safe is not magnetic in any way, detection from metal detectors and other standard detection devices will not work on this safe. This can be of use when the QLD police come to steal your business records without a warrant 🙂 Hidden in a wall or even buried, it would be very hard to detect a fully plastic safe.

Being plastic, this safe is obviously not designed as a high security safe for keeping millions of dollars. The safe is designed to show evidence of any break in attempt. If the safe has been compromised or attacked, there will be evidence of the attack. As the lock is not pickable, the only way to break into the safe is by destructive means.

The safe body is constructed in one piece. The one piece construction makes for a totally sealed safe with no seams to leak or be exploited. The plastic used is highly corrosive resistant to acids and almost all chemicals.

The safe uses a 7 lever and 7 disc

3d Printed Safe

high security safe lock. The safe lock is also 3D printed. To 3D print the lock, many modifications were done to ensure a strong usable design. The key is made thicker to make it stronger then a thinner metal key. The design of the lock is based on a Ratner key changeable vault lock. This type of lock was used over 100 years ago in high security safes and vaults. A Ratner safe lock of this design was even used to protect the Queens’ crown Jewels.

The lock is a key changeable design. In fact the combination of the lock is reset every time the safe is unlocked. In the unlocked position a new key can be inserted to set the combination of the lock. As a new key can be set so easily, it makes this lock design perfect for many applications where only one person at a time can have access to the safe. If a person locks the safe, no one else with a different key can unlock the safe. Another person with a different key can lock the safe when the door is open. The safe can also be made to operate with just one key combination and duplicates of that key can be made. Another key can be used to lock out the main safe keys from use. There are many different ways the key and lock system can be used.

The yellow on the lid of the safe was an attempt to add colour to the 24 hour locksmiths logo embossed on the front of the lid. Because of the plastics’ transparent nature and the light yellow colour, this did not turn out as planned. Future safes will not use this colour process.

The safe body can easily be changed to any shape of size required. Because it is 3D printed, it can be made to fit into oddly shaped recesses, furniture, or any other object you can think of.

Ratner Safe Lock

Ratner Safe Lock

Ratner Safe Lock Model

Safe’s are quite boring thing to look at and have in your home or office.  In Brisbane locksmiths install safes that are not so beautiful, well they are not beautiful on the outside.

Ratner Safe lock Brisbane locksmith unlockedIt is what is inside the safe that is most beautiful to locksmiths who work on safes.  Older safes have bolt-work and locks that were works of art.  Handcrafted locks were common place in older safes and to make the locks secure, manufacturers went to great engineering lengths.

The safe lock pictured here is a reproduction of a Ratner, key changeable safe lock.  Ratner began manufacturing safes in England in 1784.  They have many patents and lock designs to their name.   This key changeable Ratner safe lock was used on large commercial and bank vaults.   It was at the time considered to be unpickable, although, the unpickable status did not last.

This safe lock is unique in that every time the safe was unlocked, the key combination was reset.  By simply locking the safe with a new key, the combination is changed.

lock parts for 3d printing locksmith BrisbaneAs these locks are never seen by the public or owners of the safe, it is a shame for only locksmiths to see and touch these engineering masterpieces.   This lock has been designed as a printable fully functional lock.   If made in plastic, i would hesitate to install it on a safe though.  You can download this Ratener safe lock and make your own safe lock to see and enjoy.

Dont have a 3D printer? Even if you can not make it yourself, there are several printing services that will make this lock for you.

Some of the differences between this reproduction and the original Ratner safe lock are

  • Lock is able to be printed entirely from plastic or PET.
  • Lever Springs are designed to work with PET plastic, not brass as with original lock
  • Spacers between levers and rotating wheels have been eliminated.  Spacers are built into lever design and wheel design.
  • Curtain has been removed.  Just the bottom bolt throw is designed as per the curtain design.
  • Tolerances are quite low to allow for low printing tolerances.
  • No false gating.  You can add if you require.
  • Spoked levers and spoked wheels are replaces with a diagonal cog design.
  • Lock case made in single piece.  Original had 3 pieces to the body.

Making parts from recycled PET

Making parts from recycled PET

Custom Parts Manufacture

As locksmiths we always require custom parts to suit a wide variety of applications. Parts that are critical to security need to be made from aluminium, stainless steel or other metals to suit the particular requirement. Many parts however can be made from plastic. Parts such as lock packers, card reader housings, etc.

PET recycled from plastic drink bottlesAs much as possible we use PET recycled plastics to make parts we require. PET is recycled from common drink bottles that could otherwise end up in landfill. Using recycled PET is in line with our Brisbane locksmiths environmental guidelines to use recycled products where practical.

Printing with recycled PET is more challenging then other plastics such as PLA. PET is very fussy about temperature, extrusion speed, print speed and moisture.

Here are some tips for printing with recycled PET.

Make sure your filament is dry. In Brisbane, the air is very humid and the PET will suck up the moisture very fast. Keep the filament vacuum sealed when not in use. If it gets moisture in the filament, dry it thoroughly before use in a suitable oven.

Print on heated glass. Heat the glass until you get a firm hold from the PET. If the part lifts at the corners, add more heat to the glass to make it stick.

Printed parts are easy to remove from glass. Simply let it cool to room temperature and the part will release by itself.

3d printed PETG too fast

PET Printed too fast

Get the extrusion temperature right. PET generally needs to be extruded within a 15 degree temperature variance. This temperature will vary between different types of PET. Generally printing at around 245 degrees will give the best results and layer bonding.

Don’t print too fast. Trying to print PET too fast will give very bad results. Blobs, strings and very bad bonding is all that you will get with fast printing. The speed is easy to adjust with PET. Just run a test to set the speed. There is a sharp increase in quality when the print speed is just right.

Pet gives a strong well finished part. I would encourage people to use recycled plastics or biodegradable plastics when ever practical.
