At the time of creating this page 3D printing is still in its infancy, but in the belief this technology will become more wide spread, on this page we include some spare parts and small items useful in the home production of biodiesel and WVO preparation.
There are currently two types of plastic commonly used for 3D printing, PLA and ABS. Of these two PLA is the easiest to use and appears, from tests so far to be reasonably resistant to biodiesel, methanol and WVO. It has a low melting point and hence can't be used for any high temperature applications and it is not compatible with any of the catalysts used in biodiesel production. Additionally, due to the way 3D prints are laid down, it is strongly recommended that printed parts are not used for any pressure applications without rigorous tests being carried out by the person manufacturing the parts.
It would appear that some of the more commonly used pumps in the UK have terminal boxes manufactured from a plastic that's not compatible with biodiesel. It's hoped that the items below printed in PLA should out last the original parts.
These designs are offered for personal use only and are used entirely at the printers risk. No liability will be accepted by Biopowered or the creators of these designs as to their suitability for purpose.

TAM 105 terminal box
This box also fits a a GRC Aquatec 82lpm pump. Longer screws may be required as the wall thickness has been increased from the original design.

TAM 120 terminal box
Fixing pillars within the box have been made considerably stronger by blending them into the box walls.
Longer screws may be required as the wall thickness has been increased from the original design.

Land Rover 300 tdi injection pump and flywheel locking tools
The flywheel tool requires a 3/16 or 4.7mm diameter drill or pin to engage with the hole in the flywheel (note this is only strong enough to locate TDC, not to undo any bolts etc). As with most prints, the hole may need to be cleared with the drill. The tool has a taper which is intended to bind on the ¼" threads and hold it in place.
The IP locking tool will require two M8 bolts circa. 30mm long to engage with the IP pulley, and a 9.5mm diameter bar to lock the pump flange to the IP body.
Print both with a good wall thickness and fill density.

TAM 120 replacement cooling fan
This broke up possibly due to the plastic splitting following being forced onto the motor shaft.
The replacement was designed to be stronger given the limitations of 3D printing. The shaft boss was increased in diameter and the blade thickness was increased by 1mm. Additionally the boss and all the blades were given a large root radius.
- TAM 120 replacement cooling fan
Broken fan.
Printed replacement fitted to motor.
As can be seen from the light coloured swarf, the fan's a slight interference fit on the shaft.
Mono ML and MM coupling covers
Often missing from second-hand pumps, this version is 2mm thick compared to the originals which are 1.5mm.
Printing on edge with support and no fill should produce good results. Two are required per pump.
- Mono ML and MM coupling covers
Comparison of original and printed covers.
Printed cover fitted to pump.
Mono MS coupling covers
Often missing from second-hand pumps, this version is 2mm thick compared to the originals which are 1.5mm.
Due to its shape quite a lot of plastic is used for support. Two are required per pump. Unfortunately this cover won't fit the MS predecessor, the M25, which looks similar and was never designed to have a cover.
- Mono ML and MM coupling covers
Comparison of original and printed covers.
Plastic wasted in support.
Printed cover fitted to a rather well used pump.
20 ltr plastic can adapter
A threaded adapter which should fit most 20 ltr plastic cans and allows a 25mm ID PVC pipe to be fixed as a spout. This arrangement is useful for filling vehicle tanks without the aid of a funnel. A vent hole needs to be drilled in the top of the can to admit air. 25mm PVC pipe is available from most aquatic suppliers
A file is included to print the sealing ring using a flexible filament such as Ninja-flex. Alternatively a seal can be cut from a suitable material circa 3-4mm thick with the dimensions ... OD 62mm ID 50mm.
Due to the profile of the threads, the item is best printed at 100% fill, hose tail up and with support. Careful cleaning of the support remnants will be required.
- 20 ltr plastic can adapter
Cap and hose fitted to a can ... note the vent hole in the top of the can plugged by a tapered piece of plastic.
The 25mm ID tube is quite a tight fit, but a hose clip can be used for additional security.
Lowara CEAM 70/5-V terminal box
As with many other pumps the terminal box on this Lowara pump doesn't seem to be made to last. The replacement was designed with considerably thicker walls and sturdy reinforcement. Additionally, the capacitor housing was enlarged to make fitting after market capacitors easier.
- Lowara CEAM 70/5-V terminal box
The somewhat fragile original terminal box.
Thicker walls, enlarged pillars and more room in the capacitor housing.
Assembled on the pump.
Closed up and sealed for use.
