ColorFabb LW-PLA Expanding Foaming Plastic Filament for 3D Printing - Part 1 Testing and experimentation

RichRap

ColorFabb LW-PLA (Expanding/Foaming PLA) Filament for FDM 3D Printing - Part 1 Hello everyone, Richard here - In this blog post I'll be looking at a new and unique 3D Printing material for the FDM/FFF process. You can print in both it's natural state, just like solid PLA, and with increased temperature a foamed state, so the same part can contain solid and foamed layers or features, it's like having a multi-material in a single filament.

PETG Filament: Properties, How to Use, and Best Brands

3D Printing Hub

Although PLA and ABS remain the most widely-used filaments in 3D printing today, alternative materials have been starting to gain some popularity. PETG has been widely used for outdoor signs due to its excellent printability and laminating characteristics. PETG filaments have been described as having a combination of the best properties of PLA and ABS : they are stronger and more temperature resistant, while still being easy to work with. How do you work with PETG filaments?

3D Printing with Nylon 618 filament in Tie-Dye colours

Nylon has amazing self-bonding properties making any FFF (layer-by-layer) printed objects very strong and less prone to de-lamination. From the moment I spotted the 618 Nylon was available I wanted to try colouring the raw filament with more than one colour, something I have always wanted manufacturers to make is a range of filaments that have changes of colour during the roll or even across the roll, now I had a way to do it myself.

This 3D Printing filament if one of the most fun to use that's in existence today. It actually does not shine up like other metal filaments (you can get a little shine if you almost kill yourself polishing it). Be gentle with the filament, it's not very brittle, but more fragile in filament form than normal PLA. Not greatly, but they do get weaker and are more likely to de-laminate if dropped, knocked etc.

It is often used as a laminated layer over Polycarbonate (PC). Acrylic is also available in a filament form which can be used with 3D printers to create prototypes using computer-aided design files.

Various colors of acrylic filaments can be used to 3D print a large variety of models.

ABSolution

HydraRaptor

For example, if I fold a short piece of filament double and let it go this is what happens :- PCL is rubbery and springs back almost straight, HDPE is a lot less springy. After that I make test blocks to fine tune the temperatures and find the best speed and filament diameter to build with. Part of this is due to the fact that it has to run faster (for the same flow rate) as the ABS filament I have is only 2.75mm rather than 3mm.

Wednesday, May 25, 2011. Selectively making parts of object stronger.

Sky Hook

HydraRaptor

I have found that the most convenient way to provide the filament feed is to throw the whole reel into a large hanging basket and suspend it over the machine with a ball bearing. The machine pulls the filament from the centre of the coil through a hole in the bottom of the basket. As it does this the basket rotates to prevent the filament being twisted. The top filament can be used simply by passing it through the centre of the lower basket.

Pot black

HydraRaptor

The temperatures seem to be the same as those for green, i.e. higher than I have used for plain, but it is harder to get it to stick to the raft and it de-laminates more readily. With plain ABS I can have it at the normal layer height above the raft (filament diameter * 0.8) Another problem is that the extruded filament is not smooth. It is particularly noticeable when laying the thick filament for the first layer of the raft.

Thoughts on rafts

HydraRaptor

It is a solid dense foam 3mm thick, not the type that is soft foam laminated with paper. I glue it to a piece of wooden floor laminate with Evostick contact glue. The filament diameter I use for the base layer is twice the nozzle diameter or 0.8mm, whichever is the biggest. The head is relatively low, so that it gives a wide filament pressed against the bed. The filament diameter is 1.5 Erik asked me for details of how I do the rafts so here are my thoughts.

AFRL – Embracing Opportunity: Additive Technology for Manufacturing

Additive Manufacturing

The technology further evolved to include fused filament modeling, wherein fibers of plastic thread were melted and joined together to form a new object. Conventional circuit fabrication requires the lamination of a series of conductive and insulating layers in a patterned fashion, resulting in a rigid circuit board.

Stepping up production

HydraRaptor

The outer wall is always two filaments thick, one is the perimeter and the other is the ends of all the infill zigzags that meet each other. With 0.5mm filament and a layer height of 0.4mm the filament threads are 0.6mm wide so the side walls are 1.2mm thick. The board is not strong enough to resist the warping on its own so I stuck it to the back of some floor laminate with Evostick contact glue.

Mendel90 design improvements

HydraRaptor

The problem seems to manifest itself when extruding slowly because it takes longer for the filament to pass through the hex grub screw (which is the Achilles heel of the J-Head because it is wider than the rest of the filament path) and so has enough time to soften and buckle. Ironically it is also more of a problem when extruding at lower temperatures because the filament gets harder to push and so buckles at a lower temperature.

Hot Stuff

HydraRaptor

The filament changes from green and smooth to almost cyan and a rough texture: - Again under the microscope the surface looks very different :- My theory as to what is happening is that the green dye is composed of yellow and cyan dyes, and the yellow component is boiling off, disrupting the surface. The hot objects seem very strong and feel like they wont de-laminate in a hurry.

No compromise extruder

HydraRaptor

T0 keep the molten filament path as short as possible I combined the heater and the nozzle and made it from one piece of aluminium. That stops the filament sticking so that it can be wiped off reliably with a brush. I normally stick items to be milled onto the back of a floor laminate off-cut using stencil mount spray. Actually it seems to jam when it is leaking badly, which implies the pressure of the molten plastic is much higher as well as the force to push the filament.

Dribble and smoke

HydraRaptor

The first problem I decided to tackle was extruding just the right amount of filament. Using the equations I described last time, I know what feed rate is required to give a particular diameter filament and what its exit speed will be. The problem is that when the extruder stops, the filament continues to extrude slowly for a while afterwards. So, before I can start extruding I need to remove the excess filament hanging from the nozzle. Not a very good day today.

Golden wonder

HydraRaptor

The filament didn''t span the void very well as it is a very big void, I have no fan running and there is a lot of heat rising from the bed. That caused some filament to stick up and collide with the head. This time I also dropped the filament temperature to 220°C, so it spanned better and the head did not get spun. Having the object kept warm seems to allow a lower filament temperature without losing strength.

How to Smooth PETG Prints
