Flatforce is a new kind of buildplate. is not a adhesive sheet, but it’s relatively stiff. The thickness of Flatforce buildplates is 2,5 mm circa. Is not a flexible base, so don’t bend it!
Flatforce is a great substitute of your glass/alluminium buildplate. It is able to withstand up to 95°C (203°F). The LENE PLATE is able to withstand up to 105°C (221°F).
Flatforce and LENE Plate life cycle is much greater than thin adhesive sheets, but it is always to be considered a consumable product. The standard life cyclemost depends of the customer usage. Always use the same material (or similar) could increase significantly the life of the product. Constantly changing different materials can shorten the life of the product. To get the greatest Flatforce’s performance we not recommend using it with many different materials. If there is this need, we recommend the user to purchase a specific Flatforce buildplate for each materials.
Installing Flatforce buildplate is very easy. Flatforce is a rigid buildplate, not flexible, and it can be your glass/aluminium-bed substitute.
For clamping Flatforce on your printer you can follow two paths:
The simplest way is that into using the classic binder clips. We recommend to place the binder clips in a uniform manner on the Flatforce’s edges in such a way as not to have the imbalance forces. The simplest way is that into using the classic stage clips cards. We recommend to place the springs in a uniform manner on the edge of Flatforce in such a way as not to have the imbalance forces. Apply homogeneously the clips on the perimeter means that you do not incur any banding problems. The binder clips is suitable for printing tables up to a 250×250 mm area.
For best results make sure that the fixing area of application is flat. For example, avoid attacking flatforce directly on a smaller pcb resistance or the like with respect to the printing bed. In this case the binder clips will push on one side of flatforce without an adequate underlying support, so Flatofrce flexing in the central area and making it unusable.
Flatforce Fix Kit
Another even simpler method is to apply the heat-resistant double-sided tape on the underside of Flatforce. Fix kit is a set of pre-cut double-sided adhesive strips which can be arranged in a uniform manner on the lower part of flatforce. On request it can be supplied (at extra cost) a fully bi-adhesive surface behind. Thanks to Fix the kit, large Flatforce buildplates surfaces are perfectly flat to the print base.
Flatforce is know considered a printing medium so it can not also be support structure at the same time. For example you can not apply the elements directly on the flatforce bottom, without any support in metal base below. You can not drill flatforce to apply the leveling bed screws.
Flatforce is installed correctly on your printer, before you proceed with the first print is always a good idea to control the Z-axis height with the new flatforce (remind the thickness of Flatforce).
Then proceed with a manual or automatic leveling. Flatforce not contain metal so if you use an inductive Z-probe, calculate the thickness of Flatforce before starting this procedure. The nozzle height toFlatforce must be very close, better to start with a distance of +0.05 mm or less. Given the roughness of Flatforce, for the most difficult materials we recommend that the first layer is very close on the surface of Flatforce. This means that all of the Flatforcesmicrophores will be full clogging with the first layer. If for any reason you were to stop the printing, we recommend to continue printing until at least the second or third layer, thus facilitating the removal of the press and thus limiting the residues on the printing table.
**Make this operation with a clean and cold nozzle. Hot nozzle can ruin the Flatforce surface.
Printing with Flatforce
Happened the calibration can proceed with printing of our object. All our instructions are obviously closely related to the first printing layer. Flatforce can be used with direct printing of the object, use the function brim and even raft. This part of the guide are suggestions for the Flatforce users.
We recommend to use Brim or Raft option, with a little external base, the 3d print can be removed faster and more easily. As for concerns the setup for Brim, if you are using Simplify, we suggest to use 5 -6 laps and two layers high (because the first layer will be almost canceled with the micro-porosity, if we take the height of the first lower layer at 100%). During printing of technical materials such as ABS and nylon various a closed chamber or heaer chamber can greatly help the adhesion of the piece to Flatforce and also between the layers of the press themselves.
Below of an example of temperatures for some materials that we have tested in our test-laboratory.
NYLON PA 12: 90°C
ARCHITECTURAL LINE: 70°C
CARBONIUM (PA-CF): 60°C
IGLIDUR I 180: 85°C
UV ASA: 75°C
**POLYPROPYLENE: 105° to 45°C
*PLA: attention if you want to print PLA and have easy detachment of the piece suggest nozzle having a height slightly higher than the technical materials.
** POLYPROPYLENE: with this material it is mandatory to have the LENE PLATE. With this buildplate you can print either with brim with that raft. Z-axis calibration and installation of the buildplate is equals to normal Flatforce. For the first layer is recommended to have a temperature of 105 ° C, fans off or to 10%. The second layer buildplate temperature must be 80 ° C, bringing the fans to 40%. To third layer bring the buildplate at 60 ° C while the fan to 60%. From the fourth layer to then bring the buildplate temperature to 45-50 ° C and constant fan to the maximum, then 100% (like PLA prints). It is advisable to LENE PLATE solely and exclusively Polypropylene printing, other materials are not supported and can make the buildplate inoperable.
Useful tips for printing
The temperature data are approximate and can vary from 15-20%, greatly it depends on the material. If you make small prints (up to 60 mm per side) of the printing temperatures may be lowered up to a 20%.
Not all materials can be compatible with flatforce, as written before, much depends on the manufacturer and the mixing ratios used with other polymers or additives, so do not be assured that Flatforce works 100% with all the materials on the market.
The removal of the piece is greatly facilitated if you are using the brim or raft at the base of the press. Simply using a spatula, it does it stick between the surface and the first layer, proceeding with the detachment ring road around the perimeter of the prints. We strongly advise against doing levers too hard with the spatula or other metal instruments, when they could ruin superifice micro porous Flatforce.
To get the best print removal, we recommend you do this cold floor, or to a maximum temperature of 40-50. Remove one release to the operating temperature of the floor can ruin the plan.
We recommend not to remove the printing using only the use of hands with an action of vertical force or torsion, as the print may break and may remain glued to the floor only the base, also strives over due to the press plane.
Can occur in some prints the release of residues in Flatforce, this is mainly due to the porosity of the buildplate. To this as in the previous chapter we recommend removing printing with the spatula and use a base with brim or raft. With this system you will have a base of perfect printing and without release of waste. In the case in which there were to be of the residues (they vary much in material material) suggest proceeding or with a surgical knife or more and with a sharp spatula. The method is always tangential, never under any circumstances cut directly Flatforce surface.
Flatforce is able to resist to acetone (could remove residues of ABS, NOT nylon or other materials). But we do not recommend the use because it can leave a slurry of material evenly, fill the small micropores and making flatforce substantially smooth.
Always and in any case we recommend mechanical removal action and not chemical.
DO NOT USE: metallic brushes or similar. With this kind of tool, the microporosity can be removed completely
This chapter may help you to get the best prints perfomance with techincal material in some difficult prints.
The bottom of the prints will be rough?
Yes, the Flatforce surface is rough, so the bottom of your print will we rough. You you need a smooth surface, we suggest to make it witha post production or use a raft base.
Northype make custom Flatforce measure?
Yes, we can make custom measure of Flatforce and Lene-Plate.
If I want to print with PLA, Flatforce is necessary?
No, we have develop this kind of buildplate to print techincal material such as ABS, Nylon and other high-warping materials. Flatforce is compatible with PLA. But if you print only PLA, glass bed with hair spray could be the best solution.
How much is tolerance of flatness?
