If the problem persists, you can ask our customer service team via the contact form that you can find in the Contact section.

Availability of a product

All orders are subject to availability.

The majority of filaments are sent straight from the manufacturer warehouse to the customer, what is known as drop shipping. The delivery period is usually set by the transportation agency, as the order goes direct from our management system to the manufacturer logistics system.

If the manufacturer hasn't any of the items in stock at the time of the purchase order, we will contact the customer to offer alternatives (colours, types) or arrange delivery when they restock the product.

There can be several partial deliveries, when you order different products or products from different manufacturers.

In the case of products that we manufacture, such as our 3D printers, the delivery time will depend on our stock for immediate shipment and material availability to assemble the machines. In that case the average delivery time will be within one or two weeks. The delivery time will be specified by email and arranged with the customer.

In case we don't have materials in stock to assemble, due to circumstances beyond our control or unforeseen causes, the term can be several weeks. In this case, we will contact the customer to indicate the estimated delivery timeframe, or to cancel the order and refund the payment.

If you have any questions, you can contact us at the e-mail address: Account soporte@3dlimitess.com.

Order notifications by e-mail

We will send you automatic notifications to the email address you have provided, with information about tracking, invoice, etc.

If you don't receive these notifications, it's possible that your email provider is marking these messages as junk (spam). Check if the mail is coming to your Spam box and add us to your safe senders list.

Is VAT included?

All prices include VAT, unless indicated otherwise. In any case, invoices will be provided with a breakdown of VAT or other taxes.

In the event that the sale is carried out to foreign companies and professionals within the European Union, with TAX ID/VAT number, validated by VIES, the tax shall not be included; so they can convert the imposition to their country type of tax by themselves; if this is not VIES validated, VAT will be reflected with the corresponding Spanish VAT tax (21%).

What is the status of my order?

You can check the status of your order in the personal area My account.

In case of doubt you can contact us through the form that you will find in the Contact section.

What warranty do the products have?

All items offered in our web page have the legal European warranty (Spanish Consolidated Text of the General Law for the Protection of Consumers and Users RDL 1/2007), for a period of 2 years from the date of purchase for individuals. In the case of a juridical person (companies, associations, professionals, communities, etc.) the warranty will have one-year duration. In any case, they are subject to the laws and regulations at the time of sale.

The warranty doesn't include defects caused by neglects, beatings, use or misuse, connection to the electricity network other than the one stated in the users manuals, incorrect or negligent installation, or materials subject to wear their normal use. The filaments will only have the manufacturer's warranty in the event of obvious defects of manufacture, including other consumables.

As any technology item, the warranty doesn't cover damages caused by viruses, restoring programs, loss of data or information deletion. In the case of incidents under warranty, you can choose the repair, replacement, discount or refund, in the legally established terms.

Can you lose the warranty?

You can lose your warranty if the product is modified, altered, or in case of unauthorized replacement on any of their elements.

You can lose your warranty if the identifying number is manipulated, or the product is repaired by your own, without the knowledge or consent of the Technical Department.

You can lose your warranty if the equipment has been damaged, beaten or rendered useless.

All our shipments with SEUR have tracking number and signature collection. Our own logistic operators have online methods for monitoring and traceability throughout the process to ensure the quality of transport and delivery to the recipient.

In the case of not being at home at the time of the delivery, the transportation agency will leave a notice to arrange a new delivery. If delivery attempts are not possible at the time established by the logistics, the order will be returned to 3D LimitLess, being the customer responsible for the storage and logistics costs.

Damages in the receipt of shipments

We always pack our orders as best as possible, protecting them in boxes with foam, paper or air fillers. However, any incident may occur, beyond our control.

In the event of packaging external damage, this should be indicated at the time of the delivery (in the delivery note, to the driver), and if possible, taking pictures of the exterior damage or situation.

Any incident related to the transport shall be communicated urgently to 3D LimitLess, within a maximum time of 24 hours from the time of the delivery. This will expedite the process to resolve the incident with the transport company insurance, and refit the order as soon as possible.

Can I return a purchase?

Of course, you have up to 14 calendar days to withdraw from your purchase or part of it, counting from the f delivery date of the order, according to legislation. However, there may be exceptions, such as custom-made items, projects performed on an order basis, and supplies that have been unsealed.

What is the return policy?

It's essential that the products are returned in their original packaging and with their original components (manuals, accessories or promotional gifts, if any) along with the invoice. In case that the return is carried out in other conditions, we will deduct the replacement costs of the product, so that it can be suitable for the resale (packaging, plastics, protections), reserving the right to refuse the return, if there is any damage or sign of use.

To request a refund of an order or product, you must always contact to customer support at soporte@3dlimitless.com. We do not accept returns which have not been previously authorized.

Unpacking

You can consult the printer manual here. We detail the process of unboxing here.

Initial setup and commissioning

We detail the process of setup and commissioning in the manual, which you can download from here.

Load of filament

The first thing you should do is load the filament. Ensure that the print head temperature is suitable for the specific material. See in the filament manufacturer's technical sheet the range of appropriate temperatures for each one. Generally, a temperature of 200ºC is appropriate for PLA, while for ABS will be about 250ºC.

In the 3D printer manual, we tell you in detail how to perform the load operation, and the print material purge.

Filament unload and filament type exchange

When we switch from a filament with lower temperature (as the PLA) to one with higher temperature (as the ABS or copolymers), we must remove them at their working temperature, retracting the filament from the application or control panel, until we can see that there is no filament in the head or through the Bowden tube. We can then press the cam on the extruder (in golden colour) to remove the filament from the tube completely.

If we change PLA (200ºC) to ABS (250ºC) before feeding the ABS filament, the temperature must be raised above the temperature of the material we have removed (about 235ºC for example), to ease the ABS to push the PLA material remains on the nozzle. Once the ABS emerges from the nozzle tip along with these remains, we will put the head at normal operating temperature for the ABS filament, and we will do an extrusion test.

To do it the other way, from ABS to PLA, we must keep the temperature slightly below the optimum for the filament (240ºC, for example), and load the PLA that will easily drag the ABS. Immediately thereafter, put the temperature of PLA, to avoid charred remains in the print head. Then, you should do a filament extrusion test.

In case that you change materials frequently, it is advisable to make a print head cleaning with nylon filament to keep the nozzle free of impurities. We tell you how to do it in this blog entry…

Self Leveling

3D LimitLess 3D printers are equipped with a dynamic compensation system for the printing surface, or auto levelling. It uses a device that takes precise measurements (0.01mm deviation accuracy) with a probe at the start of the 3D print. With these measures, it establishes the topography of the surface that will be compensated with the Z-axis as the layers are being printed, achieving a greater precision and more perfect geometries.

This routine is added by the printing software at the beginning of the print, by adding a command G29 to the GCODE sent to the machine. It is necessary that this code is present in the software. All information on how to do so in the Slic3r or CuraEngine is in the user manual, which you can see here.

It is possible to make offset adjustments even thinner, slightly modifying the separation of the print head respect to the bed from the control panel, although it is not necessary under normal conditions, as our printers are factory calibrated and tested with the optimal values.

Jams

In the case that a filament jam occurs in the print head, try to remove the Bowden tube that leads the filament to get the filament out. It is necessary that the print head is at the right temperature to proceed to remove the tube.

Once it's at the right temperature, press the pneu-fit extruder connector and, at the same time, gently pull from the Teflon tube, allowing it to slide a few centimetres by pressing the extruder cam. Once this has been done, repeat the operation with the pneu-fit connector on the print head side, taking care not to get burned. The filament with Teflon tube should come out. Cut the thickened or deformed part of the filament and remove it from the tube. Fit the Teflon tube simply by pressing it until the stop, and feed again the filament through the tube, checking that plastic emerges correctly from the nozzle tip.

Print head Maintenance

The print head is one of the most important parts of the 3D printer. It is, to a great extent, responsible for printing right all layers and materials. It must be kept clean from plastic or waste, with a wire brush or tweezers on a regular basis. This must be done with the print head set at the proper temperature to ensure that the waste is fused and can be easily removed. Avoid clean filament waste when cold or rigid, because it could damage the print head. Do not use any cleaning liquid or solvent. Do not turn or unscrew the heater block!

General maintenance, care and cleaning

The printer does not need more maintenance than time to time cleaning with a brush along their V-grooves where the X , Y and Z wheels roll. This 3D printer is lubrication-free and there is no need to replenish oil or any other liquid. It is advisable to remove any twine or rest of extruded plastic once a print job is done.

We advise you to clean very well the printing glass with soap and dishwasher once it is cold; rinse well and dry completely before you replace it in the machine. Make sure it is completely free of grease, fingerprints. Iif necessary, you can clean it with isopropyl alcohol. The tempered glass is strong but, if not treated delicately, it can break. Caution: in the event of glass breaking, contact technical support to purchase a replacement.

The toothed belts usually last several years under normal use. If any of the two toothed belts get loose or show signs of wear or breakage, please contact technical support.

Be careful not to move or force the engines when they are in operation, as well as to avoid holding or lifting the printer from any movable axis.

Once the work is finished, remove the filament spool and store them in a cool and dry place, because humidity will degrade it in no time, so you will keep the printing characteristics of the filament until the next printing.

Reading the user manual is an important part of the use and maintenance of the 3D printers, and you should do this before, during, and after the use of the machines. You can download it from here.

Repetier

Repetier Host (https://www.repetier.com/) is the software that is responsible for managing all processes prior to the generation of a code (Gcode), so the machine can understand it, to be able to print 3D data. This software is responsible for managing communications by USB, coping or reading the SD card, positioning the 3D part to print on the surface, communicating with the slicing software (Slic3r or Cura) and manually managing of the 3D printer (moving, extruding, retracting, stopping, etc.). The printer must have some configurations in the Repetier Host configuration menu to work correctly. Follow the steps in this manual to learn how to configure easily these parameters, here.

Slic3r

Slic3r is one of the most advanced slicers program that exist. Developed by Alessandro Ranellucci in Italy; it is OpenSource and the page of the project is http://slic3r.org/.

Its usage is simple and it has powerful options for more advanced users, since we have control over hundreds of parameters to be able to print in 3D with quality, even the more complex parts.

We show you in the user manual how to configure the software to work seamlessly with 3D LimitLess 3D printers, which can be downloaded from here.

Cura

It is probably the easiest slicer software, and at same time very powerful. It is an Ultimaker development for the OpenSource community and it's open to any 3D printer brand. CuraEngine is integrated in Repetier Host. CuraEngine is the slicer engine behind the standalone application Cura to further simplify the process of slicing.

We show you in the user manual how to configure the software to work seamlessly with 3D LimitLess 3D printers, which can be downloaded from here.

File formats

Repetier Host supported file formats are .STL, .OBJ, .MFA, .3DS, in addition to the .GCODE and its possible variants .G, .NC and .GCO. The gcodes directly loaded in Repetier Host must be edited to include the start and end Gcode routines in the imported code, otherwise it may not be possible to print correctly or do not interpret all commands.

The 3D format files created or downloaded with other programs, must be previously exported to any of the compatible formats with Repetier to be sliced.

Printing supports

Both Cura and Slic3r have options called supports, which are meant to be able to print parts with cantilevers or angles that could not be printed in the air otherwise. These supports are necessary on the basis of the geometries to be printed. They can be configured in the menus of Cura and Slic3r, so that they can be easily removed once printing is over. We explain how to do this in the manual, which you can download here.

Printing manuals (ESP/ENG)

The manual for our printers is available to be downloaded in PDF format. We recommend that you read it thoroughly before any use, to learn about security measures and precautions, as well as specific aspects of usage necessary to know. You can download them here.

Printing Tips

Ensure that the external wall or perimeters of the parts are robust enough. We recommend at least 1 mm thick perimeter, keeping in mind that a width of 0.4mm is extruded with a standard nozzle. Therefore, at least 2 processes must be configured for the perimeters.

Regarding moulded parts, the whole pieces are made of the same material. However, the infill is rarely solid in 3D printed parts, so weight can be reduced and material can be saved by making the piece layer by layer. The density of the infill depends on the desired resistance to withstand the layers built on these refills. You can change the slicer programs parameters to get the optimal infill percentage for each job and display it previously.

Thermoplastic materials used for 3D printing have different physical properties or mechanical behaviours. It's necessary to respect the manufacturer's temperature settings and follow his recommendations to print (speed, density, forced cooling…).

The parts can be scaled, rotated, deformed, stretched and reflected in the printing software. Furthermore, multiple parts can be copied in the same printing, as long as there's enough space available on the printing surface.

The printed filament may shrink when it cools, just like any thermoplastic. This is an aspect that we must take into account when printing some object with precision. The resolution of a printed piece is measured in the Z-axis. In addition to this, there is a minimum resolution in X and Y that is given by the diameter of the printer nozzle. The smaller it is, the slower it will be.

Additional nozzles are available with larger or smaller tips. Moreover, there are nozzles prepared for intensive usage of abrasive materials, such as filaments with compounds of metals, wood or carbon. In case of occasional usage of these filaments, the standard nozzles are also adequate.

Printing errors guide

In our printer's user manual, we have a graphic description of the various malfunctions which may occur in the process of 3D printing. You can download it from here.

Guide of filaments

There are a lot of filament types from many manufacturers, and this area is the one that has demonstrated more progress, achieving better materials for 3D printing.

Each filament is tested by their manufacturers for best performance such as the print speed, fusing temperature and temperature resistance. Other requirements have been taken into account, such as printing on a hot or a cold surface, the need of any type of adhesive, and the possibility of deformation or shrinkage…

All of these factors are indicated in the filament technical sheet and they have been parameterised in the print profiles that we upload to our website, as we are testing each filament in our machines. You can also find tips and tutorials in addition to other information on the filament manufacturer's website.

Our main filament manufacturers are Fillamentum, FormFutura, ColorFabb and Taulman that offer an extensive range of materials and features, to find the right one for each 3D print job.

Our printers can operate virtually with any filament manufacturer on the market within the standard 1.75mm filament diameter. Because of the characteristics of the 3DLimitLess ILC extruder, it is not recommended to use flexible filaments without the V2 Plus extruder add-on. That is optionally available in our web shop.
