Tramming 3d printer
bed leveling - How do you level (or tram) your build surface correctly?
Definition of leveling
Tramming, often referred to as "leveling" in the 3D printer world ("tramming" and "leveling" is used interchangeably, but "tramming" is the correct nomenclature), is the process of creating a 2D plane of the build surface that is parallel to the nozzle at the whole print area (usually the X-Y plane).
Why tramming?
In order to adhere the hot filament from the nozzle it is essential that the distance between the nozzle and the build surface is as constant as possible. Increase of the gap may cause the filament to not be squished enough and it may be dragged instead of deposited or create an insufficient bond to cause problems later in the print job when e.g. shrinkage of the object comes in play.
How to tram the surface?
To tram the build surface (a build surface comes in many shapes and forms, sheet of glass, bare aluminum plate, some sort of coated heated surface, etc. ) most printers are equipped with at least three so-called "leveling screws". Why at least three? It takes a minimum of three screws to fixate a plane in space, more screws cause the bed to be over-defined or indeterminate, but with a flexible build surface it is quite common to have 4 screws although it is causing a statically indeterminate system. So, these screws need to be adjusted as such that the build surface if parallel to the nozzle.
First step is to home (What is homing? What is the purpose of homing?) the printer, homing from the tag wiki reads:
The process of determining the location of a 3D printer nozzle in three dimensions using a reference point (home location) is referred to as "homing". Homing should occur before every print and involves bringing the X, Y and Z-Axis motors to pre-defined limit locations (usually these are endstops). Pre-recorded homing data offset values determine the position of the build plate origin with respect to the endstop locations.
Once homed (with G-code G28 or through the graphical user interface of the printer display) , the origin (0, 0, 0) of the printer is known, from this origin you can determine the level. Note that the X and Y is usually correct (if not, see How to center my prints on the build platform? (Re-calibrate homing offset)) the Z offset depends on the height of the Z endstop and the leveling screws. For a surface that uses a sensor as endstop (see e.g. Automatic Bed Leveling (ABL) with a sensor (BLTouch, inductive, capacitive), how does it work?) the offset is defined by G-code (M851) or through the user interface of the printer display. Note that automatic bed leveling (ABL) is not magic, you still need to provide a trammed bed that is as level as possible, the sensor merely scans the surface and adjusts for larger imperfections of the build surface. After homing, move the nozzle at a certain Z value to the corner of the origin, which is usually the front left) (0, 0, Z) or close to this corner (10, 10, Z), put a piece of paper (A4/Letter) on the build surface and lower the Z to 0 (or if you hit the build surface before you reach zero height, then lower the build surface) raise the build surface until you can feel the the paper drag slightly when pulled between the nozzle and build surface (alternatively you can use a feeler gauge, A4 paper is 0.
08 to 0.11 mm thick, so a 0.1 mm gauge will do fine). To be sure that the carriage hasn't been moved by the tramming, issue a homing command and move to the corner to the right and repeat the process to crete a slight drag of the paper when pulled between the nozzle and build surface. Note that tramming this point may have influenced the first point. Now repeat the homing and moving (for corners back right and back left) to start over again at the front left corner and repeating the whole process at least one to two times. This iterative process will deliver a trammed bed, the bed should now be parallel to the nozzle.
Trammed, but filament not adhering...
Once trammed the build surface should be parallel to the nozzle, if the distance (usually paper thickness) is too far or too close, adhesion or first layer deposition may fail or cause surface defects like ripples. If not adhering the initial gap between the nozzle and the build surface (paper thickness) might be too big, making this smaller may help squish the filament more so that it adheres better to the build surface.
Alternatively use an adhesive in between the build surface and the first layer, nowadays there are multiple dedicated sprays and liquids available, but some house hold product like wood glue, glue sticks and hair sprays could be used.
Build surface cannot or is difficult to tram
When the build surface isn't perfectly flat, tramming is a challenge, or doesn't provide a 2D plane at a fixed distance of the nozzle. In such cases, scanning the build surface and adjusting during printing might help to get the filament to adhere properly; this process is called automatic bed leveling or ABL (see Automatic Bed Leveling (ABL) with a sensor (BLTouch, inductive, capacitive), how does it work?). An alternative is UBL (see What is ABL or UBL? Is this the same?).
Tramming frequently?
The frequency of tramming depends on the quality and (mis)use of the printer to maintain the 2D plane parallel to the nozzle. For good quality printers the tramming is performed very seldom.

3D printers have come a long way over the past several years, but the process of bed leveling remains a pain point.
Let’s take a look at the different ways the problem has been tackled, and whether recent developments have succeeded in automating away the hassle.
Bed leveling and first layer calibration tends to trip up novices because getting it right requires experience and judgment calls, and getting it wrong means failed prints. These are things 3D printer operators learn to handle with time and experience, but they are still largely manual processes that are often discussed in ways that sound more like an art than anything else. Little wonder that there have been plenty of attempts to simplify the whole process.
Some consumer 3D printers are taking a new approach to bed leveling and first layer calibration, and one of those printers is the Anycubic Vyper, which offers a one-touch solution for novices and experienced users alike. We accepted Anycubic’s offer of a sample printer specifically to examine this new leveling approach, so let’s take a look at the latest in trying to automate away the sometimes stubborn task of 3D printer bed leveling.

In 3D printing, we often talk about leveling the print bed, although that’s not an accurate term. A bed that is level in our terms presents a flat surface that is parallel to the path of the print head, but within reason we care little about that. Instead we care more about it being parallel to the path of the head than it being perfectly flat. If we had a perfectly flat bed — say a sheet of glass — you’d think it might be pretty easy, but for some other materials it could be convex or concave or even have ripples all over the place. [Teaching Tech] shows you how to manually “level” the bed using a mesh but without using an automatic sensor.
You can see the technique in the video below.
When you use adjustments to level the bed, you are tramming it, but only the very pedantic use that term for fine adjustment. But no amount of adjusting bed springs will get rid of bulges and ripples. A common solution is to use a sensor to measure the distance to the bed and form a mesh correction. Then, as the printer head moves in the XY plane, the software will adjust the Z-axis to rise over bumps and go down if there is a concave portion of the bed. What [Teaching Tech] is doing, however, is a manual mapping. You won’t need to add a sensor to your printer to take advantage of the method.

Frequently Asked Questions
Which technology to choose: the method of fusing granules (FGF) or polymer filaments (FFF / FDM)?
What are the kinematics and mechanics of the Discovery equipment?
In this respect, all Discovery equipment differs from budget additive solutions.
The products are based on the kinematic diagram of a CNC machine. Gears, pulleys, lead screws, no belts. HIVIN rail guides are used. The entire structure is made with European quality from advanced products in the machine tool industry.
What consumables can be used with Discovery products?
Any material (other than PEEK and PEKK) sold in bars or pellets. First of all, thanks to the heating of the table to 175 ° C and vacuum fixation, as well as due to the installed nozzles made of hardened steel.
How is such a large print platform heated?
A matrix of separate equidistant heaters is built into the platform from the bottom side; these modules provide uniform heating of the surface of the printing platform. The maximum recorded temperature difference over the entire area is 3°C.
How to speed up printing on such large dimensions?
There is a special method for properly emptying the internal volume, which you can learn more about from our technical experts.
This procedure will have very little effect on the strength and elasticity of the print object, but will still reduce the time by up to 60%.
It is important to consider that with a large range of large-sized products, it is better to consider Super Discovery 3D Printer or Super Discovery 3D Printer Workstation with a capacity of up to 11 kg / h (depending on the material used).
Is it possible to upgrade this equipment for a specific enterprise?
Yes. Most of the Discovery machines can be upgraded for a specific production project. This is possible, since the equipment was designed for the tasks of Production 4.0, and our specialists will help to integrate it correctly.
What is the warranty for this equipment?
24 months, which is 1.5 - 2 times more than analogues from Europe, Russia and China. Permanent customer support is provided directly by the vendor or iQB Technologies specialists.
How to get a high quality product so that it can be handed over as a final product?
3D printing is basically a high quality preform process.
If you need to get the final product, it is suggested to use milling or turning equipment, manual machining, priming, painting or varnishing.
This is often not necessary as the product is not visible.
