Properly\nconguring these parameters helps achieve an optimal balance between printing precision and\neciency.\n\n\n\n\nLayer Height\nLayer height refers to the veical stacking height of each printed layer (unit: mm) and is a key\nparameter determining print resolution and eciency.\nFor example, with a 0.4 mm nozzle, a smaller layer height (e.g., 0.12 mm) achieves ner layers,\nresulting in smoother suaces and richer details, but signicantly increases print time. In\ncomparison, a larger layer height (e.g., 0.28 mm) decreases print time but may produce noticeable\nlayer lines aecting suace quality.\n\n\n\n\n 41", "Bambu Lab P2S 3D Printing User Manual Chapter 5 Adjust Slicing Parameters in Bambu Studio\n\n\n\n\nRecommended settings:\n• Layer height is usually 50% of the nozzle diameter. The recommended range is 30% – 70% of\n the nozzle diameter. For example, when using a 0.4 mm nozzle, the recommended layer height\n range is 0.12 mm to 0.28 mm.\n• When optimizing layer height, consider model complexity, required strength, and nozzle\n diameter to balance suace quality and printing eciency.\nInitial Layer Height (rst layer height)\nThe height of the model's rst layer. Increasing the initial layer height enhances adhesion between\nthe model and the build plate, reducing the risk of warping or detachment.\nFor more details on layer height settings, please visit the Bambu Lab Wiki (wiki.bambulab.com/\nhome) for relevant guidance.\n\nSeam\nA seam is a small gap formed where the sta and end points of wall paths meet on the\nmodel suace, usually appearing as a veical line. This phenomenon is an inherent structural\ncharacteristic that cannot be completely avoided in FDM 3D printing.\nOn models with edges or protrusions, seams can be naturally concealed. However, on smooth\ncued or continuous suaces like cylinders, seams are more noticeable and can aect the\nexternal appearance.\n\n\n\n\n 42", "Bambu Lab P2S 3D Printing User Manual Chapter 5 Adjust Slicing Parameters in Bambu Studio\n\n\n\n\nTo achieve better print results, you can set the seam position in Quality parameters. There are four\ntypes of seam positions to choose from:\n• Nearest: Prioritizes concave or convex non-overhang veices to hide seams, especially suitable\n for models with sharp corners. If no suitable veices are found, it selects positions close to the\n end of the previous path to reduce travel distance and oozing.\n• Aligned: Aligns seam across layers, making them more concentrated and easier to post-\n process.\n• Random: Distributes seams randomly on each layer to avoid visible lines, but may cause\n irregular suace patterns.\n• Back: Fixes seams on the back side of the model, suitable for display models.\n\n\n\n\nFor more details on seam settings, please visit the Bambu Lab Wiki (wiki.bambulab.com/home) for\nrelevant guidance.\n\n\n 43", "Bambu Lab P2S 3D Printing User Manual Chapter 5 Adjust Slicing Parameters in Bambu Studio\n\n\nOnly One Wall on Top Suaces\nWhen enabled, the top suace of the model is printed as a single wall, helping achieve clean\nand neat suaces.

Proper suppo conguration can signicantly improve print\nsuccess rates and simplify post-processing.\n\n 48", "Bambu Lab P2S 3D Printing User Manual Chapter 5 Adjust Slicing Parameters in Bambu Studio\n\n\n\n\nIntroduction to Common Parameters\n• Type\n Normal suppos are generated using a standard linear structure, providing a stable and\n evenly distributed layout, fast generation, and easy removal from the model suace. Suitable\n for mechanical pas with regular structures and geometric models dominated by at or linear\n suaces.\n Tree suppos employ a “trunk and branches” branching structure built layer by layer, making\n contact only at critical stress points. They are ideal for complex cued suaces and detailed\n characters or a models, greatly reducing suppo material usage and avoiding leaving obvious\n marks on ne suaces.\n\n\n\n\n Normal suppo Tree suppo\n\n Auto means Bambu Studio generates suppo automatically based on the set threshold angle.\n Manual means that suppos are generated only in the areas you specify, using the Suppos\n Painting tool. For detailed steps on suppo painting, please visit the Bambu Lab Wiki\n (wiki.bambulab.com/home) for relevant guidance.\n\n 49", "Bambu Lab P2S 3D Printing User Manual Chapter 5 Adjust Slicing Parameters in Bambu Studio\n\n\n• Threshold Angle\n Threshold angle denes the steepest suace angle (relative to the horizontal plane) that can\n be printed without suppos. When the suace angle is smaller than this threshold and the\n suppo type is set to Auto, suppos will be generated. Adjusting this value is a quick way to\n control the amount of suppo generated. Lower values produce fewer suppos, higher values\n produce more. The default value is 30°, suitable for most models.\n\n\n\n\n• On Build Plate Only\n Enabling this option ensures that all suppos originate only from the build plate and do not\n attach to the model itself. This helps reduce suppo marks on the model suace, improving\n appearance quality and simplifying post-processing. However, for structures far from the build\n plate or completely suspended, this setting may not oer adequate suppo. It should be used\n carefully based on the model geomet.\n• Filament for Suppos\n\n Suppos consist of two pas: suppo base and suppo inteace. The suppo inteace is\n the contact layer with the model, and the rest forms the suppo body. These two pas can\n use dierent types of laments. If unspecied, the current layer’s lament is used by default to\n minimize lament change time. Typically, dedicated suppo materials (such as Bambu Suppo\n W and Suppo G) are chosen for printing the suppo inteace to improve removability and\n suace quality.\n\nIntroduction to Advanced Parameters\n• Normal Suppo Style\n\n\n\n\n # Grid: Projects overhang areas veically onto the build plate and expand outward to create\n regular, grid-like suppo columns. The suppos are stable and strong, suitable for large\n horizontal overhangs.\n # Snug: Grows precisely along the model contour, saving material and providing exible\n suppo shapes. It is well suited for complex or detailed areas.\n\n 50", "Bambu Lab P2S 3D Printing User Manual Chapter 5 Adjust Slicing Parameters in Bambu Studio\n\n\n\n\n• Tree suppo style\n\n\n\n\n # Tree slim: Features thin branches and an optimized overall structure. Suitable for small,\n lightweight overhangs. Its aggressive merging strategy reduces material consumption and\n minimizes removal marks.\n\n\n\n\n 51", "Bambu Lab P2S 3D Printing User Manual Chapter 5 Adjust Slicing Parameters in Bambu Studio\n\n\n\n\n # Tree Strong: Characterized by a thicker trunk and branches, oering a more robust structure\n with strong load-bearing capacity. Recommended for large or heavy overhangs where\n stronger suppo is required.\n\n\n\n\n # Tree Hybrid: Combines the advantages of tree and normal suppos. The software\n automatically determines the most suitable structure and applies it in dierent areas. This\n style oers a exible automated strategy aimed at optimizing suppo structures for dierent\n model pas.\n\n\n\n\n 52", "Bambu Lab P2S 3D Printing User Manual Chapter 5 Adjust Slicing Parameters in Bambu Studio\n\n\n\n\n # Tree Organic: Generated using biomimetic algorithms, producing natural, smooth, and\n cued branches. It intelligently routes suppo to reach overhangs while minimizing material\n usage and easing removal. Suitable for most models that require tree suppos.\n\n\n\n\n• Raft\n\n A raft is a base layer located beneath the model and suppo structures. It is used to enhance\n adhesion during printing, especially with warp-prone laments such as ABS. Rafts eectively\n prevent suppo detachment and lift the entire model o the build plate, isolating it from\n potential suace unevenness.\n\n\n\n\n 53", "Bambu Lab P2S 3D Printing User Manual Chapter 5 Adjust Slicing Parameters in Bambu Studio\n\n\n\n\n• Top Z distance\n\n The veical distance between the top of the suppo inteace and the underside of the model’s\n overhang.\n\n\n\n\n When using dedicated suppo inteace laments such as Bambu Suppo for PLA, Bambu\n Suppo for PLA/PETG, or Bambu Suppo for PA/PET, this value can be set to 0, allowing direct\n contact between suppo and model. When the suppo inteace uses the same lament as the\n model, a value of around 0.2 mm is recommended to prevent suppos from becoming dicult\n to remove. The table below shows how the Top Z Distance aects suppo removal and suppo\n suace quality:\n\n Top Z distance Ease of Suppo Removal Suppo Suace Quality\n\n Increase Easier Lower\n\n Decrease Harder Higher\n\n• Suppo/Object XY Distance\n\n 54", "Bambu Lab P2S 3D Printing User Manual Chapter 5 Adjust Slicing Parameters in Bambu Studio\n\n\n This parameter controls the horizontal distance between suppos and the model, with a default\n value of 0.35 mm. The greater the distance, the easier it is to remove the suppo, and it also\n reduces the risk of scratching the model’s suace. If the suppo is dicult to remove, consider\n increasing this value appropriately.\n\n CAUTION\n # The top Z distance and the suppo/object XY distance should be adjusted together.\n Their combination directly impacts model suace quality and ease of suppo removal.\n Finding the optimal balance is key to achieving ecient and high-quality printing.\n # It is recommended to remove suppos within 2 hours after printing. Prolonged\n exposure may cause moisture absorption, making suppos softer and harder to remove\n —especially when printing moisture-sensitive laments such as PA-CF, PA6-CF, or when\n using water-absorbing suppo laments like PVA or Suppo for PA/PET. If suppos are\n hard to remove, ding the model or cooling it before removal may help.\nFor more advanced suppo settings, please visit the Bambu Lab Wiki (wiki.bambulab.com/home)\nfor relevant guidance.\n\n\n5.6 Speed Settings\nSelecting the appropriate print speed helps improve print quality and accuracy. Bambu Studio\nprovides optimized default speed presets that work well for most print jobs. You may also ne-\ntune the print speed according to custom needs.\n\n TIPS\n Process presets already include all required settings for specic printing scenarios and are\n recommended for beginners.

Then, check whether the print\nconditions are compatible with your current printer and AMS model. Pre-process the lament\n(ding and calibration) as needed before sta a print to ensure stable and high quality results.\n\n\n8.1 Common Filament Types\nDierent 3D printing laments have their own physical propeies and applications. Choosing the\nright lament based on your printing needs helps improve print quality and model peormance.\nBelow is a brief introduction to several common laments. For detailed features and specications,\nsee the Bambu Lab Filament Guide (https://bambulab.com/lament/guide).\n\nBasic Filaments\nPLA\n• The most common ent-level 3D printing lament. It\n is eco-friendly, non-toxic, biodegradable, and easy to\n print, but has limited mechanical peormance.\n• Suitable for eveday prototyping, home printing, and\n low-load applications.\n\n\nPETG\n• Oers good mechanical peormance, with water, heat,\n and chemical resistance. However, it must be kept d,\n and its smooth suace can show scratches easily.\n• Suitable for containers, durable pas, and functional\n pas.\n\n\n\nAesthetic Filaments\nPLA Silk/Silk+\n• Has a silky texture and high gloss. However, it must be\n kept d, as moisture can easily cause stringing.\n• Suitable for models that require a silky texture or\n metallic sheen.\n\n\n\n\n 71", "Bambu Lab P2S 3D Printing User Manual Chapter 8 Filament Introduction and Usage\n\n\nPLA Wood\n• Contains natural wood paicle additives for a matte,\n solid-wood-like texture. However, it must be kept d,\n as moisture can easily cause discoloration.\n• Suitable for natural or forest-style models. The matte\n texture also helps hide layer lines.\n\n\n\nEngineering Filaments\nABS\n• Oers good mechanical peormance and high\n durability, but is prone to warping.\n• Suitable for mechanical housings and functional pas.\n\n\n\n\nASA\n• Similar to ABS but with superior UV resistance.\n• Suitable for outdoor pas and automotive\n components.\n\n\n\n\nPC\n• Oers good heat resistance, strength, and rigidity, but\n is prone to warping and moisture absorption.\n• Suitable for high-strength structural pas, high-\n temperature applications, and mechanical components.\n\n\n\n\n NOTE\n Engineering laments may emit irritating fumes during printing. Use enclosed printers and\n ensure good ventilation.\n\n\n\n\n 72", "Bambu Lab P2S 3D Printing User Manual Chapter 8 Filament Introduction and Usage\n\n\nFlexible Filaments\nTPU\n• Highly elastic and wear-resistant, but relatively slow to\n print.\n• Suitable for exible models, such as shoe sole\n prototypes, seals, and cushioning pads.\n\n\n\n\n NOTE\n • The hardness of TPU lament is measured by the Shore A hardness. A lower value means\n the lament is softer, while a higher value means it is harder. Common hardness levels\n include 75A, 80A, 83A, 85A, 90A, and 95A.\n • It is recommended to print with TPU of 80A hardness and above. Higher hardness\n improves printing stability and reduces the risk of print failure.\n\n\nFiber-Reinforced Filaments\nCarbon Fiber Reinforced (-CF)\n• Carbon ber is added to laments such as PLA or PETG\n to signicantly improve rigidity and strength while\n keeping the material lightweight.\n• Suitable for load-bearing structural pas and\n lightweight structural designs.\n\n\nGlass Fiber Reinforced (-GF)\n• Glass ber is added to laments such as ABS to\n improve toughness and wear resistance.\n• Suitable for industrial mechanical pas and structural\n frame components.\n\n\n\n\n 73", "Bambu Lab P2S 3D Printing User Manual Chapter 8 Filament Introduction and Usage\n\n\nSuppo Filaments\nSuppo for PLA/PETG\n• A breakaway suppo lament with good print\n compatibility, easy removal, and smooth contact\n suaces.\n• Designed specically for use with PLA and PETG\n printing.\n\n\nPVA (Water-soluble)\n• A exible, biodegradable polymer with strong moisture\n absorption. It absorbs water from the air and dissolves\n in water. Commonly used as a water-soluble suppo\n lament in 3D printing.\n• Suitable for complex models or models where suppos\n are dicult to remove manually.\n\n\n NOTE\n Suppo laments are specially optimized for good stability.

Excessive extrusion resistance\n Check whether the spool rotates freely or if the lament is tangled. Clean or replace the PTFE\n tube, clean or replace the extruder gears, and unclog or replace the nozzle.\n2. Insucient extrusion\n Slightly increase the nozzle temperature or reduce the print speed. Unclog or replace the\n nozzle, and adjust the ow ratio in Bambu Studio accordingly.\n3. Under-extrusion at corners\n This may be due to an incorrect pressure advance value, requiring a recalibration of the ow\n rate.\n\n\n9.8 Stringing and Oozing\nStringing and oozing typically appear as thin lament strands or small blobs on the suace. It is\ncommonly caused by excessive extrusion, moist lament, or abnormal melting and ow behavior\nof the lament.\n\n\nPossible Causes and Solutions\n1. Damp lament\n D the lament.

Nozzle temperature too high\n Lower the nozzle temperature moderately to increase lament melt viscosity, making it less\n \"liquid\" and reducing oozing.\n5. Using low-density laments (e.g., PLA Aero) without reducing temperature or ow rate\n Lower the print temperature appropriately and adjust the ow rate to the range of 0.5 – 0.7.\n6. Worn or oversized nozzle\n Ensure the actual nozzle matches the slicing settings. Check the nozzle condition and replace it\n if worn.\n\n\n9.9 Gloss Dierence\nAt the same temperature, lower print speeds produce smoother suaces. At the same speed,\nhigher temperatures produce smoother suaces. If uneven gloss appears on the model suace\nduring printing, it is usually caused by dierences in lament melting or cooling rate, which aect\now and lead to changes in suace roughness. This issue is more noticeable on highly reective\nlaments.\n\n\n\n\nPossible Causes and Solutions\n1. Signicant dierences in print speed across dierent areas of the model, such as slowed\n overhang areas\n For large models, reduce the outer wall speed as needed. For small models, reduce the overall\n print speed. If necessa, disable Slow down for overhangs.\n\n 90", "Bambu Lab P2S 3D Printing User Manual Chapter 9 Print Quality Issues and Solutions\n\n\n2. High print speed when printing at a low layer height, such as 0.08 mm\n This may cause scale-like gloss dierences on the model suace. Consider increasing the layer\n height, lowering print speed, or raising print temperature accordingly.\n\n\n9.10 Interlayer Cracking\nInterlayer cracking occurs due to insucient bonding between layers, resulting in visible cracks on\nthe model suace. This issue is commonly seen when printing ABS, ASA, PC, PET-CF, PA-CF, and\nhigh-shrinkage laments.\n\n\n\n\nPossible Causes and Solutions\n1. Under-extrusion leading to gaps between lines\n Clean and unclog the nozzle, appropriately increase the nozzle temperature, or reduce the\n print speed.\n2. Weak interlayer adhesion or thin structural sections\n Increase the number of model wall loops or raise the sparse inll density to enhance strength.\n3. Excessive cooling\n Reduce fan speed appropriately, increase the bed temperature, and close the printer's front\n door and top glass cover.\n\n\n9.11 Seam\nIn FDM 3D printing, the sta and end points of each layer naturally form a seam.
