Like FDM 3D printing, making certain a printed half sticks to an SLA machine’s construct plate is crucial to profitable resin 3D printing. Robust mattress adhesion is particularly essential when printing with resin as a consequence of a big majority of SLA machines favoring the stereolithography methodology of producing a print that’s hanging the wrong way up. Add on the truth that SLA printing entails some suction between the print and an extra floor–an FEP movie–and now there’s one other issue that may have an effect on the print’s attachment to the construct plate.

With gravity pulling in your hanging print and the additional pulling drive occurring from an FEP movie (if it isn’t hooked up excellent), it is no marvel that customers strongly recommend printing on a construct floor with a texture that the resin can maintain onto. Most, if not all, resin 3D printers include a textured construct platform proper out of the field. Nevertheless, over time, the crevices in that texture naturally get stuffed up by resin after a few Liters. It is then really useful to sand the construct platform to breed a few of that texture.

Understandably, the intestine response to listening to it’s essential take sandpaper to your machine that prices a whole bunch of {dollars} is not nice. So what’s an alternate choice to protect the integrity of your construct platform whereas nonetheless ensuring these prints persist with it? Enter LayerLock SLA Resin 3D Printing Construct Floor–a unbelievable resolution to attaining sturdy mattress adhesion for Laser, DLP, and LCD/MSLA resins.

Step 1 – Affirm Placement on LCD Display screen

• Clear off any mud, resin, and particles which will nonetheless be in your LCD display screen.
• Earlier than trying to connect the LayerLock SLA sheet onto the construct platform, we advocate you place it in your printer’s LCD display screen.
  • This ensures you’ve the proper dimension in your SLA printer and that the sheet attaches to the proper spot in your construct platform.

Word: After attaching the sheet onto the construct plate in Step 4, you’ll discover that the sheet doesn’t cowl the complete construct platform. That is intentional as some resin 3D printers use thick tape to carry the LCD display screen and just a little bit of 1 fringe of the construct platform lays over it. This will regularly trigger uneven mattress leveling–a contributor to poor mattress adhesion. Some printers might have extra exaggerated points than others.

By sizing the LayerLock sheet to the LCD display screen fairly than the construct platform, not solely does this resolve the problem detailed above, it additionally ensures that you’re nonetheless maximizing the complete print space so no print quantity is misplaced.

Step 2 – Sand Construct Sheet Floor

• When you’re happy with placement and compatibility, seize your LayerLock SLA sheet and flippantly and evenly sand the floor that shall be printed on. It’s the aspect that doesn’t have the tan adhesive liner.
  • Use the 220g 3″ x 3″ piece of sandpaper offered along with your construct sheet.
  • Word that it is essential to sand the floor earlier than first-time use. In case you print with out sanding it beforehand, it can have an effect on the effectiveness of the adhesion between the sheet and printing materials.
• When you end sanding, use isopropyl alcohol on a paper towel or microfiber material to wipe away the mud accrued on the sheet till clear.

Step 3 – Pull Off the Adhesive Liner

• When you’re happy with placement and compatibility, seize your LayerLock SLA sheet and take away the adhesive liner on the again of it.
  • Keep away from having your fingers contact the now revealed adhesive.
• With the adhesive aspect dealing with up in direction of the construct platform and away from the LCD display screen, place the LayerLock construct sheet again on the LCD display screen.
  • Be certain that to line up the sting of the SLA sheet towards the sides of the tape/LCD display screen.
• As soon as aligned, proceed to step 3.

Step 4 – Prep Construct Plate

• Be certain that your construct platform/construct plate has texture on it. In case you do not see or cannot really feel any texture on it, you’ll need to scuff it up just a little with sandpaper. If the floor is totally easy, then adhesive won’t persist with it.
• As soon as you’ve got confirmed there’s texture in your construct platform/plate, seize a paper towel and pour some isopropyl alcohol (ideally with an IPA of 90%+) on it.
• Use that paper towel to wipe down the floor of the construct plate you may be attaching your sheet to.
  • LayerLock SLA Construct Surfaces may be hooked up to construct platforms and versatile spring metal plates.
• Clear the floor till there isn’t any mud, particles, or resin on it.

• Word: If you’re attaching a magnetic base in tandem with a LayerLock sheet, observe all the magnetic base’s pointers for putting in their system on a machine earlier than trying to calibrate your resin 3D printer with a brand new construct floor.
  • Some machines require a brand new Z cease spacer to be put in earlier than calibrating. Please set up these new spacers as they are going to permit sufficient play to securely regulate your printer’s construct platform.
  • The next printers want a brand new Z cease spacer if putting in a magnetic base system:
    • Photon
    • Photon S
    • Photon Mono X
    • Elegoo Mars 2 / Professional 2
    • Elegoo Saturn
      *Word that this checklist includes machines that LayerLock SLA has appropriate sizes for accessible magnetic base methods. In case you determine so as to add a magnetic base system and LayerLock SLA sheet to an incompatible printer or unlisted appropriate printer, you’ll need to find out if a brand new spacer shall be wanted to account for the extra Z top.
• Reattach the construct platform again onto the resin printer.
• Loosen all leveling screws till the construct platform can freely regulate up and down.
• Be certain that the LayerLock SLA sheet didn’t transfer from its place throughout this step. If it did, realign the sides of the LayerLock sheet in keeping with the sides of the tape/fringe of the LCD display screen.

Step 5 – Connect LayerLock SLA Construct Floor

• Once more, if you’re putting in the magnetic base system on the identical time you are putting in a LayerLock construct floor, please be sure you adopted the magnetic base’s directions for set up earlier than continuing additional.
• Along with your LayerLock SLA sheet completely positioned on the LCD Display screen throughout the tape, transfer your Z to the house place.
  • To maneuver your Z to the house place, observe your particular resin printer’s directions.
  • As your Z strikes to the house place, don’t regulate something till it finishes the homing course of.

• As soon as the printer finishes homing, apply mild strain on the construct platform down towards the LCD display screen. The quantity of strain try to be utilizing needs to be the equal strain you utilize to maintain the construct platform leveled towards the LCD display screen as you tighten the leveling screws.

Step 6 – Affirm the Edges Caught to the Plate

• Increase the Z top in your construct platform excessive sufficient to the place you may safely detach it from the printer with out it hitting the LCD display screen.
• Detach it from the printer.
• To verify your LayerLock SLA sheet maximizes its adhesion to the construct platform, affirm all the LayerLock SLA sheet’s edges are flat towards the construct platform/construct plate.
• Use your hand to firmly press the complete construct floor towards the construct platform to additional guarantee every thing is touching towards the construct platform.

Step 7 – Calibrate Z Peak / Construct Platform Leveling

• Connect the construct platform again onto your machine.
• Be certain that the leveling screws on the construct plate are nonetheless loosened.
• Observe your SLA machine’s regular really useful calibration directions.
  • Not all resin 3D printers have the identical adjustable Z top or observe the identical steps so we advocate following the producer’s particular required/really useful pointers.
• As soon as you’ve got adopted your printer producer’s directions on leveling and have tightened the leveling screws, proceed to Step 8.

Step 8 – Load Your Take a look at Mannequin

• Select any mannequin you wish to check the mattress adhesion for the primary layer of your check print. We advocate one thing that’s small and fast like this skinny sq. so you may fine-tune your settings and regulate your Z top correctly if wanted earlier than leaping to testing a bigger print.

Step 9 – Print and Alter If Vital

• Print the skinny sq. check print from Step 8. In case you’re printing a unique mannequin, make it possible for is both 0.05mm tall or cease your print after it completes its first layer.
  • Once more, earlier than printing, be certain that the LayerLock sheet has been sanded. If not, observe Step 2 earlier than printing.
• As soon as the print is accomplished, permit extra resin to drip again into the vat or rigorously wipe any extra resin from the construct platform again into the vat with a silicone spatula or plastic putty knife.
• With a nitrile glove nonetheless on, gently rub your finger throughout the print.
  • If it requires a scraper and light-moderate drive to take away it from the platform, you are good to go!
  • If the next points come up similar to…
    • The half simply slides off the platform with simply your finger
    • Lifted corners
    • Air pockets beneath the print
  • …then take into account these potential resolutions:
  • Affirm you adopted Step 5–sanding the construct sheet and cleansing off the mud ensuing from sanding
  • Guarantee sufficient resin was within the vat to print your check print
    • Not sufficient resin within the vat could cause usually trigger air pockets/bubbles
  • If none of those resolutions resolve the problem, resetting the Z=0 top and re-leveling the construct platform could also be wanted. Repeat steps 6 – 8 till the primary layer requires a scraper and light-moderate drive to take away it from the platform.

Word: Please be sure you usually are not additionally printing with new resin if that is your first time printing with the newly put in LayerLock SLA Resin 3D Printing Construct Floor. New resin means a brand new variable which may be affecting mattress adhesion. We advocate first confirming mattress adhesion may be achieved with a resin you might be conversant in printing. As soon as that’s confirmed, then print with the brand new resin utilizing ideas from this How To Succeed information on easy methods to usually fine-tune most photopolymer resins to your SLA printer.

That’s it for set up! Your new construct floor is hooked up, every thing is correctly calibrated and also you’re now prepared to begin efficiently printing.

Last Printing & Upkeep Suggestions

• Re-leveling your construct platform is really useful when fine-tuning printing with a brand new resin.
• The next components exterior of LayerLock SLA’s management are nonetheless crucial for mattress adhesion success:
  • Utilizing the proper resin profile settings
  • Ensuring the pigments/dye of the resin haven’t settled to the underside earlier than printing
    • Instance: It is best follow to repeatedly stir/shake inexpensive resins earlier than printing so all of the dyes/pigments are distributed evenly. If left settled on the backside, the sunshine won’t shine via that means no profitable curing will happen. It’s possible you’ll have to stir the vat of resin once more after a specific amount of hours, relying on the model you’ve got chosen.
  • Having correct drainage holes on prints
  • Making certain your FEP movie is not too loosely or tightly hooked up to the vat
  • Having a calibrated Z top / leveled construct platform
    • A leveled construct platform may be tough to realize if the resin 3D printer has thick tape across the LCD show. With the LCD display screen beneath the best level of the thick tape, this will trigger an excessive amount of of a spot between the LCD display screen and FEP sheet.
  • Printing in an setting that’s room temperature (ideally inside 68°F – 77°F)
    • Something decrease than 50°F or increased than 100°F extremely will increase the probabilities for mattress adhesion and curing points.
• Frivolously sanding your LayerLock SLA Construct Floor is really useful for first-time use and both after each 5L of resin printed or every time mattress adhesion is noticeably misplaced.
  • Bear in mind to put on a masks whereas sanding to keep away from inhaling any particles.
• As with different construct surfaces, watch out when utilizing sharp objects to take away prints from the construct floor to keep away from unintentional knicks, scratches, and grooves on the floor.
• Clear the floor with 90%+ IPA isopropyl alcohol after each sanding.
• Wipe the floor and construct platform clear of any resin if switching between materials/colours.
• Keep away from soaking the construct platform with LayerLock SLA hooked up in any solvent for lengthy intervals of time.
  • There is a risk that solvents might erode the adhesive on the again of the LayerLock SLA construct sheet, thus decreasing the adhesive’s lifespan.
  • Wiping the floor with a lightweight quantity of IPA won’t be an issue.
