Equipment / 3D Printer (SLA)

Introduction

SLA 3D printing is a way of creating small, custom objects from UV cured plastic resin. The Form One+ 3D SLA printer is a new item of equipment that is not yet commissioned. Watch this space!

Owners

The Owners are those nominally in charge of the equipment, organising its maintenance, training others to use it, and generally being a point of contact.

The current Owners of the Form One 3D printer are:


If you have any questions, problems or concerns around the Form One, these are the people to contact.

General Health and Safety

The Form One is an expensive tool with a (small) risk of injury, so is very important you know how to use it to avoid damaging yourself and the machine. The Form One is a potentially dangerous piece of equipment which must only be operated by members who have received appropriate training and who take due care. The top things to always remember when using the Form One are:

  • ONLY USE THE FORM ONE IF YOU HAVE BEEN TRAINED
  • ONLY USE THE FORM ONE IF YOU HAVE READ THE INSTRUCTIONS

As a responsible user, you should be very aware of the following risks and how to deal with them:

POISONING - The resins and solvents used with the Form One may be poisonous if ingested.

  • Read the substance safety sheets, which can be located nearby to the printer, before use.
  • Always use Personal Protective Equipment, especially gloves, and take care when handling chemicals.
  • Do not consume food or drink in the vicinity of exposed chemicals.
  • In the event of skin contact with resin or IPA, rinse immediately with plenty of water.
  • In the event of ingestion do not induce vomiting. Rinse mouth thoroughly. Seek medical advice.

SKIN IRRITATION - The resins and solvents used with the Form One may be irritants to the skin.

  • Always use Personal Protective Equipment, especially gloves, and take care when handling chemicals.
  • Promptly wash contaminated skin with soap or mild detergent and water.
  • Promptly remove clothing if soaked through and wash as above.
  • Get medical attention if irritation persists after washing.

EYE IRRITATION - The resins and solvents used with the Form One may be irritants to the eye.

  • Always use Personal Protective Equipment, especially eye protection where there is a risk of splashing.
  • Make sure to remove any contact lenses from the eyes before rinsing.
  • Promptly wash eyes with plenty of water while lifting the eye lids.
  • Continue to rinse for at least 15 minutes.
  • Get medical attention if any discomfort continues.

FUMES - IPA solvent evaporates from open containers.

  • Run the ventilation/extraction system when working with IPA solvent.
  • Always replace the lid(s) on IPA containers immediately after use.
  • In the event of a significant (> 250ml) spill of IPA, evacuate the space and open the external doors to ventilate.
  • In the event of discomfort (light headedness, feeling sick etc) move the exposed person to fresh air at once.
  • Get medical attention if any discomfort continues.

FIRE - IPA solvent is highly flammable, Form One resin is flammable.

  • Avoid using IPA when an ignition source exists, such as a laser cutter in use.
  • Ventilate fumes to reduce the risk of combustion.
  • Always replace the lid(s) on IPA and resin containers immediately after use.
  • Always store IPA in the flammables cabinet when not in use.

SHARP TOOLS - Tools used to remove parts from the build plate are sharp with a risk of cutting.

  • Never push a sharp tool toward yourself.
  • Take care when handling sharp tools and replace in the correct storage location after use.
  • Clean resin contamination from tools to prevent slipping.

ELECTROCUTION - As with all mains powered devices there is a small risk of danger from exposed wires.

  • Always do a manual check that the wiring is safe, no cores are exposed or wires trapped.

Resins used in the printer

Makespace currently stocks the following resins. If you want to use your own resin you must also use your own resin tank and avoid any contamination of stock resins.

Clear Resin - FLGPCL02

Clear resin polishes to near optical transparency, making it ideal for working with light or showcasing internal details.

Supports print resolutions 200 (fast print mode), 100, 50 and 25 microns.

Grey Resin - FLGPGR02

Grey resin is good for general purpose prototyping and design, excellent for capturing small details.

Supports print resolutions 100, 50 and 25 microns.

Black Resin - FLGPBK01

Black resin is formulated for models with very small features and intricate details.

Supports print resolutions 100, 50 and 25 microns.

Tough Resin - FLTOTL01

Tough resin is durable and resistant, ideal for snap-fit joints and rugged prototypes. Requires UV post-cure.

Supports print resolutions 100 and 50 microns.

Specific Safety Tips

The major risk to safety is from spillage of resin or IPA. Work thoughtfully and calmly, never rush when handling chemicals however experienced and proficient you might be. When combing resin tanks for waste material take great care not to form a wave of resin which may overflow the tank. When agitating an IPA container, ensure the lid is properly fastened and also hold it in place as a backup.

IPA fumes are dangerous to inhale and are flammable. Minimise exposure of IPA to the environment. Clean up small spills with paper wipes and remove them from the building, do not leave them inside where the solvent will avaporate. In the event of a large spill evacuate the space and ventilate it well by opening external doors and running the extraction system. Remove any sources of ignition. Do not return until the fumes have cleared.

When removing a part from the build plate, take care with sharp implements. Never force a chisel in the direction of your hand or any other body part. Ensure the build plate is clamped securely.

Use the Personal Protective Equipment provided:

  • Disposable nitrile gloves
  • Disposable apron
  • Eye protection

Avoiding Damage to the Machine

The Form One printer is a precision instrument. Handle it with respect at all times and avoid impact and tipping.

ALWAYS REMOVE THE BUILD PLATE BEFORE REMOVING THE RESIN TANK

Resin will drip from the build plate and from the printed part after printing. If the resin tank is not present the drips will contaminate the laser mirror, requiring an expensive repair and potentially taking the printer out of service for an extended period. Any member observed to break this rule will have their Form One authorisation revoked permanently.

Always replace the resin tank blank after removing the resin tank. Minimise the time that the mirror is exposed to dust and other potential contamination.

Loading and Unloading Resin

Always wear disposable gloves when handling resin or IPA solvent

Disposable aprons are also available to protect your clothing. Use eye protection if there is a risk of splashing.

LOADING RESIN

Each resin formula is assigned its own tank, stored in the purpose built cabinet next to the printer. The type of resin can be identified by a name engraved into the shelf, and a name and part code label on the back of the tank. To avoid confusion always return the resin tank to the correct shelf.

Different types of Form One resin must never be mixed or cross-contaminated, not even a little bit

Before removing a tank from its shelf, check the fill level against the black "Maximum level" line printed on the front. When filled to the line the tank contains 200ml of resin. If there isn't enough resin in the tank to complete your build, top it up. To top up a tank, remove it from the storage shelf and place on a clean flat surface. If you get dust or scratches on the bottom of the tank these can cause failed prints, so take care. Retrieve the corresponding resin bottle from the Resin Cupboard below the printer, taking care to double check that the tank and bottle labels match, then slowly top up the tank level. Add a little resin at a time, allowing the level to settle before continuing.

Never fill a tank above the maximum fill level - it will overflow and damage the printer

If you do over-fill a tank, carefully pour the excess into the corresponding service tank which can be found in the same cupboard as the resin bottles. Again, take great care to select the correct tank, checking the label carefully. If any resin spills onto the outside of a tank it must be cleaned thoroughly with a clean cloth and IPA solvent.

When the tank contains sufficient resin for your print, remove the protection plate from the printer and store in the cupboard. Slide the resin tank into position in the printer until you hear and feel a click. Take care not to contaminate the mirror of the printer with dust, resin or any other material. Close the printer lid quickly after loading resin to minimise dust contamination. Remove the tank lid if you haven't already done so, and store next to the printer.

UNLOADING RESIN

Always remove the build plate before removing the resin tank

Remove the tank from the printer and place on a clean flat surface. Immediately replace the protection plate and shut the printer lid.

During printing lumps of uncured resin can build up in the tank and can be impossible to detect by eye. To leave the resin tank in a serviceable state for the next user you must remove any such material using the resin comb located in the Tool Cupboard below the printer. Place the resin comb into the tank at one end, teeth downwards so the guides rest on the tank walls. Draw the comb very slowly through the tank, taking great care to avoid a bow wave of resin overflowing the tank ahead of the comb. Allow the resin level to settle every 20 - 30mm. When you reach the far side of the tank withdraw the comb, scooping any hardened material with it, and allow the excess resin to drip back into the tray. Taking care not to drip resin onto the surrounding area, remove the comb and wipe with a disposable cloth before placing it into Cleaning Tank 1 for a few minutes. Don't leave the comb in the tank for longer than this as it will eventually dissolve. Once clean and dry replace the comb in the Tool Cupboard.

Finally fit the tank lid securely and replace the tank onto the correct shelf of the storage cupboard.
